At the request of Vojtech Pavlik, I'm forwarding this information to the usb-devel list. The problem is that my mouse/keyboard (both USB) are "freezing", usually when I'm switching virtual consoles. The message in the logs is this:
kernel: uhci-hcd.c: ef80: host controller process error. something bad happened kernel: uhci-hcd.c: ef80: host controller halted. very bad The usb info from dmesg is below. The machine is a dual pentium, supermicro P6DBE motherboard. Please let me know if I can provide any usefull information. -Michael ---------- Forwarded message ---------- Date: Mon, 7 Oct 2002 21:41:36 +0200 From: Vojtech Pavlik <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: keyboard/mouse "freeze" with uhci error in logs This is interesting.
