IrDA USB-Serial Controller driver

Published September 12th, 2005

I’m looking at learning Java, so I can use J2ME to write apps for my mobile phone. To this end, I bought an IrDA (infra-red) dongle for my PC so I could connect directly for transferring files, debugging etc. It arrived this morning, packaged up in one of those really hard-to-open bubble packs. I ended up attacking it with a pair of scissors and (I don’t know my own strength!) cutting a chunk out of the driver CD.

D’oh.

Of course there were no identifying marks whatsoever on the dongle, the CD or the packaging to tell me who made this device or even what it’s called — Windows identified it as a ‘USB-Serial Controller’. Anyway, I tried the mangled CD in my drive (at work, because I don’t care if it breaks my work PC!) and although I couldn’t get at the files, I did at least see enough to identify the dongle as an MA620. A good deal of searching around and I found a zip file with what looked like the necessary files. I installed, restarted, popped the dongle in and bingo!

I found it quite hard to locate the drivers so I decided I’d stick them up here for anyone else who finds themselves in a similar situation. Here’s the file:

MA620driver.zip

Disclaimer: the drivers worked for me, but I make no claims that they will do so for you (and don’t ask me to help you if they don’t). I take no responsibility for any damage or malfunction caused by the files — I just downloaded them from some file service somewhere.

Update: Apparently this page is highly-ranked on Google for ‘usb to serial controller’ so if you’re looking for a driver for a USB->serial port cable, you might find this file helpful (thanks to ‘Alex’ for the heads-up on this). As with the other file, don’t blame me if the above does nasty things to your PC…

Update again: Alex also sent me this file, which he says helped him get his USB->serial port cable working. The usual disclaimer applies.

Good luck!

    Do you plug the dongle in before or after installation?
    thanks

  3. Stickman on December 13, 2005

    I installed the software first, then plugged the dongle in after restarting Windows.

  15. Ivo on June 23, 2007

    THANK YOU!!!! I bought a GPS which has to be connected through Hyperteminal and I couldn’t connect it because my pc would not recognize the port until I found the driver in your website! THANK YOU x 100!! :) excelente samaritano!

    More crazy than the rest, I just lost my little CD. It has to be here somewhere, but after a HD crash I had to find a way to get my cable working again – short of buying a second one.

    What gives me some hope – and I am adding it here because google only sent me to sites I cant read (asian, and other unknown fonts) is the device instance ID which can be found in the files sent by alex (which seem to be the same file, but with different names)

    Device ID: USB\VID_067B&PID_2303 and more, but for google – repeating as seperate “words” because google likes that: USB VID_067B PID_2303

    Sure hope it works!

  18. mike on January 28, 2008

    a bit a latecomer, a bit an outdated technology, but it happened to me just the same. IrDA dongle, no-name-product, dubious sources (“handbook” written in CHINESE or whatever…) only that the driver-CD was not cut, but scratched and un-readable. so i googled around and found your site. and – the software works perfectly! thanks a lot!

  20. Pixelsplasher on October 15, 2008

    Thank you. The DX-UBDB9 USB Driver worked for the cable that is for connecting my Sony Ericsson K508c to my PC.

  21. Udayakiran on November 10, 2008

    Thx a lot… u saved my life… i didn’t want to use driver guide because i had to pay $3 for the thing and its much more than its actual price…

  22. puttnampete on January 3, 2009

    Thanks mate, I almost payed $35 for software that did not hava a working driver !!! you not only saved money but valued time…worked 1st time on reboot…cheers

  23. ekcider on March 19, 2009

    I am running a vista hybred labtop and lost my dynex driver cd I had the computer redone because I couldnt stand vista, now it runs great but geting all my applications running again has been a challenge. The latest driver update you provided works great and was easy to load thanks very much.

  24. sheva29 on April 3, 2009

    Thanks, dude! Very useful, it works well. You’re my hero!!!

  25. Kubik on April 4, 2009

    Some drivers for Prolific USB-RS232 bridges can be found on the manufacturer’s web:
    http://www.prolific.com.tw/eng/Download-2.asp?ID=17

    It looks like VID_067B identifies Prolific, while PID_2303 (or whatever else) specifies the chip used. The Prolific drivers seem to have WHQL signature so I prefer those :-)

    And – thanks to Stickman, his article kicked my lazy butt to find real drivers :-)

  26. rick on April 15, 2009

    The ‘Update Again” file worked for me for an unkown USB to serial adapter I had.

    Even better, it worked under Windows 7!

  27. j on September 16, 2009

    omg thank you so much!
    those prolific drivers (USB2Serial_Drivers-Dynex) fixed everything for me!

  28. Jason on October 13, 2009

    Thanks so much! The USB to Serial drivers link worked like a charm!

    Cheers!
