P73 dock has usb errors until system reboot

2020-07-21, 2:17 AM

I have a P73 and thunderbolt 3 dock gen 2 (40AN). With somewhat annoying regularity, sometimes when I plug it in it does not work and requires a system reboot. It appears to be triggered by some combination of sleep/resume/suspend/hibernate/connecting egpu/disconnecting egpu although I haven't been able to isolate exactly what causes it, except that it happens pretty much daily (the dock is at my work, and more often than not when I come to work and plug it in, it happens)

 

 

Just wondering if anybody can shed some light on what is causing this, how I can fix it, how I can avoid it, or how I can recover from it without a full reboot. Attempts to disable/re-enable or reinstall drivers have not been successfull.

 

Windows 10 10.0.18363 Build 18363

P73 with RTX 3000

Occassionally plugged into a Razor CoreX eGPU with a Zotac 1070ti. Had to install 446.14 NVIDIA drivers from the website in order to get this to work properly (without it, every time the eGPU was disconnected, the RTX3000 would fail)

 

 

Thanks!

This might be related to what at least two of us are experiencing:

Just wanted to note that turning off the power management features as suggested in other thread didn't resolve this for me.
