power management as follows:
- In the Start menu, type
DEVMGMT.MSC (and press the Enter key) to display Device
- Click View and select "Devices By Type".
- Expand the Universal
Serial Bus controllers section of the tree
- Right-click each USB Root
Hub entry, then select Properties.
- In Properties, select "Power Management and uncheck
"Allow the computer to turn off this device to save power".
- Restart your computer.
