I'm using OE (Generic.x86_64-3.95.2)

I've tried restarting tvheadend via SSH but to no avail. I also just tried plugging the stick in my powered USB hub in case there was some lack of power there. And have just flashed the latest BIOS firmware on the NUC. No difference with that either.

I've got an old ASUS USB TV stick which works fine (SD only, hence the new stick!)

Strange, I got the same OE version, an i3 NUC and the same PCTV 290e stick and it works out of the box. Can you run "journalctl --no-pager -b -0 | pastebinit" to get the syslog and send the link?

I did not notice any difference whether the stick was plugged in directly or in the hub.

lsusb for me shows:
Bus 002 Device 003: ID 2013:024f PCTV Systems nanoStick T2 290e

In case you want to compare the syslog, my output is here: http://sprunge.us/SXeQ
