Date: Mon, 9 Apr 2007 16:29:41 +0200 From: Matthias Andree <matthias.andree@....de> To: linux-kernel@...r.kernel.org Cc: linux-usb-devel@...ts.sourceforge.net Subject: 2.6.21-rc6 USB Keyboard hangs (EHCI/UHCI/HID) Please Cc: me on replies, as I read linux-kernel sporadically and am not subscribed to linux-usb-devel at all. Greetings, I have seen my USB keyboard drivers lock up several times now with my M$ Natural Ergonomic Keyboard, both on SUSE 10.2's current kernel as well as 2.6.21-rc6 today. I don't ever recall this happen with older SUSE 10.0 kernels. The keyboard is connected to a USB2.0 hub with single transaction translator (at least that's what FreeBSD 6.2 says), which is connected to a via root hub. Symptoms are that the keyboard LEDs go off and no further input is impossible (I'm typing this into a PS/2 keyboard). Replugging does not help. Trying to unload ehci-hcd hangs modprobe, and additionally I've got a stuck khubd (not sure if that's related), else no logging. I'm rebuilding the kernel with HID/USB debugging cranked up to see if I can get some detail out of the situation. Any specific kernel debugging options that might help me debug this further?
