Hello, I have an usb hub built into my monitor. It is being disabled when the monitor is turned off and reenabled when it's switched back on - in theory. However, this doesn't seem to work. Attached below is the relevant kernel output in the hope that it will be useful to someone who knows. Kernel is 2.4.5-ac21. Regards, -Udo. usb.c: registered new driver usbdevfs usb.c: registered new driver hub PCI: Found IRQ 9 for device 00:04.2 PCI: Sharing IRQ 9 with 00:04.3 PCI: Sharing IRQ 9 with 00:09.0 PCI: Sharing
