my Microsoft wheel Optical USB mouse works well in arch0.6 (with kernel2.6.3), but after I update kernel to 2.6.9-ARCH, my mouse device can not works. The red LED have no light.
But when I install kernel2.6.9 which compile by myself, the mouse works well.
arch kernel 2.6.9 got no built in usb support,
you have to load the modules yourself or use hotplug,
if you compile your own kernel you can compile it with built in usb and your mouse will work witout doing anything more,
arch + gentoo + initng + python = enlisy
Does it means the uhci-hcd & ehci_hcd support in new kernel-2.6.9-ARCH which is compiled by arch official is built in moduiles instead of kernel-core (vmlinuz) ?
Yes, they're modules. This is easy to determine by inspecting /boot/kconfig26:
