It would be nice if I could get it to work.

Note that I don't say that it doesn't work, it's just that I can't persuade it to. It is supposed to connect my Samsung pad to card readers, memory sticks etc. As both pad and gizmo are new to each other and to me, how do I decide which of the three is duff?
And yes, this is a bit of an emergency blip, I'll try harder tomorrow.
