When trying "ifconfig usb0 IP-address", I get in syslog:
... usb0: register usbnet at usb-0000:00:1d.0-2, Prolific PL-2301/PL-2302 usb0: open reset fail (-32) usbnet usb-0000:00:1d.0-2, Prolific PL-2301/PL-2302
I think the right answer is just a patch to ignore open reset failures. Thing is, some Prolific chips seem to require it, others seem to fail it. Lacking information from Prolific, we can't do better.
Does patch this help?
