Inspiron 600m USB ports not working - Hardware problem
My laptop's USB ports are no longer working. I believe that some internal circuitry got fried after I plugged in a USB powered device that had its own power supply. I don't remember exactly what I did because it was while ago. I still like to use the laptop, but without USB its uses are quite limited.
When I plug in a device, nothing happens. It is neither powered nor recognized. All USB ports are affected.
If someone has an idea what might have caused this and how to fix it, I would greatly appreciate it.
