streamdeck-cli fails to find device in macOS 11.1

[spkane]

I am guessing that this is likely just due to the Linux focus with development and testing. I am happy to try and dig into this a bit as time allows but wanted to start by documenting it here:

$ brew install hidapi

$ streamdeck-cli brightness 50

panic: hidapi: failed to open device

goroutine 1 [running]:
main.main()
	/Users/spkane/dev/go/path/src/github.com/muesli/streamdeck/cmd/streamdeck-cli/main.go:36 +0x495

Some data for the record:

$ hidtest

I'm afraid I've never tried to run it on macOS myself, even though I guess it should theoretically be possible. Have you checked the file permissions of the HID device?

The device file on my system appears to be crw--w---- 1 spkane tty 16, 1 Jan 7 16:08 /dev/ttys001 which looks fine. That being said, I have no idea if the code is detecting the right device. Being able to turn on some debug output would probably make this easier to track down.

I faced same issue and resolved it by enabling CGO. This package depends on https://github.com/karalabe/hid and it requires CGO enabled on some scenarios.
