The USB interrupt is indeed shared, but with my SCSI adapter and ethernet card:Hi,On Mon, Jan 20, 2003 at 11:37:51PM -0500, Simon M. Arthur wrote: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.
Just a wild guess: You use the same interrupt for ohci/uhci and the parport? Check /proc/interrupts. You should be able to change that in your BIOS. Bye, Henning
[root@blossom chroma]# cat /proc/interrupts

Note that the parallel port isn't listed.
I messed around with the BIOS a bit, but it doesn't let me assign the USB interrupt directly. I did change the parallel port to use IRQ 5, but still have the same problem when printing.
Thanks,
Simon
