RE: Dell TB16 - Latitude 7370 various issues
I am having the same issue, TB16 with an XPS 13 9350. The dock randomly disconnects for a few seconds, then reconnects (and I get some notifications about "new thunderbolt topology", etc.). The time between disconnects is very random, sometimes 30 minutes between occurrences, sometimes 2 minutes.
I also ran into the same problem with the ASMedia USB host controller driver, so I uninstalled it and have been using the generic Microsoft driver.
The only work-around that seems to work for me is leaving the lid open on the laptop - I have not seen the disconnects happening in this configuration. Still looking for an answer!
