On my USB keyboard/hub combo, the keyboard wasn't working, but I plugged a mouse into the single hub port and the mouse worked.
By 'keyboard wasn't working' I mean this: ~~~~~~~~~~ [root@gargoyle 2.5.46]# modprobe hid drivers/usb/core/usb.c: usb_device_probe drivers/usb/core/usb.c: usb_device_probe - got id input: USB HID v1.00 Keyboard [API API USB KB HUB] on usb-00:1f.2-1.1 drivers/usb/core/usb.c: usb_device_probe drivers/usb/core/usb.c: usb_device_probe - got id drivers/usb/core/hcd.c: giveback urb f7ca2680 status -32 len 0 drivers/usb/core/hcd.c: giveback urb f7ca2680 status -32 len 0 drivers/usb/core/hcd.c: giveback urb f7ca2680 status -32 len 0 drivers/usb/core/hcd.c: giveback urb f7ca2680 status -32 len 0 input: USB HID v1.00 Device [049c:0002] on usb-00:1f.2-1.2 drivers/usb/core/usb.c: registered new driver hid drivers/usb/input/hid-core.c: v2.0:USB HID core driver ~~~~~~~~~~ I had usbcore, uhci-hcd, and hid loaded as modules.
