System Profiler reported a vendor ID of 0x0557 and product ID of 0x2008. Accordingly, I edited Info.plist for ProlificUsbSerial.kext (setting them to 1367 and 8200), kextloaded it, and got /dev/tty.usbserial. Joy! Sadly, reading from it results in no data ever (and indeed a hung dd if=/dev/tty.usbserial bs=1.

So, I booted into Ubuntu, and tried lsusb -v, which reported 0x067b and 0x2303. Those are 1659 and 8963, the values originally in the kext's Info.plist(!). I think I'm even more confused now.

Ubuntu and the wireless card still won't play ball.

Which is, incidentally, what my one of these devices says under Fedora. Makes sense really given that the chip is called PL2303. 0x0557 seems to be ATEN which is another compatible device although I've no idea why one device could have two completely different identifiers.

Did you come across this on your googles? http://www.versiontracker.com/dyn/moreinfo/macosx/29998

That creates two /dev entries, neither of which does much of use. the /dev/tty.PL[thingy] AFAICT doesn't open usefully, and the /dev/cu.PL[thingy] is similarly not-very-good (returns an error, or splurges garbage over the screen, depending on what you try and open it with).

Thankfully, I've managed to get ubuntu talking to the wireless, so I think that's going to be the way to go.
