Sorry – no. There are two types of USB devices, a host (master) (like a computer) or a peripheral (slave) which connects to a computer. The pedals are slave devices.
Slave devices cannot talk to each other. A master device can only talk to slaves, not another master.
Theoretically, you could create a computer application that would read from one slave and send the result to another, but I have not heard of such a thing, and, you would still need the computer. So, not very useful.
