Device works perfectly - though has naming problems about osx-pl2303 HOT 7 CLOSED

The suffix (the bit after "tty.PL2303-") is generated from the serial number stored in the device, so I guess this means your device(s) have corrupt or badly formatted serial numbers. Check in "USB Prober" (installed with Xcode) or "System Profiler" if the serial number for the device looks wrong?

I've just checked all my PL2303 devices and none have a serial number set. In this case, the driver creates a suffix from the USB port number/location.

If you're a programmer, I'd suggest fixing the code around lines 986 to 1004 in osx_pl2303.cpp - it's supposed to reject serial numbers that aren't valid ASCII, but in your case it's obviously not doing that properly.

I just uploaded a version with a hack that bypasses the serial number logic and always uses the location info for the suffix. Hope this helps.

Thanks - but it still does the same thing.

The USB Probe indicated that the serial number is 12345678, with no cruft on the end. Looks like the rest of the string is uninitialized buffer, as the device special seems to have random characters after the string.

The device I'm playing with is the ultra-cheapo MS Streets & Trips GPS that came with S&T 2008.

Try the one I just uploaded.

It seems to be identical to the 13 Dec version.

I added a line of code to clear the buffer and make sure it's correctly terminated. Try again - I uploaded it again in case I accidentally uploaded the wrong file. Sorry for this back-and-forth, but I have no way of testing this (as I said, my devices don't have serial numbers).

Same device name issue as before, sorry. Is there any easy way that you can prevent non-alphanumeric characters getting into the device special name?
