Acer 5920G Usb bandwidth Problem?

Hello once more. Well my main problem is that if i connect more than 2 usb flash disk on this lappy then the transfer rates are very slow (from 20Mb/s they drop to 5~9Mb/s). Exactly the same happens if i connect an express card ssd hard disk. Both the ssd hard disk and the usb floppy loose a lot of speed. I have try to connect the usb flash disks (4 of them all of them different brands) on all of the usb connectors with the same bandwidth dropouts.

In Device Manager i see the usb flash connected on different host controllers and different hubs and the bandwidth on every host controller is less than 20%.

Anyway i am still trying to figure out what the heck is going on but i am quite eye blind here

 

Hmmmm....try to update your Intel chipset drivers(Intel INF)

 

Thanks for the reply. I did that right now with no success at all. If i connect more than one usb devices or a usb with an express card flash disk the read and write times goes up.

Lets say if my usb flash disk can read and write 20Mb/s if i connect a second one it goes max at 6Mb/s to 8Mb/s.

If i connect my usb television card and together a flash disk and start transferring data to the usb while i watch tv i get tv sound cuts.

I am using windows vista x64 but i had exactly the same problem with x32...
