Have you tried to do an firmware update?
If not, please try it.
Format your USB stick with FAT32 and then create the following folder structure and exact folder names:
Rigs is inside of Shared!
Copy the kaos.bin to the folder "OS Update".
That should do the trick.

Tried it with 2 different cards - the same "ERROR: unable to mount USB device "
Maybe it shoud have some hidden files?
That's strange indeed. No hidden files, no system files. I have no clue what makes it a KPA stick, sorry.
Doesn't work out of the box 
Will wait for support answer...
What you can also try:
Reformat the USB stick again.
Put the KAOS.BIN in Root Directory of your USB stick, plug it in and start the KPA with <PAGE> pressed.
This way you boot directly from USB.

I've tried this already and it didn't help.
Did you try the full system reset?
Note: ALL the rigs will be erased during this procedure!! ( credit to billruppert)
Maybe this will help and since you didnt create any rigs, you will loose nothing.
