libusb
Add hidraw backend for FreeBSD
FreeBSD support hidraw in Kernel from 13.0. By using libusb only, we can only see the HID device from usb. To address this, we implement hidraw backend for FreeBSD.
Just like Linux use libudev to handle usb specified HID stuff (like Manufacture), we use libusb to handle it.

Currently, some stuff like the Report Descriptor parser and error registry routine are copied from Linux and I think they are platform independent. Can we create a common directory or hidraw directory in code then put them inside?
Have tested by the hidtest program.
Thanks for @Youw your review:).
Then, What is your opinion about this?

I thinjk that is a good idea, but I don't think it really is nesessary to do so in scope of this PR. There are really lots of stuff which I'd like to share among beckends, and I think it is going to be some refactoring after all.
Nice. This will address the following issue.
- https://github.com/libusb/hidapi/issues/543
Oops. I forget we have udev-devd stuff. Maybe we should use udev also?
I lost context here. What for? Seem like you have all the functionality implemented already. Aren't you?

Yes, all functionality is fully implemented. I am just thinking if we should use libudev make hidapi more portable.
First test under FreeBSD 14.1 Release, under a physical machine (Chuwi mini PC, Intel J4125 CPU, 8GB RAM, 256GB SSD)
There are a few compiler warnings.

Fix it:). Forget to fix the warning.
Thanks. The compiler warnings are gone.
The Segfault issue is still there though.
Can you show me where it cause segment fault? You can use something like lldb with (sudo lldb <binary_location>). Then use r to run.
This is with Cmake build. Somehow it only build one version of hidtest.

Compile-time version matches runtime version of hidapi.
unable to open device
I found the reason. There are two usb hid driver in FreeBSD. One is uhid, another is usbhid. Only usbhid is compatible with hidraw. Also, unload and try to load usbhid is useless. The effective way to enable usbhid is through
sudo sysctl hw.usb.usbhid.enable=1
Then when next time it is auto-loaded, the usbhid will replace the uhid:
sudo kldunload uhid.
If uhid is not auto reload:
sudo kldload uhid
Oops. I forget we have udev-devd stuff. Maybe we should use udev also?
I lost context here. What for? Seem like you have all the functionality implemented already. Aren't you?
Yes, all functionality is fully implemented. I am just thinking if we should use libudev make hidapi more portable.
If udev is generally available on FreeBSD and can be used in a similar way as in Linux/hidraw - it is probably a good idea to do so. And probably linux shouldn't be used in that case at all. But I imagine that is a large change to this PR, so it is up to you.

Thanks. This method works to get hidraw to bound to the device.

unable to open device
@aokblast
Looks like it is getting close. To reproduce the above issue, you can probably change hidtest example to open one of your HID device instead of 04d8:003f.
Using hidapitester and the FX2HID example to test.
Unfortunately the new hidraw backend does not work. The old libusb backend has the issue mentioned in #274.
