JSI Tip 8292. If you plug in a USB device immediately after Windows XP comes out of standby, or hibernation, the device is NOT recognized?

The subject behavior occurs because when waking from the s3 (Standby), or S4 (hibernate) power saving state, your computer may need 5 to 10 seconds before the selective suspend feature of the USB driver stops interfering with new hardware detection.
NOTE: The timing depends on a number of factors:
Host controller hardware.
Attached hubs.
Attached devices.
USB driver versions.
USB 2.0 support.
Other hardware / configuration variables.
To workaround this behavior, use any of the following:
Wait 5 - 10 seconds before plugging in the device.
Unplug the device and plug it back in.
Use Device Manager to Scan for hardware changes.
Start / Run / Devmgmt.msc / OK.
Use the Action menu to Scan for hardware changes.
Close Device Manager.
