Dell firmware update utility shows a warning message. Too many Dell Docks are attached. This update utility only works when a single Dell Dock is attached. Only connect a single Dell Dock and restart the update utility, when updating the firmware on a WD19TB docking station when connected to a thunderbolt monitor. For example, a UP2720Q or UP3221Q monitor connected to WD19TB causes the warning.

Cause
Monitor and Salomon USB Hub have the same VID/PID, so Dell Firmware Update Utility (DFU) recognized two docks to show the warning message.
Resolution
Disconnecting the thunderbolt monitors before updating the firmware.
