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.
You'd need to rebuild the kernel.
sorry to reheat an old thread,
No, Thank you for following up on it.
but did anything come out of this? Do we need to add a quirk?
Dell said they tried to reproduce this, and couldn’t. Maybe it’s mouse
dependent, there are different revisions, and the ID stays the same.
Therefore, I wouldn’t add any quirk, until somebody else hits this
problem too.
What would be nice though, is to add a module parameter allowing to
enable that quirk.
Kind regards,
Paul
