Digital editions does not recognise Samsung Galaxy Tab 7.7

Question

Digital editions does not recognise my Samsung Galaxy Tab 7.7. The device is authorised. Please help. Thanks

Answer 1

Your last post is confusing - and the technology is unforgiving.  So let me
see if I can piece this together....
Starting with the Tab 7.7: some manufacturers have devices that they
improve upon and claim compatibility because they're 'just like' XUY that
they made last year.  Sometimes this is true, but often, the user ends up
with claims and not much function.  Samsung is pretty good about this, but
you can't assume that, just because you can connect the Tab to your
computer and move stuff back and forth, that the programs on your computer
are going to work with your Tab - and vice versa.
The OS on the tablet is NOT compatible with ADE, so you can't drag and drop
ebooks as you would with other ereaders.  You have to use utility programs
to move the ebook to your Tab.  Once you move the ebook to the tablet,
Aldiko should be the program that you use to read the ebook.  In your
situation, all ADE is doing is retrieving the ebook from the source, and
storing it on your computer.
You mention "software/apps that are available for DRM".  DRM is the copy
protection on an ebook.  It's a software switch built into the ebook's ID
file and all that it does is to tell you whether or not you can copy or
print the ebook.  ADE and Aldiko look at the switch when you open or try to
copy the ebook.  And if the DRM settings are preventing Aldiko from opening
the ebook, you're stuck.  Those settings come from the publisher,
distributor or author, not from either ADE or Aldiko.  You can try to open
the ebook on your computer with ADE and see if you get the same results.
You mention error messages.  I think, from the context, you're getting them
on the Tab when you try to do something with the ebook.  Any messages
relating to time relate to the settings for your time, date and time zone.
I'm guessing here, but I think your Tab's settings aren't the same as your
computer's, and that's why you get the 'expired' message.  The 'unknown
error' message may be from Aldiko - and we're not equipped here in the ADE
forum to deal with that one - sorry!  If the error message section of the
Aldiko user guide doesn't tell you either, then you might be able to find
out what to do about it from an Aldiko forum.
Your Overdrive comment has me puzzled.  I looked for some context in the
other posts in this stream, and I didn't see anything that helped.
Overdrive is a 'elibrary management system' that does much the same thing
as ADE does.  So, you can import and export ebooks via Overdrive.  Your
situation seems to revolve around how you get ebooks onto your Tab and then
get Aldiko to open them for you to read, and I don't know if Overdrive
supports the Tab either.
