Hmmm... your controller may not be able to see more
than one device. There may be upgraded roms for it.
(I don't really know)
I had a RocTec HDD on my A500 and after a great amount
of testing I came to the conclusion it would only do
one device. With a HDD installed in case it would not
reconize the the external pass-thru port. If I removed
the HDD from the case then the external port worked.
You might have better luck with the GVP.
The rom is probably the problem and its possable GVP
did an up-grade for them.
