Method 2
*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.
You might want to disable
this feature for server products where power management is not important or
required.
*To disable the Selective Suspend feature, follow these steps:
Click Start and then click Run.
Note If you are running Windows Vista,
click Start, and then use the Start Search box.
Type regedit, and then click
OK. Registry Editor opens.
Locate and then click the following registry
subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\USB
If the
DisableSelectiveSuspend registry entry is present, double-click it. If it is not
present, create the entry. To create the entry, follow these steps:
On the
Edit menu, point to New, and then click DWORD.
Type DisableSelectiveSuspend,
and then press ENTER.
On the Edit menu, click Modify.
In the Value data
field, type 1 to disable the Selective Suspend feature, and then click
OK.
