Hello Jan.
Thanks for your book and work.
At the latest winusb_cs_31 there is the isochronous transfer test, but in the firmware source code (device-winusb_lvr.zip) I did not found any isochronous endpoints in the device descriptors and any code for isochronous transfers. What shuld I use for test isochronous transfer via WinUSB?

The above example uses 3 endpoints for bulk transfers and unfortunately none isochronous. Is there an example of a configuration descriptor for WinUSB device uses isochronous endpoints for your .net app (winusb_cs_31)?
