Hi guys,
When I add support for USB ("uhci" and "usb") and USB Mices ("usm") without
including the "ether" pseudo device and compile the kernel, I get this error:

If I add Ethernet support (by adding the "ether" pseudo device) the kernel
compiles fine. I find it odd that USB support depends on support of Ethernet,
because as far as I'm aware the basic USB devices ("uhci" and "usb") and the
USB mouse device has nothing to do with ethernet support. Is there any
particular reason why this is happening?
