Take note that libusbx does not isochronous transfer even though libusb0.sys has limited isoc support and libusbk.sys has better isoc support. Which version of libusbx are you using? You may need to use latest git version and use libusbk.sys driver only since libusbx has some problems with libusb0.sys as of now with regard to the filter driver and USB composite device. And take note WinUSB does not support isoc transfer. Please post the output of xusb.exe. I am not so sure if your device is a USB composite device with two interfaces (in that case, this device violate USB spec since the 2nd interface has a isoc interface) or a device with single interface but with an alternative interace (then it is okay). > In my host PC application when I try > to set active interface 1 I got error (from UC3A debug printout > message is USB_REQ_TYPE_STANDARD).
