The mouse stops to work until physically reconnect.

I found this: https://www.raspberrypi.org/forums/viewtopic.php?p=864077
which is similar to my problem
$ apt list --installed | grep mtp

libnet-smtp-ssl-perl/xenial,xenial,now 1.03-1 all [installed]
It seems MTP is devil here:
https://sourceforge.net/p/libmtp/bugs/435/
How this is resolved:
https://bbs.archlinux.org/viewtopic.php?pid=1015265#p1015265
But commenting out that will ignore MTP devices.
I found [this](https://askubuntu.com/a/506504/405408) which suggests to
put my device into `69-libmtp.rules`
Please exclude my device from MTP probe

Title:
specific USB devices disconnect and don't reconnect
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Yakkety:
Fix Released
Bug description:
2 USB ports randomly disconnect and don't reconnect (it's always the
same two), and in dmesg all I get is
"
[ 1276.916458] ohci-pci 0000:00:12.0: HcDoneHead not written back; disabled
[ 1276.916467] ohci-pci 0000:00:12.0: HC died; cleaning up
[ 1276.916553] usb 3-1: USB disconnect, device number 2
[ 1277.017302] usb 3-2: USB disconnect, device number 3
"
This only started happening when Yakkety went to the 4.8 branch, with 4.7
branch this doesn't occur, hence the bug report since it's unlikely that a
hardware failure will only stick to one OS and one branch of the kernel for
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested
that in the past couple of days)
