I have a vostro 1510 running Windows 7. My LT has 2 usb ports on the left and 2 on the right. Sometimes I get messages saying a device will run raster if plugged into a usb2 port instead of a usb1 port. But I can't tell which is which - sometimes I get that message when plugged into the right, sometimes the left.
Looking in Device Manager, I see 7 (yes seven) instances of USB Root Hub and 7 of Intel (R) ICH8 Family USB Universal Host Controller - nnnn. (Where nnnn = 2830 to 2836, or 283A).
Can anyone tell me how to know which ports are USB2 type? And how much speed difference does it make anyway?
Many thanks
Richard
