Usb To Pc Connection Has Stopped Working

[Don Miguel]

Suddenly, USB to PC connection has stopped working.
Now i use FLASH CARD reader to test / load stuff

it is very annoying. I haven't uploaded anything new, haven't updated FW / etc.

Has anyone met such a problem?
Could it be a windows problem? (all the rest USB devices do work)

So what happens when you plug 2x into pc?

nothing happens...

there's no "unknown usb device found" message

This has happened to me too. Neither Win XP or Kubuntu see the device, nothing comes up. Used a different lead, port, plugged other devices into the pc and they are detected.
I have no idea what to do next. Any advice would be appreciated.
