This is a quick fix for isochronous (ISO) endpoints that does not require changes on the
usb-device.There is already PR #29 for ISO endpoints pending, which seems to aim at a more sophisticated solution. I propose to integrate the present PR as an intermediate solution.
Successfully tested on STM32F446 on FS using a Linux host with different values for endpoint
bInterval. Got reports on successful experiments on HS.Primary use case: audio streaming according to USB Audio Device Class, Release 1.0
