You can find USB thumb drives, the odd USB HD and a few other things. They
stopped selling cards, RAM, etc. claiming they are not profitable.

I got my Hub at Goodwill (it was gonna be tossed in the trash as they don't

Only two of my Hubs are full.
1 has another hub plugged into it (with 1 USB thumb drive, this is the
POWERED Hub that has 2 bad sockets. And no, the power supply won't work in
the Belkin)
1 hub has a Digital Camera that is plugged in thus it doesn't take power
from the hub. The other digital camera has 3 AAA batteries (I checked and
they are practically new. I was told they will be drawn on for power unless
I remove them)
