I think I had the same problem, had to disable the "Places status indicator" gnome-shell extension.

Hi;

I have Fedora 27 installed in a Lenovo ThinkPad P51, working pretty
good since november, but today, after the last update, Gnome crashes
when I connect any device in any usb port, usb stick, external drive or
mobile phone.

The last messages in dmesg when I disconnect the usb are like the
following:

[  281.527389] cdc_acm 1-1:1.2: urb 4 failed submission with -19
[  281.528593] xhci_hcd 0000:00:14.0: WARN Cannot submit Set TR Deq Ptr
[  281.528607] xhci_hcd 0000:00:14.0: A Set TR Deq Ptr command is
pending.
[  281.528610] cdc_acm 1-1:1.2: urb 13 failed submission with -19
[  281.529927] xhci_hcd 0000:00:14.0: WARN Set TR Deq Ptr cmd failed
due to incorrect slot or ep state.

In don't know where can I search to solve the problem.

Any help would be appreciated.

Cheers!
