USB interrupt is turned off after periods of inactivity

Hi Nick (and the rest of LKML:)

I am seeing what might be a similar problem (usb interrupts get lost in relation to X), and in my case I lose my USB keyboard, which is very frustrating.

Looking at your output, I see some similarities between your system and mine. I am running Debian also, with kernel.org kernel 2.6.6 in my case. I am running unstable, and I suspect you are, too: this problem did not appear until I updated from unstable yesterday, pulling down the latest Gnome 2. Now, at the moment I log out of my Gnome session, and gdm restarts X, I lose my USB keyboard, and a similar message appears in the logs:

I'm running 2.6.6 on an Athlon XP 2800+, VIA K6 chipset. Silicon Image controller, SATA drives. Riva 128 video.

More info on the system in question (from /proc, lspci, etc) at http://www.uvm.edu/~jtl/lkml/usbprob/

In my case, I'm not using the Nvidia driver, or any other modules which would taint the kernel.

Hope someone can help....
