Not sure whether this is a kernel, hotplug, or usb question. Beginning somewhere in the 2.6.5-rc1-mmX series, all my usb devices are apparently disconnected during the boot process -- they are detected but subsequently made inactive. Post-boot lsusb output shows them still attached, but all are nonfunctional. Unplugging and reconnecting them produces no log output and doesn't make them functional. Kernels in the Linus tree up to and including 2.6.5-rc1-bk4 are fine, but 2.6.5-rc2 displays this behavior as does 2.6.5-rc2-mm1.
Trying to rmmod ohci_hcd or ehci_hcd results in a hung process. So does an attempt to restart hotplug. Booting the computer with no usb devices attached and then plugging them in later results in usable devices, but attempting to rmmod ohci_hcd at that point just produces a hung process again. So I'm a little suspicious about the interaction between the kernel code and hotplug and/or coldplugging. I'm using a Shuttle SN-41G2, FN-41 mainboard, nForce2 chipset including of course the onboard hubs. Happy to turn on debugging, post logs, versions, and configs, try patches and so on.
