(Note: Mac Users may want to skip to the bottom)

After a number of years my old Windows Vista 32 bit installation was a little worse for ware. Having a laptop capible of 64 bit I decided to upgrade to Window 7 64 bit. After a fresh install of Windows 7, I began the process of installing drivers for the hardware I had. It wasn’t until I came to my trusty Belkin USB to Serial (RS232) converter, aka PDA adapter that I encountered a problem.

After visiting Belkin‘s website and looking up the driver page for the convertor, I discovered that Belkin didn’t support both Vista 64bit and Windows 7 64 bit. Here’s the details from their knowledge base page (can’t link it due to thier website design):

“Is the F5U409 USB PDA Adapter compatible with vista 64 bit?
No, this product is not compatible with vista 64 bit. It is compatible with Vista 32 bit computers. We do however have a similar adapter which is compatible with Vista 64 bit, you can use part F5U257 (USB-to-Serial Adapter).”

What a rip off? Not only doesn’t Belkin support their old hardware they try and get me to buy their new hardware!

Being a computer system administrator and programmer by trade, I knew there would be no physical reason the device would not work under a 64 bit operating system. It was down to Belkin not wanting to spend the time or money to update the driver. In most cases, it would simply be a recompilation of the existing driver.

Hence I began searching to see if anyone had got the device working. There was lots of webpages/forum posts about how people failed. Lots of posts indicating it’s not supported, even an official microsoft page indicating it’s not supported under Microsoft Windows 7. Then there were a few posts indicating to try various different drivers, most seem to relate to either the Prolific or FTDI chip/chipset which apparently exists on other models of the Belkin adaptors (F5U109?) and with other USB/RS232 converters and hence works with some other drivers. But sadly nothing about the Belkin F5U409 adaptor.

Hence I figured enough is enough. I had previously found a website where someone had pulled the adaptor apart to determine if the chipset was an FTDI chipset. Sadly it wasn’t it was instead a Philips P87C52X2BA microcontroller seemed to be used. Hence I did a lot of searching for that particular chip in google, all with no luck. Eventually I thought hmm, lets just see if we can find another USB232 converter that used a Philips chip.

Magic Control Technologies U232-P9 Adaptor

It was then that I found the MCT U232-P9 DB-9 Serial Adapter High Speed 230K USB SERIAL RS-232. This device used the “P87C52 – 80C51 8-bit microcontroller and PDIUSBD12 made by NXP Semiconductors founded by Philips.” It was perfect the chip matched. I hence spent quite a while working out who MCT were. It turns out that MCT stands for Magic Control Technologies. On the MCT website, on their driver page they had drivers for their USB/Serial convertor and they support Visa, Windows 7, 32bit & 64bit. So I downloaded the driver U232-P9 Driver.(Click Here for a Local Mirror incase MCT remove it)

I then crossed my fingers and installed it. After a quick reboot I plugged in my Belking F5U409 adaptor and it was detected! A quick check. It worked!

So to Belkin who wanted to force me to buy yet another product – support your products!

As a bit of an ironic twist, I later began cleaning up the original installed Belkin driver (I had tried the Vista 32bit version with no success). It was then that I discovered that Belkin don’t even write their own drivers but use Magic Control Technologies drivers! (You can find this by right clicking on the u2sxp.sys file that Belkin installs to C:\Program Files(x86)\Belkin\F5U409\Driver\u2sxp.sys and clicking the details tab). So not only are they not updating the drivers, they didn’t write them in the first place!

Finally, if your a Mac OSX 10 user you might also want to check the Magic Control Technologies driver page as drivers exist for you as well – shame on you Belkin.

I’ve been searching for a solution to this since buying my Windows 7 laptop a year ago and stumbled across your solution. It works for the two F5U109 adapters I have as well. Now I can use the GPS and motorcycle tuner I have that need a serial port. Thank you!
MBorge said,

You are an Uber Tech my friend! This does indeed fix my F5U109 thus extending the life of my old Wacom Intuos tablet. Thank you!
Drall said,

I recently got a new laptop and it has no serial port.

I had a staples USB to Serial, which worked with XP.

This driver works great thank you very much.

Now it is….
So I downloaded the driver U232-P9 Driver it Works! Now i can hook-up my Celestron Advanced GT telescope to My Starry night PRO PLUS 6.23 Software on my iMac intel-based Running Winows 7 on BootCamp
Mark said,

I’m in Australia and have a tag reader that I use to keep track of my cattle. Have been using F5U409 USB to Serial adapter. Stopped working when I bought my new Windows 7 laptop. Spent quite a few hours searching on the net for a solution before I found your article. Thanks to you and your willingness to share your solution it’s working again!
Mike said,

Thank you so much for figuring this out. I too had tried the Prolific drivers a few months ago, but of course they didn’t work.

