The same thing happens with different brands of Prolific devices!
This is sounding like a hardware problem on the device you have plugged
into the usb-serial device. Are you sure that works?
I have now ordered a FTDI device to see if anything changes! (hope)
I hope so too :)
thanks,
greg k-h
now this is the actual situation:
i've 4 different kind of usb-serial devices, 3 PL2303X (different
brands) and 1 FTDI
(ubuntu 8.04) with kernel 2.6.24 works with all 4 devices
(ubuntu 9.10) with kernel 2.6.31, 2.6.32, 2.6.34 works only with ftdi
I think there is a bug on recognizing the PL2303X device,
to solve the problem, I would be happy to give you more details if necessary
thanks
