New project has me digging up a 2 year old SAM4S Xplained eval.  The issue is - I cannot get the USB driver to successfully install for this eval board.

I have logged a tech support issue with Segger, and find they are 0 help with this.

Anyone out there in Atmel ARM based land have any suggestions?  (aside from reinstalling windows 7...)

FWIW the SAM4S Xplained Pro driver works flawlessly on this PC along with Atmel Studio 7.

Thanks,

Mark

SOLVED!

After much struggling, I had a coworker plug the SAM4SXPLAINED board (the board) into the usb port on his Intel based PC. This PC had no Atmel Studio or xplained board drivers previously installed.  A driver was automatically searched for and found and the board was recognized.  

 

At this point the PC noted that firmware needed to be installed and downloaded firmware to the board.  I was not sitting in front of the PC, so not sure what the display indicated.  

 

We unplugged the board from the Intel PC and reconnected it to the usb port on my AMD64 based PC.  The board was recognized as a JLINK CDC UART Port(COM8) in Device Manager.  The Device Manager, however, indicated an "unknown device" under Universal Serial Bus Controllers.  At this point, it seemed the board and driver were only half working.  I gave up and turned of my PC for the weekend.

 

This week, as a final attempt, I went into Device Manager under Universal Serial Bus Controllers and clicked on the unknown device.  The details indicated it had no driver installed.  Just for fun, I clicked to install a driver and pointed it to the directory containing my latest Segger driver download.  Eureka!  It installed and the board can now be programmed and debugged using Atmel Studio 7.
