ioctl HIDIOCGRAWINFO error using CM108 PTT
I've been using the DireWolf 1.5 Beta for the CM108 PTT feature (Thank you!), but it shows an error in the logs even though it seems to work and triggers my PTT just fine. The error message may be a false positive.
The exact error message is "ioctl HIDIOCGRAWINFO failed for /dev/hidraw0. errno = 0.", and it repeats multiple times during a session. I'm using RMS Express on Windows 10, and am connecting to DireWolf on my Raspberry Pi 3 over TCP KISS. I'm using the latest build of Raspbian Stretch Lite with all updates applied. The error only appears when I transmit. I've tried running DireWolf as "root", and as the "pi" user, but it makes no difference.
When I first used the CM108 adapter for PTT I simply used PTT CM108 in my config file as described in the user guide, but DireWolf gave this error in the logs:
Config file line 18: Could not determine USB Audio GPIO PTT device for audio output plughw:1,0.
You must explicitly mention a device name such as /dev/hidraw1.
So I changed the config line to PTT CM108 3 /dev/hidraw0 and now it works, but gives the error message.
Here's some typical log output:
