Ahhh, sorry - missed that part of the readme. I've fixed that now and running "/usr/local/bin/gphoto2" from the command line works fine. Not sure if I was confused into thinking "gphoto2" would work by itself, but its not a big issue anyway.

Wow, it runs superbly! These commands all function fine: http://www.gphoto.org/doc/manual/using-gphoto2.html I'm currently dumping 1.5GB of photos from my Canon A610 to the n810's memory card (USB Host connection). Just what I needed, cheers for your help! Would be happy to do any further testing if need be.

EDIT: File dump completed perfectly, now to upload to flickr with altpublisher (http://www.youtube.com/watch?v=hhgwP8HcNUo ). I tried out --capture-image afterwards, which reset the tablet...
