I have read https://www.raspberrypi.org/documentation/hardware/raspberrypi/usb/README.md

It probably depends on the usb-interface on the peripheral-side.

I have got a Raspberry Pi 2 running Ubuntu with an USB-harddisk, 3.0 that is.
Without any problem.

Maybe it helps to set max_usb_current=1 ?
http://raspberrypi.stackexchange.com/questions/27708/is-setting-max-usb-current-1-to-give-more-power-to-usb-devices-a-bad-idea
That's what I did because of the harddrive.

nice find!

Ive been putting off a hub because I want usb 3 + fairly high power that would work with compacs, portable usb 3 drives and compatible with rpi.

now I have no excuse not to get one

btw which rpi (sorry if you mentioned it previously)?

Most likely a problem with your USB hub (insufficient power?), or a defective USB controller or device.

That actually looks like a qualified powered hub!

I've been testing 1 of these for the last 5 days, got it plugged into a USB 2.0 hub that's plugged into the RPi running Ubuntu 14.04 LTS (for the Pi's), with 5 sticks at 325MHz.

http://www.amazon.com/gp/product/B013OK10YM?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

In 5 days I've gotten 2 HW with A 9676736 and R 4544.

EDIT: For a quick check, I just now plugged the Superbpag 7 Port Portable Multi USB Charger 70 Watt 14A with USB 3.0 Hub to the Pi, and it looks like it is working.

So I'm going to let it run for 24 hours and see how it go's at 325MHz.

What does that mean exactly?

Does the software of bfgminer work? or is it something specific on my end you can elaborate on?

thanks!

Well, i'm about to give up on the RPI as an ASIC controller/miner.

I've installed ubuntu on a old laptop with a dead screen and I'm currently installing minera + cgminer/bfgminer.

That will allow me to hook up USB3 hubs.

That being said:
Better a USB3 hub (orico A3H10 looks fine)

Or something like these (using a Y cable for the compac sticks)

Thank you for your advice

That's what I expected. Probably nothing I can do in software then.

sidehack, in these images, are they proper concerns?

the one that just drops the hashing:

^{img1 bad solder?}
Bad soldering on the CP2102


^{img2 bad solder?}
Looks like you had a second suck of the sav on this chip?

as for the one that slows down the hashing:


^{img3 bad solder?}
looks like it may just suck up the solder under it..

also:

^{spotted that last minute modification you mentioned..}

You're lucky, mine are not even detected on my RPI (and they work just fine with cgminer)
./bfgminer54 -S all --set compac:clock=150 -o stratum+tcp://solo.ckpool.org:3333 -u bla -p bla

There were a few post's with this error and I can't remember for sure how it was fixed or if it was fixed. I think it was changing the bat to -S all --set compac:clock=150

well, I spent 2h this morning getting all 6 at 150Mhs on another Hub (Orico P10 U2 12V/3A http://www.amazon.com/ORICO-USB2-0-Adapter-3-3Ft-Desktop/dp/B00EH44AA6)
Got 1 HW and 2 RE in 45mn after that, so I'm pretty happy.



@chiguireitor: what hub are you using ? What V are they set to ? Any special cooling ? I suppose your using USB Y cable (2males/1 female to get enough Amp... ?)

You gotta fine tune more, i have them all running at 375Mhz with 0 HW errors.

Yes ive tried the both no luck yet.

Can you tell me what that werr code is with this custom build?
http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=tmp3933

Comms error (werr=1): seems to be a write error.

Have you tried the special cgminer version in the first post ?

What is the V setting on your sticks ?

Hi,

I'm running BFGMiner version 5.4.0 64bit on win 7 64bit ultimate.

I am trying to run the GekkoScience Compac UBS's in a powered USB hub.  I have 5 of the USB miners.

I'm using an Anker 10 port Powered Hub: http://www.amazon.com/Upgraded-Anker-SuperSpeed-Including-Charging/dp/B005NGQWL2  mor from the manufacturer: http://www.ianker.com/product/68ANHUB-B10A

I keep getting this error:

CBM 0: Comms error (werr=1)
CBM 1: Comms error (werr=1) 

I had 1 USB miner in the hub and got those errors then it started to go away.

The first one was hashing at stock about 8 GH/s and the second the same

I ran a .bat file  as follows:

bfgminer -o stratum+tcp://stratum.antpool.com:3333 -u xxx.x -p x --set compac:clock=0x0b83

I also tried:

bfgminer -o stratum+tcp://stratum.antpool.com:3333 -u xxx.x -p x --set compac:clock=150

I am not sure why im getting this error.

I did also try the cgminer version and ran zadig, but that didn't work for me, so i removed the zadig driver.

I just removed the second compac and im still getting the errors.

it seems as if it accepts once in a while.

Does anyone have a fix for this?

thanks!

OK, plan for tomorrow.
Run cgminer
Plug 1 compac
Adjust until stable
Add 1 compac
Adjust until stable
Repeat until all 6 are stable

0.55V at 150MHz is very impressive, best I have reliably done with an R1 is 0.61V.
