Yeah but it is not USB to HDMI
I suggest it is a Mini HDMI Male to HDMI Female you want.
Now I did not want a special full length cable, instead I wanted an adapter that I could use with a regular Male-to-Male HDMI cable.
It's best also to get one on a short lead so as not to stress the socket on your tablet.
I am in the UK & got the adapter for only $3 inc postage & no customs.http://www.ebay.co.uk/itm/150797827177
If bad link search ebay.co.uk for item 150797827177
or search for MINI HDMI /M to HDMI /F Cable for Archos 101
It came from China but arrived in 12 days, they ship worldwide.
The adapter works well & the display is great on an HDMI TV.
But one really annoying thing is that the Tablet Screen switches off when you select TV out.
I would much prefer it remained on, as you need to use the touch-screen for control.
If anyone has a solution to that I would like to hear.
Good Luck & I hope this helps
