USB flash drives don't show up

[JQ245]

I've been running an eMac that is nearly 10 years old, and, while its still kicking, I needed to upgrade finally. So got a used macmini (mid 2010), because I can't let go of the CD/DVD world yet. It's like new, running Lion, and is connected to a 24" RCA LED LCD HDTV. My problem is that in trying to carry over files from my old emac to the mini, when I plug in a flash drive (anywhere—Gigaware 4 port, back of the mini, keyboard) it will not show up on the desktop. I will be able to see it in DiskUtility, but even after reformatting, it won't show up. What can I do? I realize I have other options to swap files, but still would like to have my flash drives work.

 

Thanks for any advice,

Jon

Can you access it in terminal?

 

In finder do you have show on desktop checked in preferences and did you select mount device?

 

I know that the keyboard slot doesn't have enough power for USB drives. They will show in disk utility, but, not in finder. The other slots should work unless you have a bad USB hub in the mini.
