Hi

I have been using the AT91SAM9263-EK boardwithout incident for a while. Today I tried to download software using SAM-BA v. 1.11. After a reset, the USB connection (which connects and disconnects on each reset) suddenly came up with "USB Device not recoginzed". Since this, I have been unable to re-establish USB connection with the board. Serial connection via COM1 works fine, but is not an option. This is what I've tried:

* Uninstall the device, then re-attach it.
* Update the driver (found atm9264.inf/.sys on the web)
* Uninstall/reinstall SAM tools

Any ideas how I can bring the USB connection back to life?

Best,

Troels
