Hi there. I plugged a usb hub into the usb port of my laptop. Something went wrong and I had a short circuit. (At least it sounded like it). The machine went off (i guess as protection). When I rebooted it the system was not able to recognize the usb ports  (it marks it as unknown device. I have two usb ports). Temperature went higer (about 10 degrees). If I plug a usb device into the upper one the machine freezes and I have to turn it off. The rest seems to be working fine. Is there anything I can do to fix it? Can I work around this problem by using a PCMCIA usb hub? Do you think I will have to change the board to correct the problem?
Tnx

looks like the short fired the usb ports, so you would need to replace the motherboard to fix it or as you staed use a pcmcia usb card as a work around.

There are lots of workarounds, including a hub to the working USB port and to answer your question, sure, you should be able to use a PC Card USB adapter to add more USB ports (and by the way, the correct term is "PC Card" and not "PCMCIA Card").  But to really fix the problem, you are probably looking at a new motherboard (OUCH!).

USB Ports are short-circuit protected. Each port is limited to 100mA for low power devices and 500mA for High Power devices.

As of my experience, I got Message " Usb device over current status detected. System will shutdown in 15 seconds" on my ASUS Motherboard, when i accidently shorted Pin1 & Pin4.

Under Windows 7 you can go to Device Manager>USB controllers>USB root Hubs.
Now, Go to properties of each root hub, under Power tab you can find total available power on each port.
