Describe the bug
Adapter CU0019 not recognised (same on windows Logitech utilities). Tried multiple of these adapters.

To Reproduce

1. Plug in
2. Start solaar

Update just seen the docs..
Some Nano receivers are only partly supported as they do not fully implement the full HID++ 1.0 protocol. Some Nano receivers are not supported at all as they do not implement the HID++ protocol. Receivers with USB ID 046d:c542 fall into this category.

[pfps]

It might be the case that Solaar can do a better job of supporting the C542. Solaar 1.1.7 has code to recognize more receivers, and the comment about the C542 may be in error.

Upgrade to version 1.1.7 if you have not already done so.

Run Solaar with the -ddd option and post the resulting output. Also try the instructions for adding a new device in the device documentation.

[yesimxev]

Tried 1.1.5, I'll upgrade next week as it's at work and let you know.

Hmm. Can you try the process for adding new devices from https://pwr-solaar.github.io/Solaar/devices? Use this issue instead of a new enhancement issue.

Your information confirms that this receiver does not have the ability to either send or receive HID++ messages. Solaar is only for devices that use HID++ so Solaar does not support this device.

I have no idea why Logitech is using a different protocol for this receiver.

[yesimxev]

Thanks for your time though 😄

For future comparison here is the output from a Logitech Unifying Receiver, which does use HID++

The relevant parts are the vendor-defined usages with report id 16 and 17, which are for short and long HID++ messages, respectively. A device that supports HID++ will have one or the other of these.
