如何在 GadgetFS 中指定 HID 报告

Question

I am using GadgetFS to spoof a Nintendo Pro Controller through usb using these descriptors . However, I am not sure how to send the HID Report to the Switch. I know you can do it in ConfigFS, but I haven't been able to find endpoint support in ConfigFS, so I decided to use GadgetFS.

I have looked into varios resources like this and this . It seems like I should be able to send the HID Report descriptor through GadgetFS, but I can't find a way. It doesn't seem like USB_REQ_GET_REPORT is defined in any API.

My code can be foundhere which depends on the library found here . Finally, do I really need the HID Report descriptor anyway?

Answer 1

I think I have figured it out. When a device is an HID device, the bRequest value changes to some HID constants. Some of these HID specific constants can be found here .
