if the motors are in series rewire them to be in parallel series --A--B-- parallel |--A--| |--B--| make sure they dont overload the usb - you can blow a fuse inside the computer which is quite hard to replace if they allready are in parallel there is no much to do without more complex electronics. find another power source

if you want to power it by usb cable, just add in another one (not an expert in electricity, so dont trust me...research) or just use a higher voltage supply...
