It went away sometimes with the 2.6.7 - 2.6.8 kernels and surfaced now again with 2.6.11. Its a USB Card reader connected to an onboard USB connector, which sometimes fails to initialize properly. If it for some reason fails to initialize, it will continue to fail on consecutive reboots / cold starts. And once its failed to initialize, the only solution I have found is to unplug the onboard connector and reconnect it while the computer is running. This will make it initialize correctly, and it will also continue to initialize correctly after reboot / cold starts. I know this probably sounds like a HW-problem with the card reader, but I thought Id post the dmesg logs showing the messages when I unplug the cardreader and replug it while the computer is running. It might possibly give some clues if this is a flaw in the kernel or HW. (There are actually two onboard USB connectors, so that is the reason why in the logs below its sometimes shown as usb2 and sometimes usb3 depending on what port I plugged it into - I tried both). Also, one practical question. If the cardread fails to initialize, is there any way I can try to reinitialize it without physically unplugging/replugging the onboard connector? Its not very practical opening the case each time this happens... Thanks for any feedback! -Frank Aune PS: Please CC me as Im not on the LKML. ------ >>From dmesg after boot: usb 2-1: new full speed USB device using ohci_hcd and address 2 usb 2-1: khubd timed out on ep0in usb 2-1: device descriptor read/64, error -110 usb 2-1: khubd timed out on ep0in usb 2-1: device descriptor read/64, error -110 usb 2-1: new full speed USB device using ohci_hcd and address 3 usb 2-1: khubd timed out on ep0in usb 2-1: device descriptor read/64, error -110 usb 2-1: khubd timed out on ep0in usb 2-1: device descriptor read/64, error -110 This is where I start unplugging and replugging the cardreader.
