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=270305.0

Multi-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: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx so that my block erupters would work in bfgminer.

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.

First of all you need to choose if you will be using cgminer or bfgminer. You indicated you've installed both the Zadig tool (to install the WinUSB drivers) and the UART to USB drivers. This is not going to work. cgminer needs the WinUSB drivers and bfgminer needs the UART to USB drivers. If you have both sets of drivers installed neither mining software will work properly. So, decide cgminer or bfgminer and then remove the other drivers you have installed.

If that doesn't resolve things, please use the official thread (http://thread.multiminerapp.com) and post the full unhandled exception text you mentioned. It would also help if you are using the Debug build (https://github.com/nwoolls/MultiMiner/releases/download/v1.3.36/MultiMiner-Debug-1.3.36.zip) from the releases page.

Hopefully that helps & good luck!  ;D

Thanks! I got it working afterwords. Had some trouble doing it yesterday because multipool was unable to connect to the download server for bfgminer. But now it works. I downloaded it, restarted Multipool and all my Icarus devices showed up. Thanks a bunch!
