check for resistance in the wire and connector. Hold one probe on the sleeve of the connector (I assume you are talking about DC plugs) and then touch the other probe to the ends of the cables. The one that registers resistance is your ground or (-) wire.

Is there something wrong with this .bat?
bfgminer.exe --scrypt -o stratum+tcp://us.clevermining.com:3333 -u x -p x -d gridseed -S gridseed:\\.\COM8 \\.\COM9 --set-device gridseed:clock=900
bfgminer.exe --scrypt -S gridseed:all --set-device gridseed:clock=850 -o stratum+tcp://stratum.scryptguild.com:3333 -u x -p x Has worked for me using bfg-gridseed-pr2 from this post: https://bitcointalk.org/index.php?topic=168174.msg5617482#msg5617482For what it's worth I didn't need the custom INF files mentioned.

Put the meter into DC Volts mode. There should be two probes from your meter. One probe should be plugged into the + (pos) port on the meter. Put that probe in the middle of the plug. The other plug should be plugged into - (neg or ground) port on the meter. Touch that probe to the outside of the plug. Your meter should read somewhere between + 11.85 to 12.15 volts. If it reads - (negative) or outside the range, then no go.

hmmm you need to change /home/miner to ~ if your username isnt miner. I updated the OP if there is no autogen.sh run autoreconf -i
This is the problem code: Build cgminer: Code:
cd /home/miner/usb-miner/software/cgminer ./autogen.sh CFLAGS="-O2 -Wall -march=native" ./configure --enable-gridseed make cd
I tried the autoreconf -i from the cgminer directory, and had this error: autom4te: cannot create autom4te.cache: No such file or directory aclocal: /usr/bin/autom4te failed with exit status: 1 autoreconf: aclocal failed with exit status: 1
Since I just setup the machine, I will set it up again with the user miner. You might want to update the beginning of the instructions to add something like: "Create a user account with the name 'miner'" ...

seems like you are in the wrong directory
do a "find / -name cgminer' to locate the directory you should be in.

This may be a newbie question but is there any disadvantage to just using individual 12v5a adapters for 10 gridseeds instead of the clunky industrial power supply (apart from the cable clutter). Is the power consumption more or less the same? I have a lot of 12v5a cables lying around, so wondering if I should just use some of them.
Do they work just as well in all the three modes (sha, scrypt, combined)?
Thanks

My experience is: I've never thrown away a broken Corsair AX1200 PSU. I've thrown away dozens if not hundreds of scorched, melted, broken, squealing, etc. power bricks. That and you are most likely going to plug them into a "relocatable power tap" which is rated by UL for temporary use and warns that any protection circuits inside will simply stop working but the device will still carry a load after the expiration or the first surge event. Meaning it'll melt freely or start on fire.

miaviator set me straight with powering my gridseeds with one CORSAIR Professional Series Gold AX1200 and cables ordered from startech I'll be able to power a whole bunch of these little buggers...

I do have a spare CX600 lying around which judging by the power requirements should be okay for scrypt only.

These changes were made to the OP as well some things I found last night helping xmk3. richmke let me know if the updated instructions give you any issues.

A total of 10. I know I really should use RM1000 or AX1200 (have both, but they are running me ants :p)

It's positive center. Use a multimeter to check your wiring, don't rely on colors. Yeah, red/white and power is only applicable to the cables from asiabtc/lightening asic. I should edit that.

https://drive.google.com/file/d/0B2X-bj_TJfWQZk81Y3h1Ukk1WHc/edit?usp=sharingcan anyone tell me what I could use to connect 8 Gridseeds to 1 connection of the powersupply it's the questionmark on the diagram does it matter that the load is not spread completely even? 9 gridseeds / 9 gridseeds / 8 gridseeds ? Also: if any stupidity is found in that diagram, please let me know thanks

how can you check polarity of a cable with a multimeter?
check for resistance in the wire and connector. Hold one probe on the sleeve of the connector (I assume you are talking about DC plugs) and then touch the other probe to the ends of the cables. The one that registers resistance is your ground or (-) wire. So the outside of the plug should be connected to the white cable, which in turn should be connected to the -V of the powersupply so normally putting one probe on the outside (sleeve of the connector) and the other at the end of the white cable gives me a reading on resistance putting one probe on the inside of the connector and the other at the end of the white cable gives no reading ?

The ? is a "bus bar". Something like this: http://www.amazon.com/Blue-Sea-Systems-DualBus-Terminal/dp/B000K2K6M0The wire from the PSU to the bar should be heavy guage (low number, 12 should work, 14 might) to carry all the current. Or, you can use a heavy gauge wire to the "?", and join all the wires together (soldier them). If the joint is getting too big, then daisy chain off the heavy gauge wire (connect two pieces of heavy gauge wire and, say 3 gridseed wires, at one connection, then repeat - with one end of the heavy gauge wire going to the PSU (or prior joint), and the other end of the wire to create a new joint. Kind of like how a PSU puts 3 molex connectors on one wire. does it matter that the load is not spread completely even? 9 gridseeds / 9 gridseeds / 8 gridseeds ?
9/9/8 is close enough for balance.
