As some of you know, I've inherited an unusual development environment in which IAR is used for development/build and Atmel Studio for debugging. I'd like to use one or the other entirely, for lots of reasons that I won't go into here. In trying to debug with IAR, I'm getting an error: Failed to initialize USB driver: error 0x20000007 ("Internal System Error").
I know that USB drivers have been a sore subject for AVR developers in the past. Is there currently a favored source for a driver that will work with IAR?
Windows 10 (yeah, I know)
IAR EWAVR 6.12.1
Atmel/AVR JTAGICE MkII
I could probably obtain a different ICE device if that's recommended.
Thanks for any help.
