There is dead, then there is dead... If you are using Linux, open a terminal window ( in Ubuntu it's control+alt+T ) and type lsusb with just the 2 assumed dead connected. Usually you don't get the hubs listed. If 1 shows, pull 1 and try again to see which shows up. This will only show the ones that can still ' talk ' on the usb line and not anything else. With the resistor overclock not even warming it up, it looks alot like SMD rework of the voltage regulator ( U4 by the resistors for the overclocking ) may be bad on them. The dot indicating pin 1 should be closest to the USB connnector on it ( just in case in mass production on yours they got put in upside down ). The power regulator is suseptable to transient current when soldering so a grounded tip soldering iron is recomended or hot air work station. For what little cost those ICs are at places ( Mouser, etc ) it might be worth just checking that they are the correct orientation and no weird burn marks near them. Also all the pins on my ants for U2 ( the ASIC ) are clean other than the solder and can be read with the USB connector DOWN. Looking at the board, you will get what I mean. you haven't said ( and I forgot to ask ) if the red LED goes on when you plug it in.

chip is the right way round. the red LED is on and the green LED flashes (like my good ants) but in the miner window i get "AMU 0: | 2.10/ 2.10/ 0.00Gh/s " ... no accepts no rejects and no hardware error's .... maybe its a ghost ant Tongue

dead and mining in spirit only Undecided

good thinking, i am going see if i can get hold of the voltage regulators
