Did you unplug/replug the USB cable from the desktop? When first enabling
this with the cable plugged in, it seems to require a re-plug to get DHCP
to issue an IP. But I suppose your dhclient request from the desktop side
should have triggered this.

Do you see a tether interface (ip addr)? Attached log has output from ip
on bone. And of course, if you have rebooted, you need to enable the
tether again unless you have setup things for persistent tethering...some
connman config parameter.

Note also, that I have a wired connection on eth0 as well as a powered hub
with a TP-Link and BT dongle attached. Not that the TP-Link and BT dongle
matter. But I am wondering about eth0.

Pretty much same as mine.
FWIW, I also have /etc/connman/main.conf:
# Place this file in /etc/connman/main.conf

Didn't have to do that. Well, maybe that would have negated the need to
re-plug the cable. I have an IP on the host side:
