I have run DMESG during the disconnect and there were no messages during
the time of disconnection. I ran: dmesg -w -T to follow the output.
However resetting the USB device worked, so at least now I can now save
a reboot:
$ echo 0 | sudo tee /sys/bus/usb/devices/1-4/authorized
0
$ echo 1 | sudo tee /sys/bus/usb/devices/1-4/authorized
1
I am yet to try a new port/cable (the host is offsite).

You really need to look at kernel-level messages.
