No, I have not. I haven't tried yet - I will, though. Ideally, I would like to get the Windows build working through MinGW, so we could easily cross compile the Windows build from Linux. Okay, so I did some review and testing of your latest patch.

Not that I noticed a problem - I just noticed that there are a bunch more -Dxxyyzz arguments on compilation commands (vice having all the defines written to config.h). Just curious, mainly. > +int HID_WriteReport(const uint8_t *data) > +{ > + int err = hid_write(h_dev, data, USB_PACKET_LENGTH); > + if (err < 0) { > + debug("Failed to write to device: %d (%s)", err, hid_error(h_dev)); > + return err; > + } > + > + return 0; > +} I found a pretty substantial bug here. It turns out that hid_write requires that you pass it a 'Report ID' as the first byte - so we actually need to pass in a buffer of USB_PACKET_LENGTH + 1, and set the first byte to zero. So, here we'll probably have to copy the input data into a larger buffer, and pass that on. Because of the way hid_write() works, this bug is only seen when we send a packet that starts with 0x00. (See the hidapi.h header file for more info on the 'Report ID' requirement.) > + debug("Failed to write to device: %d (%s)", err, hid_error(h_dev)); > + debug("Failed to read from device: %d (%s)", err, hid_error(h_dev)); I think both of these should actually use %ls instead of %s because hid_error returns a wchar_t*.
