[Linux-usb-users] Need help with mouse problem

[Simon M. Arthur]

I have a Kensington USB mouse and a parallel port printer.

Every time I try to print, the light on my mouse goes out and it no longer responds.

Some relevant information:

[root@blossom chroma]# uname -a
Linux blossom 2.4.20 #2 Sat Jan 18 03:56:55 EST 2003 i686 unknown

As I am about to print:
[root@blossom chroma]# tail -f /var/log/messages
Jan 20 23:23:01 blossom kernel: parport0: PC-style at 0x378 [PCSPP(,...)]

Jan 20 23:23:08 blossom kernel: hub.c: Cannot enable port 1 of hub 1, disabling port.
Jan 20 23:23:08 blossom kernel: hub.c: Maybe the USB cable is bad?


If I unplug and replug the mouse, the light comes back on and it seems to work fine again:

I have also tried the "uhci" module, with similar results.

Any solutions or workarounds you could provide would be greatly appreciated.
