I've read about similar problems in other threads, but I can't get anything
to work.
My problem: I have a USB2 scanner. When I plug it in and turn it on I get a
message stating: "This USB device can perform faster if you connect it to a
Hi-Speed USB 2.0 Port. For a list of available ports, click here."
I click on the message and it lists "USB Root Hub" with 8 ports available.
My computer is an MSI K8n Neo motherboard and has 8 USB2 ports, 4 on the back
and two USB connections on the motherboard (JUSB1 and JUSB2) for putting
extra ports in the expansion slots. I have that cable hooked up. No matter
which port I plug into (any of the 8 I have available) I get the message.
In Device Manager under Universal Serial Bus controllers I have the
following listed:
Standard Enhanced PCI to USB Host Controller
Standard OpenHCD USB Host Controller
Standard OpenHCD USB Host Controller
USB Root Hub
USB Root Hub
USB Root Hub
When I go into properties for the three USB Root Hub entries and select the
Power tab I get (from top to bottom) 4 ports available, 4 ports available, 8
ports available. Of course that's with the scanner unplugged.
I have an internal USB2 card reader that plugs into the JUSBx port on the
motherboard. When I plug that in to the JUSB2 connection it adds a "USB Mass
Storage Device" into the list and it shows up in the first USB Root Hub under
Power. If I plug in my printer (Canon S9000) into one of the back USB ports
it shows up in the first USB Root Hub under Power and a USB Printing Support
entry shows up under USB Controllers. When I plug my scanner in after these
devices I get different messages depending on which port I plug into. If I
use the back ports it says the same message as above, that I need to plug it
into a hi-speed port. If I plug it into one of the ports supplied by JUSB1 it
says "Unknown Device" and that it's not functioning properly.
Any clues? I have tried turning off all USB devices and uninstalling all
the entries under USB Controllers and then restarting. They all come back.
But it doesn't help.
Of course this used to work, and I haven't changed anything. Seriously, it
used to work yesterday and today it doesn't. The Card reader is always on (as
it doens't have an off switch) and the printer is left on also. The scanner
is turned on when necessary. Taking the printer and card reader out don't
help. I have also tried disabling each of the USB Root Hub's in all
combinations and either the scanner isn't recognized at all, or it gives me
the message that I need a hi-speed port.
Thanks,
Scott
