Has anyone else noticed USB weirdness like this? Looking
at dmesg, that seems to be what the kernel thinks
happened:

Looks like a little less than 8 hours after the booted,
the kernel decided I just disconnected and reconnected
the mouse.
I have no idea what an EMI is, but that's what starts everything.
Hi Tom,
Probably not what you asked, but when does that stop me?
Is this a "add on" USB card? I have the worst luck with
add on USB cards in both Windows and Linux. My shop computer
has an add on USB 3.1 card that is a one shot card: I can read
a flash drive from it once. After I eject the flash drive,
I have to reboot to get it to work again. And this
was the forth card I tested. The first three just
corrupted the data or blew out.
Never have any issue with the USB ports on the motherboard.
Are the malfunction port(s) on your motherboard?
