Composite USB driver not working on Win7 x64

Question asked by Chris Lawton on Jun 2, 2015

I have ported the composite app demo in the USB stack tree (V4.1.1, KL25 target) to a custom KL46 board.  However, Win 7 is rejecting the .INF file provided ("doesn't contain a compatible software driver").  My PC runs Win7 x64.  I have modified the Mfr. string descriptor and the serial number descriptor in usb_descriptor.c, and modified the manufacturer string in the .inf file to match (.inf file attached).  Can you help me troubleshoot this issue?

 

Thanks,

Chris
