Subject: USB devices on Dell TB16 dock stop working after resuming

Dear Linux folks,

On the Dell XPS 13 9380 with Debian Sid/unstable with Linux 5.3.7
suspending the system, and resuming with Dell’s Thunderbolt TB16
dock connected, the USB input devices, keyboard and mouse,
connected to the TB16 stop working. They work for a few seconds
(mouse cursor can be moved), but then stop working. The laptop
keyboard and touchpad still works fine. All firmware is up-to-date
according to `fwupdmgr`.

Please find the Linux messages attached.

Kind regards,

Paul
