1 year ago The nuget package was published by the original author, who is not affiliated with this fork. There are many known problems with the library’s parser (see other open tickets), a few of which have been remedied here. I’d honestly suggest trying out libusb/hidapi instead - as it’s a lot better maintained - and writing a C# wrapper on top.

1 year ago Oh ok, sorry I thought you were at the origin of the package. I don't have much time nor the knowledge yet for writing a libusb/hidapi c# wrapper, but thanks for the advice (there seems to be a few available out there). I've found how to avoid the bug for now, by keeping 8 bits in report sizes (which is not very satisfying of course, as I know a few devices that may not work). I'll probably consider your option later.
Hi, thanks for your work. I'm developing a usb device (gaming pedals), and I have a strange bug when adding vendor defined fields in the descriptor. When using the dll from the nuget package the lib is failing retrieving the descriptor, but when I compile the dll from the source I have no problem.
I'm not sure if it's the cause, but it happens only when the report size field of the last vendor ID declaration is 4 bits. When I set it to 8 bits it works. In all case the size is a multiple of 8 bits as report count is 4.
The descriptor is the following byte array : uint8_t descriptor[] ={0x05,0x01,0x09,0x4,0xA1,0x1,0x85,0x1,0x05,0x01,0x16,0x0,0x80,0x36,0x0,0x80,0x26,0xFF,0x7F,0x46,0xFF,0x7F,0x09,0x30,0x09,0x31,0x09,0x32,0x75,0x10,0x95,0x3,0x81,0x2,0x06,0,0xFF,0x75,0x10,0x09,0x10,0x95,0x1,0x81,0x2,0x06,0,0xFF,0x75,4,0x09,0x20,0x95,0x4,0x81,0x2,0xC0,0x05,0x01,0x09,0x3A,0xA1,0x1,0x85,0xFF,0x05,0x01,0x09,0x3B,0x15,0x0,0x26,0xFF,0x0,0x35,0x0,0x46,0xFF,0x0,0x75,0x8,0x95,63,0x81,0x2,0x06,0,0xFF,0x09,0x01,0x95,63,0x91,0x2,0xC0};
