Hi there,
I've got a little test program that I'm running against a device I have,
which is supported by the winusb driver. Here's my little test program:
int main(int argc, char* argv[]) {
libusb_context* ctx;
libusb_device_handle* dev_handle;
libusb_init(&ctx);
libusb_set_debug(ctx, 4);
dev_handle = libusb_open_device_with_vid_pid(ctx, 0x1050, 0x0211);
printf("dev_handle %p\n", dev_handle);
if (dev_handle) libusb_close(dev_handle);
libusb_exit(ctx);
return 0;
}
The program produces the following output when my device is inserted into a
USB 3.0 port:

Naturally it succeeds when the device is inserted in a USB 2.0 port. I've
verified the problem on an HP z420 with a TI USB 3.0 controller/drivers,
and on a ThinkPad T430 with Intel-provided controller/drivers.
Any idea what gives? Thanks,
