Hi, i'm using a sid and have noticed a strange problem with usb on kernel-image-2.6.8-686 and kernel-image-2.6.8-686-smp on my computer.
It seems that only the devices that are plugged before the uhci_hcd module is loaded are detected. These are working properly, but if I plug another device after, it doesn't even appear in /proc/bus/usb/devices, and idem if i unplug/replug one which was working properly. Worse, if i try to unload uhci_hcd, the system is freezed, and need a hard reboot. I tried under 2.6.7, and have no problem. I also tried to disable hyperthreading but the problem is still there. So my motherboard is an Asus P4P800 Here's some pieces of a lspci : 0000:00:00.0 Host bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02) 0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (rev 02) 0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (rev 02) 0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02) 0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (rev 02) 0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02) I don't know what information could be useful, so if you need more, just ask me, i'll be glad to help. Thanks, Boris.
