Comment 85 for bug 1766076

I have a similar problem with a USB mouse, except in my case:
* Unplugging the mouse from the dock and replugging it fixes the problem.
* If I do nothing, the kernel appears to disconnect and reconnect the mouse with a new device number, and it works again until the next hang.

Dell Precision 5530
Ubuntu 18.04 with latest HWE kernel (5.0.0-32-generic)
Latest 5530 BIOS (1.13.0)
Latest TB16 Firmware

I have dual-boot linux/windows and all PC / dock drivers are up to date according to the Dell Command Update running in Windows 10.

dmesg from one disconnect / reconnect cycle - mouse froze around 60 seconds before this was logged
