Hello

I bought a used 1d from ebay and i loved every minute of it. I then decided to buy an other one. Thats when the problems started.

The problem being that the pc receives only one signal from one and not from the other in random order even though both 1D's are powered on, on different channels and not on usb hubs.


So
my question is: what can i do to fix this?

Any thoughts or inputs are more than welcome

Thank you
