[all variants] How To: Mount USB (Flash, Jump or Thumb) drives in LiveCD

I'm in LiveCD just now. I have to thumb drives, one is 8 gig the other 32. I want to move the contents of the 8 to the 32. I used gParted to look at the sizes. There is 15 gig free on the 32 device and only 7 gig on the 8 gig.

I cannot mount these devices in LiveCD. I see no help via Google search. I wouldn't be asking, otherwise.
