Now:
Code: [Select]
packet-size=0 length=64
I think manual entering  packet-size=64 may solve problem.

Hello

Thank you for your information.

Unfortunately we still can not find correct usb device with isochronous pipe for full test on our side.
We tried various USB audio speakers, microphones, web-cameras and BT adapters. They do not provide iso pipes.
Therefore I'm asking you about new details again:

0) What usb device do you use? (name, model, url)
1) What version of windows do you use?
2)  Do you get same troubles on other PC?
3) Do you get same problems with x64 platform?

We see some strange messages in the log. They report about error but it is not nrComm Lib code.

USB microphones and cameras provides  isoch pipe. But this isoch pipes hidden.  When you start voice or video recorder application which uses this devices, isoch. pipe present and active and send streaming data.

  • My device is custom device. Generated  via Microchip device demos. 
    Firmware build myself.  Properties as descriptor attached. My device doesnt need any recorder application for sending isoch pipe 
  • Windows Vista Home Premium 32 bit used for test.  Device and nrusb not tested on other pc and 64 bit platform
