Logitech mouse HID++ issues with the 6.7 kernel?

Since the 6.7 kernel my Logitech mouse often feels sluggish. Logs (e.g. dmesg) then shows multiple new connects:

[ 1021.743028] logitech-hidpp-device 0003:046D:406D.0004: HID++ 4.5 device connected.
[ 1031.093066] logitech-hidpp-device 0003:046D:406D.0004: HID++ 4.5 device connected.
[ 1031.495039] logitech-hidpp-device 0003:046D:406D.0004: HID++ 4.5 device connected.
[ 1034.778985] logitech-hidpp-device 0003:046D:406D.0004: HID++ 4.5 device connected.
[ 1053.971076] logitech-hidpp-device 0003:046D:406D.0004: HID++ 4.5 device connected.

Anybody else experiencing this issue?

Plugging the Logitech 2.4 GHz receiver dongle from the back to a front USB port seems to have fixed the issue. Maybe there was a sudden knot in the wireless cable? :person_shrugging:

it is now connected to a usb 2.0 port ?

usb 3.0 (xhci) has problems with usb devices like Bluetooth that disconnects often, plugging it in a usb 2.0 port fixes this This might be why you have problems?

This is an issue on kernel 6.7. Started happening for me as well after updating for 3 different Logitech devices (1x unifying receiver, 2x lightspeed receivers).

Frequent messages in dmesg about Logitech devices disconnecting / connecting when they are idle for a while.

The devices seemed to be working fine tho so it might just be increased log spam. Before updating to kernel 6.7 I only ever saw one message per device in dmesg when it connected and nothing else untill shutting down the PC.

Switched back to kernel 6.6.13 and the messages in dmesg are gone and won’t appear even if the device are idle for a long time.

I’m aware of that issue, so the dongle was placed on an USB 2 port for months.

First I thought it was a regression of the plasma 6 beta (which dropped on the 10th) and was waiting for that to shake out. But finally looking into it today the logs indicate the issue started at the 9th which coincides with the 6.7 kernel.

Something must have changed(?). It seems there are some HID++ changes in 6.7. Maybe those are the cause, but changing the dongle placement “fixed it for me”. :person_shrugging:

Like most folks, you may consider running the LTS kernel if you prefer stability over these issues.
