Problem Ideapad y510 USB Port

[agahb]

My Ideapad Y510 has a big problem.

Only 1 (of 3 USB ports) is working perfectly, the others 2 are working too slow... i'm using the windows 7... does anybody knows what is happening?!?

thanks !!!

try to install intel chipset.

by the way, did your lenovo come with windows 7 or windows vista?

I found that everything works better if you turn off the USB compatibility in the BIOS. I doubt any of your stuff is USB 1.1

make sure you're running usb 2.0 supported device.

Of course I know that.

 I tested a kind of device on the 3 doors of my Y510, just one works fine (as 2.0), the others 2 works terrible... very slow (1.1 probably)....
