they wont hash. i had all 4 running. one i messed up and it only hashes at half speed. the other ones idk what happened but they just time out. i now only have 1 full hashing board.
If they do not hash but simply timeout, then cgminer debug won't have anything for you either.
For the ones that don't hash:
1. When they are connected, do they flash the green light and timeout at the golden nonce or do they report an error code?
2. Were you running them without a heatsink, and if so, did you have a fan blowing over them?
EDIT: Also, what setting(s) were you using?
3. Plug all of them in and check Device Manager (windows) to see if they all appear as whatever driver you chose or HID devices. If they appear as Unknown, then it may be a driver issue (long shot, but lets cover our bases).
when i came home from work one was hashing at ~10ghs. i unplugged the usb converter then power cycled it and plugged it back in and no hashing.
1. no flashing, just golden nonce, no error
2. the chips have small heatsinks on the front and were placed on something for heat transfer through the back. i also had placed gridseed pods on the heatsinks on the chips with fans running
3. they come up as cp2102 usb to uart converter.
side note when i plug in a uart converter with out being connected to a blade i get the golden nonce.
both non working boards have .8v across the board and the first chip has 3.3v, so maybe the crystal?
