Is your feature request related to a problem? Please describe. Device not recognised by Solaar.

Describe the solution you'd like Ideally device to be recognised and (at least) battery status reported by Solaar.

Describe alternatives you've considered Guessing when the battery will run out, with poor accuracy.

Additional context No context required, request to support a currently unsupported device.

Please provide the information requested in https://pwr-solaar.github.io/Solaar/devices

EDIT: I see that you did, but it was in a detail section. It looks as if the device does use HID++ and should be supported by Solaar.

Please provide output of solaar -ddd with the device active to see what is going on when Solaar is trying to connect to the device. I suspect that hid_parser is not installed. See the Known Issues for more information.

You are quite right, hid-parser wasn't installed and adding it fixed the detection.

The section came from the template for creating a request - I thought that was where you would expect the files to be (in "Details").

Sorry for the noise, I only discovered Solaar existed today. Awesome tool, thanks for creating and maintaining it!

[pfps]

Please provide output of solaar show. That information will be used to help solve problems encountered with the trackpad.

Hi,

Here's the relevant part of solaar show:

$ ~/.local/bin/solaar show

Thanks. I see that there are not very many features, but that battery information is being reported.

[loz-hurst]

Indeed, it doesn't do much (it's just a touchpad surface - no buttons or anything other than power and the connect one on the bottom). I'm mainly using Solaar for battery monitoring :)
