I currently mine scrypt with my GPU via Multiminer, and mine SHA-256 with my USB block erupters via bfgminer. I'd like to have them all in Multiminer but it doesn't detect my USB block erupters.
I installed Zadig as per instructions on this tutorial:
https://bitcointalk.org/index.php?topic=270305.0Multi-miner still wouldn't detect my devices, and now an unhandled exception error pops up every time I start Multi-miner. It still mines just fine with my GPU, I just have to see this error-message every time I start the program.
I reinstalled these drivers again:

I'd like to be able to do my bitmining in Multiminer because sometimes Zetacoin or PPcoin are slightly more profitable than Bitcoin and I'd like to be able to do automatic currency switching.
