Hello, 1st post.
Xmas Day, 10yo daughter’s dream present, think I’ve blown the hub.
Having issues with the Pi-Top recognising the Pi-TopSpeaker, will write another thread after this one.
I foolishly tried to unplug the speaker and put it back in again while running, in an attempt to see if it was recognised. Accidentally inserted the wrong rail and everything went dark real quick.
The RPi is still working (plugged it into a spare mk1 CEED we have), there’s power from the wallwart (tested with multimeter) so guess it must be the Hub (no lights when attached to power).
Anyone any ideas or wisdom?
This has gone down about as well as you’d expect 
Cheers,
Julian
