What version of Ubuntu do you have?

Do you get any indicator from your devices that you are at least getting an electrical current such as a usb status indicator. Particularly the camera?

Linux sees the flash drive, Ipod and Camera all the same; it sees them as filesystem devices similar to a USB Flash drive due to the driver installed within the kernel. You would in this case have to mount each filesystem manually.

Chances are you do not have your fstab set up to check for hotplugs. There should be an entry in your fstab similar to this:

#<fs> <mountpoint> <type> <opts> <dump/pass>
/dev/olympus /media/camera vfat noauto,user,exec 0 0

***Pay close attention to the options and the dump/pass section!***

Also if you have the means and knowhow, please check the voltage of your usb ports. They should be more or less 5v. This should be done to rule out hardware problems.

Good Luck.

Are the drivers installed? They have something like uhci and ehci in their names -- search this site for more information about them.
