Hi,
When I use xusb with my product I have this message:
Reading Extended Compat ID OS Feature Descriptor (wIndex = 0x0004):
00000000 28 00 00 00 00 01 04 00 01 00 00 00 00 00 00 00 (...............

00000020 00 00 00 00 00 00 00 00 ........
Reading Extended Properties OS Feature Descriptor (wIndex = 0x0005):
Failed: Pipe error
In the source code I see that:
- Extended Compat ID is read with LIBUSB_RECIPIENT_DEVICE
- Extended Properties OS is read with LIBUSB_RECIPIENT_INTERFACE
When I use LIBUSB_RECIPIENT_DEVICE for read Extended Properties OS it's ok.
So, I'd like to, understand why LIBUSB_RECIPIENT_INTERFACE is used.
Thanks,
