AT91SAM9G20-EK not showing up in windows 7 device manager

Wed Sep 23, 2015 2:12 am

Hi,
I have not been able to get my AT91SAM9G20-EK recognized by Windows 7.
I have opened jumpers J33, J34, J7, connected the serial DBGU cable to the PC, connected the USB A/B cable to the PC, downloaded the SAM-BA 2.15. When I run SAM-BA, the box comes up but I cant select a connection to the AT91.
In the device manager, there is no item that would look like the AT91: no 'unknown device' or "? device' or even the "bossa program port" which supposedly it sometimes shows as.

Thanks for any ideas!

Be sure that the board is powered up using the 5 Volt external power-supply before you make the USB connection.
