Part 7: FAQ and things that need to be added
Q: I get ttyACMx vs ttyUSBx and no shares are submitted even though the miners work and pull from stratum
A: This is normal. Some linux versions may give you ttyUSB vs ttyACM. Shouldn't matter. Post if it does.
Q: Cablez's page he mentions several sizes/types (2.1/5.5 vs. 2.5/5.5)
A: 2.5mm plug

Plug # 11 is for the USB HUB !!! Awesome!
Q: Would you consider using Cablez's micro-USB to ATX PSU power cable as well?
I've never seen that, I'll put an order in and Yes!
Q: One thing though... You say to throw away those PSU's that come with it and get a modular PSU capable of 600+ watts
A: I just buy modular cables from cablez here on BTC talk. He can make just about anything for any power supply. I plugged all 10 gridseeds and the hub directly into my corsair AX1200 using custom made modular plugs. You could keep the included PSU's or use a really low wattage PSU to only run in scrypt mode.
Q: my devices won't mine and syslog spits out a bunch of modem manager lines:
sudo pkill /usr/sbin/modem-manager
sudo apt-get remove --purge modem-manager
Q: When I start cgminer/cpuminer/xxxminer no shares are submitted and syslog spits out some weird errors and I get these errors. And libusbnot

Q: can xxxminer based on cgminer tell me how many devices are available?
