My USB is currently 'broken'...
I have a Via Epia MII10000. It has 2 USB ports on the back and I bought an USB hub which allowed me 4 ports. The hub is unpowered and has 2 USB cords going to the CPU, I assume for power.
Connected to the hub I have: GPS, WiFi, Touchscreen, and a USB extension cord for connecting memory sticks.
Recently the USB just stopped working after a reboot... My GPS mouse doesnt light up, my touchscreen doesnt work, and my WiFi doesnt work.
I connected the tocuhscreen and GPS directly to the onboard USB.. Neither worked. When I connect the hub to the onboard USB, the hub's LED lights up but as soon as I connect a device to the hub, the light dims, and if I connect two devices, the light essentially turns off. I dont know if it always did this or not.
Could I have connected too much to the USB and burnt it out? I say no because the mobo has an onboard connector to add 2 more front panel USB ports... I think. If I did burn it out, is there a fuse? Where?
Is there an option in BIOS to turn the USB on/off? I havent checked. Maybe it got turned off.
