Hi, I have just bought the Rio500 and tried to compile the Win32 DDK sample drivers (bulkusb.sys) to communicate with the Rio, but I am getting exceptions in the initialization routines. The guys who wrote the Linux support claimed that the riousb driver was very similar to this driver. I am obviously not getting it. Any hints? I can't even seem to see any debug output, I am using the dbmon and can see debug output from the shell, but maybe there is another trick. I'd also like to know how the message exchange between windows 98 and the Rio was monitored - is there a windows tool that lets you this? Did you use some hardware gadget?
