I connect 9 sets of AntMiner U3 to RaspBerry running CGMINERR via a powered USB hub.
The strange thing is, also CGMINER detects 9 USB devices, but only 8 devices are working. Pls advice what is actually going on?
CGMINER shows
"9 total known USB devices."
Hotplug interval: 5
8 USB devices, 8enabled, 0 desiabled, 0 zombie"
Thanks very much.
