Re: LibUsbK Isochronous Write C# example

Hello,

Right, I was using the WinUSB driver. Replaced it and error 50 is solved
but now I get error 997 (Overlapped I/O operation is in progress) after the
write operation.
This is the DebugView log output:

I see something is out of range, so I tried reducing the number of packets
per transfer, but no luck. I think I need to solve the 997 error first. I
wonder what's causing it?

Kind regards,
Stephen
