Dear All,
I need your help. Following are the facts of the case in seriatim, to
facilitate in easier understanding of the situation:
1. You see I have Vista OS installed on my PC.
2. My PC has 4 USB ports on the rear-side, which I know for sure are USB 2.0
Hi-Speed Ports. Before facing this issue, I could connect any Hi-Speed USB
device to any of these ports and have data transferred at high speed rates,
normally.
3. Yesterday, I had attached a cheap Chinese-make USB hub to one of those
rear ports. The device installed itself quite normally and messages to the
effect that drivers for the same had been installed, were given.
4. Soon after I had removed the USB hub and had my 8GB pendrive attached to
the same USB port, I was given a message which stated that "the device could
perform if I had connected to a higher speed port".
5. Despite umpteen number of reboots, shutdowns, uninstalling of USB devices
from the Device Manager, etc., all the 4 rear-side USB ports behave as if
they are USB 1.1 type ports only.
6. Incidentally, the Device Manager displays that there is an enhanced USB
host controller.
Please help as to how I could have them revert to their normal USB 2.0 format.
Thanks in advance.
