I have such a thing - a disk drive enclosure that can be connected to a PC and used as an external drive, or by flicking a switch it can be connected 
to a digital camera to download photos onto the drive, so it's acting in both USB roles.  It has a Female A USB socket, and comes with a male A to 
male A cable to connect to a PC, you use the camera's normal cable for connecting that.

I've just taken it apart, and the chips I can see are:

Labelled "Ali",  M5624H  A1,  0519  TH07,  XHGSH100000E

Labelled "SST",  39FV010,  70-4C-WH,  0502053-G

Labelled "Hitek", EP2084-010

There's a 12MHz crystal and what looks like a voltage regulator, the rest is just passives.

Hope this helps someone!
