i got toshiba notebook and since i reinstalled vista it goes with my usb like this.
On the right side i got 2 usb and there works only 1 of my usb flash discs.
On the left side i got one usb and hdmi/usb combo. That hdmi as usb doesnt work at all and another usb takes only my mouse.
I tried there like 10 usb flash discs and it gives dialog like:
,,u need to check disc first,, and when i click anything it doesnt make any action. Doesnt even appear in ,,my computer,,.
