Looks like a hardware issue, the kernel can not cause a device to
disconnect itself.
Especially as this happens with two different mice, you might want to
see if there's something wrong with that port.
With three devices of the Logitech model 046d:c077 (Logitech, Inc. M105
Optical Mouse) the problem could be reproduced on each USB port.
Have you tried enabling the always-poll HID-quirk, which is needed for
certain devices to prevent issues like this?
See commit bfe3c873e978 ("HID: usbhid: enable always-poll quirk for Elan
Touchscreen") for an example.
No, I have not. Is this run-time configurable, or do I need to build the
Linux kernel myself.
Also, I am unable to reproduce this problem with the *same* mice on a
laptop with a USB3 – it’s blue – port.
