USB Hub unexpectedly powers down in sleep mode
Is this a Win 7 64 issue because:-
I have two Toshiba Dual Core Celerons, one runs Win 7 32 and the other Win 7 64.
The 32 bit OS works perfectly and keeps the USB hubs powered up during sleep. The 64 bit OS needs an HID connected directly to the PC to stop the hub being powered down.
There are other posts about the same issue on HP's on this and other forums and it always seems to be related to Win 7 64.
With my two PC's I have checked to make sure the BIOS, Device Drivers and Power Plans are the same.
Am I ever going to get this (power to the USB hub in sleep) to work on the 64 bit OS?

First Post -----------------
My laptop has 2 usb ports.
If a mouse or keyboard are plugged directly into one port on the PC the hub on the other port remains powered in sleep mode.
If there is no HID plugged directly into the PC, OR, hubs on both ports - the hubs are powered down in sleep mode even though I have un ticked all the "Allow the computer to turn off this device to save power" in the device drivers.
What do I need to do so two hubs remain powered in sleep mode?
