After updating to the latest drivers and BIOS I've been having issues with the TB16 dock. It seems that while connected to the dock, my mouse works for about 5 seconds and then it just becomes dead. My keyboard is registering odd keystrokes and is almost unusable.
I've recently installed the latest drivers from the dell website using the "Auto Detect" feature. I have an XPS 13 9360.
I've been reading around about this issue and it seems that there are quite a few people that have this problem. Some of them have fixed it by downgrading the BIOS but I don't think that's a viable acceptable solution for a bunch of products that are supposed to be top of the line.
