I guess the keypress insertion issue is still current , but simply
not relevant on the Pi (it does nothing in LXDE AFAIK).
It is still creepy IMHO but can be simply explained as code left
from demo purposes.

Thanks for the reply. If its fine on the pi I'll give the board modding a go - unfortunately the d+ connection has broken (track peeled off) and I can't find space to break back into the pcb before the track reaches the black dome (don't know the name - sorry!) So I'll pop back to poundland to get another.

Just spotted this thread... wow!

I also bought one of these poundland USB hubs last year (just to see if something so cheap actually worked!), and it looks identical to the other photos, but appears I got one with the 'regular' firmware, rather than the 'strange keyboard' firmware. It has VID/PID of 0a05:7211 (which is actually listed in http://www.linux-usb.org/usb.ids ) and lsusb -v reports

Maybe there's "good batches" and "bad batches" and I was just lucky to get one from the good batch?

It could be a keystroke logger. It could be a character injector. What you can see today might just be the tip of an iceberg.

It might be capable of all sorts of attacks. https://www.youtube.com/watch?v=1nhWV6kRdro

Not to do with USB hubs but here is another example of what is possible. https://www.youtube.com/watch?v=NuX_ElPhWHs

I bought one of these -6 Monte ago, no browser issue, but the cable broke. I'm looking at them three power slots longingly. But what is the Ec1 and Y1 for?
