USB

Some USB devices are not APM/ACPI friendly and may not operate properly
after resuming from Standby or Hibernation. Test the attached USB device
after performing each step.
1. Verify that a USB port and an operating system with USB support are being
used to attach a USB interface external device to the system.
2. Verify that USB is enabled in BIOS.
3. Verify that the USB device and any required drivers were installed in
accordance with the manufacturer's instructions.
This may require removing the USB device and the drivers, and then
reinstalling the USB device and the latest drivers.
4. Verify the USB device works on another machine, if available.
5. Verify another USB device, if available, works on this machine.
6. Verify that the USB device is USB 1.1 or 2.0 compliant.
Plugging specific USB 1.1 compliant devices into a USB 2.0 compliant port
will cause that the device should function normally, but at a slower speed
than if a 2.0 device is attached to 2.0 port. Most USB 1.1 devices will
function normally in USB 2.0 ports.
7. Verify that external power is attached if required.
Some USB 2.0 devices will require additional power from external sources
or an additional USB port to function correctly in USB 1.1 compliant
computers.
