Problems with Prolific driver – Solution.

This entry was posted on Dec 08 2010
We are currently working on our Bachelor thesis where we are developing a TUI module for task status visualization. During this process we stumbled over a annoying problem with the Prolfic / LogiLink USB to serial (RS232) adapter which we wasn’t able to use on several Windows 7 computers resulting in the following error in device manager: “This device cannot start code 10 error”
After several hours of googling we found that the only driver working on W7 was the Windows Vista driver (v2.30) which can be downloaded from
Hope this saves all of you for a lot of wasted time :)

  1. Thanks a mil….can’t believe the Vista driver works for W7

  2. Thanks heaps, I spent days trying to get this to work on Windows 7.

  3. As a Newbie, I am always searching online for articles that can help me. Thank you

  4. Thank you, I have recently been searching for information about this topic for ages and yours is the best I have discovered so far.

  5. Great information! I’ve been looking for something like this for a while now. Thanks!

  6. When I try to install it, it tells me “For Vista only” and then stops. Still get “Code 10″. What am I doing wrong? Running 64-Bit Win 7 HE

    Cheers! Holg

  7. I haven’t tried to install the driver in an 64 bit version of w7 so I think that might be the problem. Try to run the installer in compatibility mode for vista or XP. That might help you out. ;)

  8. Thankyou for your solution.

    Greatly appreciated.

  9. you are a genius thanks a lot

  10. seems to be gone. Can’t find any drivers at the site you link to. :(

  11. @Peter : Thank you for telling us :)
    We have updated the link so you can download it directly instead – it is still the same as before, but since the site we were linking to isn’t online anymore we have posted the direct like instead.

  12. Thanks for this… Been ages looking for a driver to get my inforad working and this does it… Thanks

  13. Alamaja abrete la fajahana macalalaggaa!!! I would like to express my kindest gratitude for your post you saved my life men!!

  14. Guys, send me your mail adress and i will get you some belgian beers, you saved my day

  15. Thanks! Worked on 64bit Win7

  16. Haha, good one Olivier – spread the news about us instead, that will almost make us equally happy ;)

  17. This didn’t work for me, but I found a Win7 driver on the website of with a very low version number ( that did the trick for me !

    Over tge past few days I tried all the other drivers form version numbers,, to the latest but none worked

    You can download it here:

    Hope it works if the above mentioned drivers don’t work for you. Good luck !

  18. Yes, indeed there are a lot of problems with the Prolific drivers. Thats why I highly recommend a USB to Serial adapter with a FTDI chipset and drivers instead of Prolific. The FTDI chipset is 100% compatible with all versions of Windows 32/64-bit versions, Mac and Linux.

  19. Thank you!!!!

    FYI, this one works for my adapter: Dynex DX-UBDB9 Its about a foot long grey cable.

  20. Awesome. Sure did save me quite a few hours of scouring the net. Thanks a lot. By the way, I’m using Windows 7 Professional SP1 x86(32-bit).

  21. Nice job. this was the fifth driver i tried. windows finally accepted the new port. Perfect.

  22. Thanks, Thanks, Thanks

    My adapter works perfectly in XP, Win7 Ultimate, but not in Win7 Home on my new noteboook.

    This driver solve.


  23. Almost given up hope, fantastic!

    Very strange, yet it works even for Win 7 64 bit.

  41. If link is not avail than download the Prolific 2303 ver 3.0.1 for Vista, XP, and Win 7 (32/64) bit from V4e Drivers.exe.htm

  42. thanks worked for me on win7 after the non working prolific drivers were uninstalled

  43. thanks its works

  44. Installed the Vista driver(s) but unable to force the usb port to use it instead of the W7 driver which results in code 10. How do you make it use the Vista driver?

  45. After hours of frustration I found this post and it worked a treat on my Win7 system.

    Thank You

  46. Instale el el nuevo drivrs y no me funciona me dice que conecte el radio, no se que estara pasando en ni computador ya que lo instado y restalado y no funciona.

  47. Thanks – brilliant! This seems to have solved problem – now to make PDA synchronise…

  48. Hi friends,

    I had the same problem with Windows 7 64 bit. I had no connection to the radio. Have there been solved!

    Watching the connection between cable and radio. In my case the cable was not properly inside. Had to push even slightly to the right side so that it is pure.

    I just used driver for Win 7. Keep trying. Perhaps it is like mine, only the cable: D

  49. Wonderful, thank you!
    At last managed to connect a 10yr old Garmin Vista to Win 7.

  65. Thanks worked on Win7 64 bit. Had to run with Vista compatability and with admin rights.

    Windows tries to check online for new drivers, cancel the process and choose from installed drivers.

    Worked fine after that.

  66. It worked for me as well on W7. Many thanks!

  67. Worked for me on W7 64 bit. And on another usb – serial adapter I was just about to throw out.
    Your page was sent to me as a link with the replacement adapter from another supplier.
    How about a W7 driver for my HP5470 scanner.
    Many thanks for caring.

  68. Thanks soo much for this! you have no idea the frustration you have alleviated!! Helps run Power fc Datalogit on troublesome windows 7-8 platforms that refuse to see the the Datalogit when plugged in
