What do you mean with "properly describing an Isoc endpoint" ? Did the Windows driver reprogram the device to provide an isoc instead of a bulk video endpoint ? Or did the device have no video endpoint and the bulk endpoint was used for something different (likely device programming) ? Any chance to get lsusb outputs ?
If you don't have a device in the other state and didn't test the bulk endpoint's, how did you notice this issue ?
