First, i've read a lot of bad things about these docks, but I do not having purchasing power in the company, so i have to use what I have.
That being said, I have a TB16 dock and a Latitude 7490 for a director that is causing a lot of issues with USB. Any keyboard plugged into the dock has a lot of latency. It can take anywhere from 3-5 seconds for a single letter or key press to register. In some cases, it may repeat a letter multiple times though it was pressed once. If you plug the keyboard into the laptop directly, there is no issue.
All the drivers have been updated, BIOS updated. I just got a replacement dock from our vendor, tested with the original and another replacement. All 3 have had the same issues.
I have turned off power management in the device manager for all USB hubs. I have disabled the Thunderbolt only in the BIOS.
Personally, I have some issue with the USB keyboard first thing in the morning. Since we take our machines home, when i connect the dock in the morning, it can take upwards of 5 minutes for it to register correctly before I can use it. In some cases, I need to power cycle the dock by pulling the cable and holding the power button for 15 seconds.
Anyone else have issues like these or similar that was able to resolve them?
