Mouse Unusable (e.g., Logitech MX Master 3)，When using a combined keyboard and mouse receiver。

[zoushiyin]

When using a combined keyboard and mouse receiver, the mouse (e.g., Logitech MX Master 3) is not functioning properly. Specifically, the mouse does not work at all. We would like to know if this issue is specific to the Logitech MX Master 3 or if other Logitech mice also experience similar problems.

Did you try version 1.2 and/or pre-1.3?

[zoushiyin]

Yes, I tried version pre-1.3. The issue still persists with this version.

Thank you for your help!

Which color does the logo on the USB receiver have?

[yarodin]

I have MX Master 3S mouse and MX Mechanical Mini keyboard plugged through combined receiver (bolt, light green logo) without any issues on version pre-1.3

[zoushiyin]

The receiver is black, and the logo on it is "logi" in lowercase letters, not the "G" logo.

I tested with the latest version today, and the issue still persists. The mouse is not recognized at all; the cursor doesn't even move.

However, the Logitech receiver with the "G" logo works fine.

Thank you for your help!

Can you hook up a serial debug cable to GPIO0 and post the output?

[No0ne]

Ah I've got a mouse now so I can reproduce this, I'll get back to you!

[zoushiyin]

Thank you very much! I am waiting for your response online.

It seems it depends on whether the receiver is connected to a hub or directly to the pico 🤔

[zoushiyin]

I usually connect it to a hub, but it doesn't work even when I connect it directly during testing. Also, we need to use a hub to connect both the keyboard and the mouse.

Is there any good solution or workaround for this issue?

[No0ne]

I think I know where the issue is, its in the mouse report initialization, I'll get back to you!

Should be fixed in the latest pre-release: https://github.com/No0ne/ps2x2pico/releases/tag/pre-1.3