Now I can connect to my router and firewall’s console port with my Windows 7 laptop instead of having to use an old laptop running XP.

You have been a *GREAT* help.
AC said,

Thanks! Worked great in Windows 7 64-bit.
Matt said,

That is the best help I have had on this. Thanks for your in-depth research. I have tried other driver options people have suggested…but this one is the only solution to the F5U409 adapter.

I volunteer my time and resources by providing a weather station that uploads it’s information to the multiple resources on the web. When I upgraded, I assumed there would be a driver readily available as the adapter is of fairly new builds if that is ok to assume. I thought, why surely there is a driver for this, compared to a Prolific adapter I have. Even the prolific had drivers for Windows 7 64-bit but the weather station doesn’t communicate with the computer with that adapter, even with the newer drivers. It was used for a radio interface adapter.

The only adapter I saw that would work with my station is this Belkin F5U409 adapter and this driver you have found works! Thank you so much. I already put a lot of my money into the station, the adapter, the software, etc. It’s things like this that Belkin wouldn’t understand and why I was searching for a whole reason not to get their latest adapter. But as I have found, they run a model like cell phones, just produce a newer model and let the old lay to rest.

Well, all is well now! This should be on Google’s ranks higher. The only way I found this was through another forum that linked to this. Thanks Benjamin!

Excellent. After having several pieces of hardware and software not compatible with win7 it’s good to get an older bit of kit working again.
Manny said,

I don’t even know where to begin thanking you for this. My desktop died and I was forced to get a newer machine with Windows 7. My Belkin adapter is crucial to a lot of radio programming that I do. I did a LOT of research and came up empty. I thought I was done. Thank you for sharing your discovery with us.

Benjamin, thank you for saving me additioanl frustration and wasting any more time/money on this issue. Your research and the MCT solution worked beautifully. Please accept my donation as Belkin does not deserve it
Sam Ali said,

Thank you very much. I was bummed when Belkin pulled the “not supported with win 7″ tactics. I am indebted to you for your time and expertise.
Sonnox said,

We have a device that will only work with serial ports and we have been advising customers to get adaptors like the belkin USBtoserial to get around the problem of not having COM ports on new PCs and also because Belkin advertised the adaptor have lifetime warranty this gives the customers some comfort in using them. The problem of having the drivers for windows 7 had us stumbled as we are unable to find any alternate solution.

Thanks spending the time finding the drivers.

Belkin, shame on you!!! so much for “lifetime warranty”
Matt said,

I just thought I’d come back and check on this page after my success. It seems many more are getting the same, positive results. Glad everyone else is getting the rather decent, not so antiquated adapter working also!

Cheers!

Hi Man

Thanks a lot!!!, I just got the driver you mentioned here and it worked wonderful.
david said,

Greta tip. In our office we have the Belkin as well as a Targus PA088U converter. Both devices suffer from the 64 bit driver issue.

Out of desparation I just installed the driver and to my relief it works like a charm with the Targus PA088U.

I have contacted Targus support over this & look at the crud they responded with. “There are no driver for a 64 bit operating system as there is no way to change the hardware inside the the PA088U, nor will there ever be”

I smell bullshi1t…

Ben all I can say is ‘thank you, thank you, thank you. My husband had a Belkin PDA Adapter and had also updated to 64 bit laptop. This adapter is used for outboard motor analysis and after installing the driver you added it now works. He was getting very frustrated and thought he had to buy a new cable.

Dex said,

Hey, thanks this worked exactly as you described for my Belkin FSU409 that I’m connecting to CISCO network devices to a console cable.

I went the useless Belkin support, and created two accounts, but could not login. I called the 800 number and was sent to India for support. They basically said it was not supported and I should return the product. They also said that I could not login because the online support was on a holiday and that’s why I could not login. I suggested that they put that on their website.
Very Frustrating looking for a driver that they should provide. I will not buy Belkin again.

Thanks Ben for working out the issue.

Cris Robinson said,

Hi i have an older top of the line Pfaff sewing machine Creative 2144/2170 and it connects to the computer trough a serial port, and I have used the Belkin cable on a XP laptop without a problem but this week the laptop died and i wasn’t sure if the machine program was going to work on my Windows 7 laptop, since Pfaff doesn’t support the 3D File Assistant, I found this post on Google and gave it a try, and it works perfectly, it is amazing how a company can sell you a item that costs thousands of dollar but don’t offer support for more than 3 to 5 years, because they want you to buy their latest programs that cost hundreds more, it would cost me almost $300 dollars to buy a new USB cable from Pfaff for my machine but this helped me so much thank you so much for this post !!!

