Do not format the USB stick in box. It formats t to extX filesystem which causes hanging of the box on starting. Format it in computer, use FAT32 filesystem and try again.
You can also try to create two partitions on the USB stick - first small (FAT32) and second big extX or whichever fs you need.
I format my usb stick in the box, but i don't have any problem with stuck.
I don't think the problem is the way you format usb stick.
