Hi list, I'm not entirely sure if this topic belongs to this list, but as it might affect usbK integration, it seems the best place to ask first.
I've got a custom composite device with 3 interfaces for which I created a usbK driver package by means of the usbK wizard (interface 0x0). When using libusbx, the device works as expected if I'm just accessing interface 0, however as soon as I try to claim one of the other interfaces, I receive an error -12 from libusb_claim_interface. Here's some debug output: [ 0.332000] [00000c38] libusbx: debug [libusb_open] open 2.2 [ 0.333000] [00000c38] libusbx: debug [libusb_claim_interface] interface 0 [13.704000] [00000c38] libusbx: debug [winusbx_claim_interface] claimed interface 0 [17.954000] [00000c38] libusbx: debug [libusb_get_config_descriptor] index 0 [17.954000] [00000c38] libusbx: debug [parse_configuration] skipping descriptor 0xb [17.954000] [00000c38] libusbx: debug [parse_endpoint] skipping descriptor 30 [17.954000] [00000c38] libusbx: debug [parse_endpoint] skipping descriptor 30 [17.954000] [00000c38] libusbx: debug [parse_endpoint] skipping descriptor 30 [17.954000] [00000c38] libusbx: debug [parse_endpoint] skipping descriptor 30 [17.954000] [00000c38] libusbx: debug [windows_assign_endpoints] (re)assigned endpoint 01 to interface 0 [17.954000] [00000c38] libusbx: debug [windows_assign_endpoints] (re)assigned endpoint 81 to interface 0 [33.564000] [00000c38] libusbx: debug [libusb_claim_interface] interface 1 [34.414000] [00000c38] libusbx: debug [unsupported_claim_interface] unsupported API call for 'claim_interface' (unrecognized device driver) >From the ongoing topic (and recent fix) for composite HID devices, I'm extrapolating that a similar problem might be existing for handling usbK devices. Is it a misconception on my side, that it suffices to have a driver registered for interface 0x0 of the device? If I can supply more information, let me know.
