Stephan: >From kb832430: "Requests on the default control endpoint are limited to 4 KB for compatibility with earlier versions of drivers. The USB specification limits other control transfers to 64 KB. However, there is no specific limitation in the USB driver stack for non-control endpoints. The results of specifying a transfer that is larger than 64 KB on a non-control endpoint are undefined." http://aech.net/Driver/USB%E7%A8%8B%E5%BA%8F%E7%9A%84%E5%8A%A0%E8%BD%BD. doc=20 http://support.microsoft.com/kb/832430=20 http://support.microsoft.com/kb/200977/=20 You had select_configuration() commented out in pnp.c and if I uncommented it as it was previously coded with 65536 as the maximum transfer size, then none of my USB devices would function.

Can I assume that the HID backend is kind of working now? >=20 It's only working partially. The backend is fully coded but has not been tested very much and I don't know if real data transfers actually work. What's still missing are more unit-tests (see tests/src folder) and a test firmware that's 100% compliant with the HID spec (see tests/firmware folder). It would be really nice if someone with good HID expertise would contribute to this backend. > PICkit 2 does have two configurations, now it only display the first. Is this > normal? Yes that's normal. The descriptors you see when using Windows' HID driver are not read from the device (Windows doesn't provide any API for this). These descriptors are instead generated by the HID backend based on the information provided by Windows' HID API. Have a look at the source code and see how it works. The backend assumes that every HID device has only one configuration, one interface, and 1-2 interrupt endpoints. >=20 > And if I want to try out a libusb based program ported from Linux, how do I > use the HID backend (without using the device driver)?
