Have you done the WakeUp call (SYS

Where is this documented?

It isn't =:-O

Not apparently in the paper PRMs; there is
of course an entry for DeviceFS_CallDevice, but it doesn't elaborate on
any reason codes. The StrongHelp manual shows DeviceFS_CallDevice 3 as
requiring devicefs_stream% in R2, rather than devicefs_stream%!28.

See the csa.programmer thread called 'Castle USB stack programming'
around October 2004, it's mentioned in a posting by Dan Ellis.

I'm using DeviceFS_CallDevice,&80000003 to set the initial
devicefs_stream% variable rather than the method in the thread, this is
documented in the Castle USB API notes.

I don't think I've tried quite everything yet; but I've solved my
immediate problem by going over to the Simtec stack on the Risc
PC, which seems to do non-blocking inputs very well.

Thanks to everybody for your help. I will get back to this
another day. Meanwhile I have a USB device to write :-)
