HURRAH! I have finally got it to compile...
I manually deleted the broken packages (I play too much anyway so a tidy up was in order) and it still failed with:
[1 of 1] Compiling Main ( usb1.hs, usb1.o )
usb1.hs:64:28: Couldn't match expected type `bytestring-0.9.2.1:Data.ByteString.Internal.ByteString' with actual type `ByteString'
Glad you got it to work! For future reference, the fact that the error message includes a package name and version number (bytestring-0.9.2.1:Data.ByteString.Internal.ByteString instead of just Data.ByteString.Internal.ByteString) is usually a very strong indication that the real problem is multiple versions of the package interfering with one another. -Brent
