Hello, I am also interested in SCSI, PCI, etc. I think the main problem/issue vis-a-vis USB/SCSI/PCI et. al. for Haskell is does (or will there exist) a Posix API and a Windows API for these buses/protocols? I read one URL but it will only support Linux. Ok .. maybe there API will be implemented for other Posix OS's like solaris, AIX, HP-UX, etc. but I wouldn't "bet the farm on it". I am not trying to be pesimistic but just save Marco some time in his life. Maybe Marco should talk to the people doing the Linux implementation for the "Posix" API and see how viable that API is before spending a year for nothing. Or Marco maybe you can be a trailblazer and come up with a better "Posix/Win32 USB API" and implement in Haskell? ;^) Very kind regards, Vasili
