This is weird, I haven't seen this issue before. Which USB host controller are you using, which OS and which version of libusb? -9 is LIBUSB_ERROR_PIPE, which means that the device probably sent a STALL, which again is very weird given that this issue never occured before for multiple users in the past. How often does this problem occur? Best Regards, Steve
