HID filestream.write freeze

[blabla]

hi,
I had written a HID C# tool based on wimars  c# filestream implementation. But i still have problems with
some software freezes. The write  m_oFile.Write(oOutRep.Buffer, 0, oOutRep.BufferLength) funktion freezes - sometimes. Especially when you send and receive much data.
Is the a way to debug the write function? Or perhaps someone has the same problems and a solution?


Thanks
Alexander


PS: my tool is communicating with a ST µC with 64byte frames in 1ms update interval

A protocol analyzer will show what is happening on the bus and can help you find out if the device firmware is failing and if so, how. For example, is the device NAKing all incoming data?

If you don't have a protocol analyzer, use whatever debugging tools you have to find out what the host is sending and how the device is responding.
