Question about PB 626 usb connection

When I attach the USB cable to the PC and select PC Connection all that happens is I get a Pocketbook626 under 'devices and printers'. It lists the function of 'Nook Android Interface' under its properties. Which rings no bell at all here. I can disconnect the 'Pocketbook626', but what I do not get is a drive with the files on my PB626. Which I expected and desparately want.

Can anyone help me out (google doesn't).

Thanks.
