Unknown problems with USB devices.

Dell

Dell has stated in Dell knowledge base document FA1021802, that a USB device such as a scanner or printer may not be detected or function correctly when connected to the USB port of a Dell Latitude or Inspiron PC (it may occur on other models as well).

Various communication errors may occur, including device initialization and device not found errors.

Some Dell computers do not provide enough voltage from the USB ports to power some USB devices.

Dell recommends purchasing a powered USB hub to provide the USB devices with enough power to operate correctly. A USB keyboard with built in hub is not a solution and can worsen this problem.

Dell Inspiron 2650 has a known issue with the onboard O2Micro cardbus controller. Problems with cards attached to the controller are resolved by a patch found here

NEC NX series

NEC NX series computers are equipped with a Legacy mode USB BIOS that allows the USB keyboard to work in real-mode. After suspending and then resuming the computer, or waking up the machine by using a USB keyboard/mouse, USB devices will not work after the computer is resumed.

This phenomenon is known as Plug/Unplug. Unplug the USB device that is not responding, wait 30 seconds, and reattach the device.
