Hi, starting with gentoo-sources-2.6.15-r1 i observe the following behavior: when booting the machine with a connected usb keyboard, everything is fine. when unplugging and again plugging the usb keyboard, it is not detected and the following is printed in the kernel log: [17188938.436000] usb 1-1.2: USB disconnect, address 8 [17188938.436000] usb 1-1.2.1: USB disconnect, address 9 [17188938.436000] usb 1-1.2.3: USB disconnect, address 10 [17188959.240000] usb 1-1.2: new full speed USB device using uhci_hcd and address 11 [17188959.348000] hub 1-1.2:1.0: USB hub found [17188959.348000] hub 1-1.2:1.0: 3 ports detected [17188959.660000] usb 1-1.2.1: new full speed USB device using uhci_hcd and address 12 [17188969.764000] drivers/usb/input/hid-core.c: timeout initializing reports [17188969.764000] i can make it work, though - by using the keyboard which is on my laptop, (pressing some buttons).

Please reproduce in the latest development kernel (currently 2.6.16-rc4)

Please test gentoo-sources-2.6.15-r6 - it should be fixed there.

gentoo-sources-2.6.15-r6 does not work either.... best regards
Thanks for testing. Guess we'll just wait for 2.6.16...
gentoo-sources-2.6.16 is now in portage.
