Been scratching around in here looking for a solution to why when I run the EVK1101 CDC USB demo I can't get my PC to see the correct driver and install it....
Yes, I've told my PC the driver is in :
C:\Atmel\AVR32 Software Framework\1.3.0-AT32UC3B\SERVICES\USB\CLASS\CDC\EXAMPLES\DRIVER, and the .inf file at32uc3xxx_cdc.inf is there, and I've even checked that the .sys files listed in the .inf file are present in my WINDOWS\system32\Drivers folder (this is an XP machine).... BUT, when it tries to load the driver, it tells me "The specified location does not contain information about your hardware".
So what's cooking here, should "just work" but it "just don't"  |

| Try going Device Manager -> Your CDC Device -> Properties -> Details -> Hardware IDS and check the VID/PID combination with the one given in the .inf file. If they do not match edit your .inf file accordingly |

Kind Sir, you are a genius!That is precisely the problem, and when changed, the .inf file correctly installs the drivers for the board and it shows up as a valid com port in my system.
Many thanks, you've saved me a lot of time! |

| I don't know about your OS etc. but if you are using Windows you should probably move to Studio 5.1 which comes with a way newer version of the ASF. The one you are using is really old and contains a lot of bugs. |
