I downloaded the kernel from git clone
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git.
and git pull. Compiled without changing any default parameter.
Kernel boots up find the usb devices. The lights are up for the mouse
and keyboard. But I can't use them. So I unplug the hub and reconnect
it. The following is the low.
The hub, mouse and keyboard are disconnected first. Kernel find the
device. Does the "uevent" actually disable the device? Is there
something I need to fix in the kernel?
