F the 2nd time in 2 days my mouse stops responding on my linux workstation.
I cant control the location on the screen to pop up so I cannot even use my keyboard to try to recover.
Yesterday when it happened I finally restarted my machine via   ps ssh, and when it restarted the mouse
responded normally.
now, it has happened again!  I need some help diagnosing this.
I have reseated the usb connection, swapped ports, changed mice, no response.  I dont know if the linux machines are hot swappable for usb ports or not.

I cannot continue rebooting my machine when this happens!
Is there some port diagnostic I can run

I don't understand what you're saying there.

When the mouse stops working, do Ctrl+Alt+F2
Login to tty2 with your username and password

Unplug your mouse and run
$ dmesg -r | tail

plug the mouse back in, up arrow and hit enter to again run
$ dmesg -r | tail

Is it detecting your mouse?

You should be able to return to the GUI by using either
Ctrl+Alt+F7 or
Ctrl+Alt+F1


You didn't mention if the mouse is cordless, but if it is, recharge/replace its battery/batteries.
