Hi, i had 5 of the compacs running, then switched a few around for better airflow, and 1 of the 5 wont start to hash - (it was previously)
The green light is on, nut no blinking.
I started with a different USB 2.0 powered hub- it was from the old BUYAHASH I found in microcenter which claims to be able to push at least 1Amp per port, and was running in cgminer fine. - unsure of how its able to push at least 1 Amp per port? it is 5Amps total i think?
here is the link to the hub page at microcenter and a breif description:
http://www.microcenter.com/product/431863/10-port_usb_20_hub_w-_power_supply"Need a cheap, high powered hub?This is the best one weve tested that is compatible with Raspberry Pis and other devices that require the older USB 2.0 protocol. Made by the same manufacturers as our 20-port hub, this model is noticably cheaper, while still ensuring that every port gets the power it needs.Included is a 12v/5a power supply, USB 2.0 cable, and hub. This model is designed for ports that require a high amount of electricity, and should be able to provide at least 5v/1a, or greater per port."SKU 198192

Then connected the ras pi running the modded version of cgminer for the compacs and all 5 were fine and hashing.
Is there a way to reset that one that doesn't hash now?
I am just running them at freq of 175 and the potentiometer is top left corner on each (flat part)
The other 4 are hashing at around 9.5 to 10 GH/s each
thanks!
I think even if your only running at freq 175, with where you said you have the pot set, your pulling more power per stick than you need, so it could still be a power issue. The 4 are using up enough power to keep the 5th one from hashing.
Pull 1 of the stick's that "is" hashing and see if the 1 that's not hashing starts to hash. If it does, you know it's because of power.