I downloaded the driver as you suggested (from the MCT website), for my F5U109, and it now works fine with my new Windows 7 laptop. I have already successfully downloaded/uploaded my Honeywell GPS data today.

Ariel said,

Thanks, Ben!!! A research job well done!

After a contracted company installed our weather station, they left us with the Belkin F5U109 USB-to-Serial adapter. With all of our units running 64-bit, this driver is truly a wonderful find.

Again, your effort is much appreciated.

03/31/12 – YOU THE MAN! I hadn’t used my Etrex for several years so I’ve been fumbling around trying to get my old Garmin Etrex Vista to communicate with my Windows 7 OS, to no avail. Until I fumbled on your solution for the Belkin. I have the Belkin usb to serial f5u109. Your instructions worked beautifully. Just another reason to NOT support Belkin products. Thanks
Carlos said,

Thanks very much. I’m an FE that works on SUN and Cisco equipment and I depend greatly on having console session using my laptop. My XP Pro (32-Bit) crapped out on me and I’m borrowing a friends laptop – Windows7 64-Bit. First I had to deal with Windows7 not having hyperterm installed, once I figured how to add hyperterm I ran into the Belkin dongle not being supported until you saved me. Thanks again.
DG said,

Hi Ben

THANK YOU, THANK YOU, THANK YOU!!! My 60+ hubby is a refrigeration specialist who has just started working on chillers in the local hospital. He is not computer savvy and had become increasingly frustrated not being able to install the belkin driver on his new laptop. I’m more familiar with IT and used google to find your solution, downloaded the driver and installed it. When I showed hubby that the belkin device had been detected by his laptop – he was over the moon!!! Oldies like us are eternally grateful to IT guru’s like you who don’t give up until you find a solution, and THEN – you’re selfless enough to share it…you have a good soul…Thanks Again…

Worked for my Belkin F5U109′s as well.
Keep seeing this so often. A company (Belkin) licenses software and design from another company and then doesn’t pay for an upgrade from the licensor. This leaves us customers with useless dongles. Sadly, I’ve stopped purchasing Belkin after a few espisodes like this.

Already an owner of Belkin F5U109 since many years but needed to buy another adapter for the work. I bought the Staple model because there were no Belkin anymore.

The Staples USB to Serial software works well with Windows 7 x64. Besides, the Staple driver also works well with the Belkin F5U109. However, the Belkin hardware will be recognized as a Staple model.

Chris said,

OK got one for ya Delorme LT-40 GPS puck we storm spotters use the he77 out of these when tracking and delorme doesnt have a serial emulator for the usb for windows 7 anything and most of us are using 64bit. Lets see how good you are at finding that gem.
Benjamin Close said,

Not having the device it’s not an easy thing to find. However, after a few google searches I find it uses the cypress M8 serial chip:
http://forum.delorme.com/viewtopic.php?p=76051#76051 . Now looking at the linux driver we find “Supported microcontrollers in the CY4601 family are: CY7C63741 CY7C63742 CY7C63743 CY7C64013″ (http://cateee.net/lkddb/web-lkddb/USB_SERIAL_CYPRESS_M8.html). So it was off to cypress.com to look and the usb-serial chipset uses the CyUSB.sys driver which we find: http://www.cypress.com/?id=4&rID=40036 works under windows 7. Hence if you download the USB->UART controller (http://www.cypress.com/?rID=63794) and force it to install on the GPS unit, it *might* work. Good luck! PS: Either way if it does/doesn’t leave a comment here – and if it does work, a donation for a beer would be great

Thank you so much for this! I used the latest drivers from MCT’s website (http://www.mct-us.com/downloadfiles/U232-13.2.98.130315.zip) and it works fine with Win Vista 64-bit SP2. Please update your links as MCT has changed their website a lot. Also, a side note, the F5U409 shows up as “Staples Serial On USB Port” and the drivers support multiple USB ports without assigning a different COM port, a big reason I like the F5U409. Thanks again!

has anyone got these working for Windows 8? Looks like the driver needs to be different or edited to exactly match the hardware.
grrrr!

I had the same problem with the drivers not working on Windows 8. So after a bit of poking arounnd, I got updated drivers from here:
http://www.mct.com.tw/downloadfiles/U232-13.2.98.130315.zip

They work fine with Windows 8 64-bit.

Thanks a bunch. I hate throwing out hardware and this driver keeps my vintage Calcomp tablet alive on Win 7.
