Arch Linux

I have Logitech Lift Vertical Ergonomic Mouse (the right-handed version). It's a wireless mouse. I use it with a USB dongle that comes with it. It worked perfectly fine until a recent systemd upgrade.

After upgrading packages systemd, systemd-libs, lib32-systemd and systemd-sysvcompat from 253-1 to 253.1-1 the left and right buttons suddenly switched places! Left button now acts like right button and right buttons acts like left.

I confirmed that with xev, it now reports left button as button 3 and right button as button 1.

Downgrading those packages back to 253-1 fixes the problem.

The problem only happens when using the USB dongle. If I switch the mouse to bluetooth mode, left and right buttons are back to normal.

Interesting thing is that the mouse starts acting like this immediately after upgrading, no reboot required. I suspect it happens at the hook "Reloading system bus configuration". But a reboot is still needed to get it back to normal after downgrading, which is strange.

Here's the device ID from lsusb:

Bus 002 Device 006: ID 046d:c548 Logitech, Inc. Logi Bolt Receiver

Let me know if there's any other info I can provide.
