They will draw about 60mA

They will draw about 60mA per device when running at full power on all channels. USB maxes out at 500mA per port, so don't exceed that. The ShiftBrites have an internal regulator that wants over 5.5 volts, but they can run on USB 5V if you bridge the solder jumper provided on the PCB for that purpose.
