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.
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:
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.
