The light on the backside stays dark. /var/log/messages says: Dec 31 20:43:37 laptop kernel: usb 2-1: control timeout on ep0out but this works in the 2.4 kernels. With -rc1, the system locked solid when the usb_uhci driver got modprobed. No keyboard input, no disk activity, and when re-inserting the USB mouse (which is enabled by BIOS at reset), the light remained dark. I saw the first 3 or 4 lines about detected hubs before it froze, but I don't have those lines in my system logs. I only remember they were very similar to lines from my 2.6.0: Jan 2 09:57:01 laptop kernel: uhci_hcd 0000:00:1d.1: UHCI Host Controller Jan 2 09:57:01 laptop kernel: uhci_hcd 0000:00:1d.1: irq 10, io base 00001820 Jan 2 09:57:01 laptop kernel: uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 2 Here's what lspci -v has to say about the controllers: 00:1d.0 USB Controller: Intel Corp. 82801CA/CAM USB (Hub #1) (rev 02) (prog-if 00 [UHCI]) Subsystem: IBM ThinkPad A/T/X Series Flags: bus master, medium devsel, latency 0, IRQ 5 I/O ports at 1800 [size=32] And two more near-identical entries with IRQ10, io-port 1820 and IRQ10, 1840.
