libusb_interrupt_transfer return LIBUSB_ERROR_IO

[wangdaao]

I use interrupt transfer (libusb_ interrupt_ Transfer), return - 1. I'm pretty sure that the interface and endpoint I filled in are obtained from the descriptor, no problem. libusb_ open、libusb_ claim_ Interface is successful, only libusb_ interrupt_ Transfer always returns - 1,. Also try to give administrator permission to run, or failed. I'm using version 1.0.24.
