Hi,

 Iam having problem with syncSubmit(buffer) function. If the buffer size
specified is very large (on the order of 17000-19000 bytes), then this
function is failing. UsbException is invoked with the following error -
Error submitting IRP : Invalid.
But if the buffer size is around 16000 bytes, it works fine.

 Any suggestions as to why this might fail and any solution to this problem?

Thanks
Sathya
