*For Microsoft Windows Vista (and windows 7) Click Start, and type device manager in the Start Search box. Click Device Manager in the Programs list. If you are prompted for an administrator password or confirmation, type your password or click Continue. In the Device Manager dialog box, expand Universal Serial Bus controllers. Right-click USB Root Hub and then click Properties. In the USB Root Hub Properties dialog box, click the Power Management tab.

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 reedit, 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.
