I'm working with a PL2031 Prolific USB-USB Bridge cable on a 2.2.16 kernel with
the 2.4.0 USB backport patch applied and USB-OHCI. However whenever I try to
load the plusb driver I get an oops message:
plusb.c: plusb_init
usb.c: registered new driver plusb
plusb.c: plusb: probe: vendor id 0x67b, device id 0x0 ifnum:0

This is the only device that gives me any problems. Both my usbmouse and
keyboard work fine. Also the device driver loads fine when the cable is not
plugged in but as soon as I plug the cable back in I get an oops.
Any help is greatly appreciated.
