Thanks for this link. But I hope that the Neo1973 hardwareteam

is plugged on a PC?

In case that the Neo1973 wound have a powerd USB port,
it would be interesting to hack it (maybe together with
a FPGA to switch the USB power on and off). Switchable
power with software would help to lower the power consumption
- the external devices would get power only when it is
