----------------------------
A device may not establish a connection with a desktop computer

an external USB port hub in Windows XP or in Windows Server 2003.

Proposal for solution from Microsoft:
-------------------------------------
You can disable the USB Selective Suspend feature as a workaround
by editing the registry.
The USB device may become unresponsive because of a race condition
in the Selective Suspend feature.
The Selective Suspend feature suspends the USB device to
efficiently maintain battery power by enabling the computer to
turn off the USB device.
However, sometimes this feature may not correctly wake up the
USB device.
Therefore, the USB device is unresponsive when you try to use it.

Applies to:
-----------
Windows XP Professional
Windows XP Embedded
Windows Embedded Standard 2009
