anyone running minepeon on a pi with this compac plugged in?

i cant get it to hash over 3ghs
it is in a powered usb hub 2.0 5v4a

if anyone has a step by step so i can see if i  missed anything.

or if you have a better idea on how to go about setting up the pi to work... im open to any ideas

best way to start is to check at what V the core chip is running.

So get your favorite multimeter and verify using ground + vcore pads at the back.

then force it to run at 150Mhs for a start.

and then take it from there depending on your usb hub W per port.

Check this for speed / W correspondence:

Thank you good sir!  I've been struggling to reach ~18 GH/s each on ten (10) of these, and I finally managed it with your advice

Hi Everyone,

I got my EU version of the compac through from bitshopper.de to play with and I have an interesting issue with my stick that I'd appreciate some input on.

I can get the stick hashing ok from BFGMiner since it doesn't get detected by the novak version of cgminer but I have read that this is a known thing so that doesn't really bother me.

Then things get interesting as it will sit happily at around 10-11 GHs and then after what feels like a few minutes the hash rate starts dropping down slowly to zero so I started to investigate.

I got my mains plug power meter and stuck that between the wall socket and the power supply for my admittedly crappy (!) USB hub and when its hashing its drawing about 7.1W from the wall but then it drops out to hardly anything when the hash rate starts dropping and putting a DMM on the stick reveals that I have no vCore voltage when this happens but the rest of the voltage rails check out ok!?

Has the stick upset my crappy hub and activated some sort of protection? Taking the USB and power off the hub and plugging it back in restores the vCore on the stick and it will hash again which is making me think its the hub doing something.

The hub is powered by a 5V 2A wall wart style power supply.

I find it interesting that the power is still going to the stick since the green LED stays on and I thought if a USB port "trips" due to power consumption it cuts the power? or perhaps it limits the power?

Do you think a USB Y-Cable would sort the above if its a, per port on the hub, power related issue? Maybe I need a new hub?

You could try downclocking for the time being see if it stay stable. Also a Y Splitter is nice and cheap. (paid 1$ for mine)

Why not go back to cgminer and use Zadig to fix the driver issue as instructed in OP?

[zOU]

What is your VCORE set to ?

[ChEd1980]

My VCore is showing as 0.69V

I am starting BFGminer with this switch: --set compac:clock=125

I'm not entirely sure if BFGminer is looking at that or not as 10ish GHs is not what I'd expect for 125MHz unless I am mistaken?

It would indeed be lower, but i'm not sure how BFGminer handle the gekko compact. Maybe it ramp down or something. Use cgminer as per OP.

You have to use hex value with bfgminer (I'd recommend cgminer as well, works good for me ):

Note that for bfgminer you have to use the hex value for a given clock rate, whereas for cgminer you specify the clock rate in MHz.
A table of values to use in BFGminer is as follows:

        { 106.25,       0x0803 },

I think that current bfgminer (5.4.1) can handle integers for frequency, but I digress.

[sidehack]

BFG 5.3 requires hex; BFG 5.4 works with MHz. cgminer-gekko uses the product ID info in the CP2102 on the stick to identify the Compac, and we forgot to make sure it recognized bitshopper's custom ID. This has nothing to do with drivers. Novak's been busy with a couple other projects and hasn't gotten back to the cgminer code so it's still a known issue. 125MHz should run you just shy of 7GH.

So if you understand double dutch you'll be ok .

Yeah .

[ChEd1980]

Thanks guys! 

I'll ramp it down a few notches which will hopefully make it use less power, if that is what is causing the upset.

Last time I was testing I was using bfgminer 5.3.0 which might explain a few things as to why it wasn't running at the speed I tried to set...doh!

{ 125, 0x0983 },

Ha ha sounds like you need to use 0x0983, try it and let us know how you get on .

You should be ok to use 150 / 0x0b83 without additional cooling.

I'm running 6 @ 300MHz / 16GH with cooling now very stable .

Hi, just to let you know I have 3 of the green heatsink ones for sale HERE: https://bitcointalk.org/index.php?topic=1282154.0

Also I would just like to point out that this is UK only unfortunately..

Thanks

earlier i asked about this miner and haven't been able to make it work.. time is passing without mining and having this thing in my hands..

for most simplicity, i'm testing using windows 7 home premium.
using BFG-Miner 5.4.1 (supported since 5.3 right?)
miner from bitshopper.de
i search cmd and right click to start with admin rights.
go to directory, and start bfg miner with:
bfgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -O 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --set compac:clock=0x0783
NO DEVICES FOUND. (press M + auto or all finds nothing)
in device manager i do see: Compac BM1384 USB Miner
Hardware ID = USB\VID_10C4&PID_EA60&REV_0100

Should this thing be like "plug and play" or do i need to install some drivers? I have also tried winusb zadig drivers but still no fun..

Starting to get desperate and i'm really thinking if i received some faulty thing..
it's been like 2 months since i received it, and everytime i have some spare time, it just won't work...
must have used up like at least 12 hours on this thing... grrrrrr...

Hope someone can see what's up.. and give me some clear instructions..

wrong drivers to start with
use these http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx  , windows should download them for you, even win 7,  but it looks like the wrong drivers for BFG, and it should be  plug and play once you have bfg setup. but it's not all ways.

[Genzetsuei]

To start with your drivers.
You are damn right!

it seems to work now! I must have been blind!
Strange that it did not install this driver when i put the usb in?

I started on a macosx, then linux, and as a last resort on windows.
I'm going to try this on the other platforms since i just installed windows to test this.

What drivers are needed on linux or macosx?

Thanks Toptek for the advice!

[Mikestang]

--set compac:clock=0x0783

Also, besides the driver mentioned, you should use integers for the clock setting in 5.4.1, not the hex value.

so, got a new usb 3.0 hub (tp-link uh720), but can't get the bitshopper-version working in bfgminer on rpi b+.
usb 2.0 hub worked fine but was too weak. any suggestion?
