Can I use both usb ports?
Hi can I read from one usb port while writing to the other (mini) one whilst simultaneously drawing power form it?
Are we talking about the Omega2? I see in the pinout that there is only one USB port. It is technically possible to use the two connectors to the same port as both functions are on distinct circuit/wires. However, a protection circuit would be needed to protect and isolate the hardware hooked up to the Omega2.
My recommendation is KEEP IT SIMPLE and only use one of the USB connectors for both functions.
