Topic: Block Erupter and Raspberry Pi (Read 12275 times)

Just done a couple of mods to my pi to get it ready for a single BE.

Drilled the lid and created a fan mount, and a little breakout board for the GPIO 5v which the fan is plugged into. Fanf floats right above the USB port. Power mods; bypass all polyfuses and add direct power supply to the USB ports. You don't really need a powered hub

Which Rosewill 10-port powered hubs are you using? (they have 4 different models, more like 3 since two of them are just different colors).

My RPi Model B (v2) has been powering a block eruptor directly without problems for over a month now. (Plugged into a 2A USB outlet)

Dlink DUB-H7 arrived today; plugged it into Pi and seen exactly the same behavior I've seen before.

Downgraded to cgminer 3.1.1 and everything works great, USB sticks seen as ICA0..3

I guess the issue is with cgminer direct access to usb port. 3.3.1 doesn't work, 3.1.1 works.


topology looks like this:

Switch back to cgminer version 3.1.1a and I think you'll have better luck. 

my pi doesn't work with any hubs I have.

I have old trendnet and some noname usb 2.0 hubs, both have external power. pi detects hubs and 'lsusb -t' shows correct topology. sticks run for 2-3 seconds, then I see hashrate drop and then pi hangs when I kill cgminer. then, hardware watchdog reboots pi and I get to try again. I can run my sticks on PC just fine using any of my hubs. I ordered DLINK DUB-H7 hub - this one works with pi, i've seen many pictures online proving that.

i will post more when I have updates

No, the maximum power the USB port of a Raspberry Pi can deliver is 100mA.
There is a fuse that blows if you ask more.
You need a powered usb hub.

Maybe (depending on the voltage) - I had a rPi+BE running, but using a 2A/5V Power Supply, 1.2 might be high enough ... W=V*A

For stability and ease-of-remote-reboot, rPi+PoweredHub+BE(on hub) would be the way to go

No it will not.

Hey everyone, would the raspberry pi offer sufficient power to run 1 USB Block Erupter?  I will be receiving my first device later this month, and plan to use strictly one unit with the pi for a while.  I currently use a 1.2 A usb power adapter for the raspberry pi.  Thanks.

you can stick 3 erupters on each side, then you have one  ampere reserve (6 sticks = 3 A)

I was looking at that one before.. couple different manufactures have it.. the usb ports themselves look way to close together..

does this hub

work with raspberry pi?

I'm waiting more Erupters from www.asicminer-shop.de
I hope will lunch 16 Erupters on my Raspberry before WE.
Currently 10 work just fine:

BTW I'm selling this ANKER HUB now (working with Raspberry, used ~ week):

https://www.bitmit.net/en/item/48972-anker-usb-3-0-10-port-hub-with-12v-4a-power-adapter-4-raspberry

I discovered this Rosewill usb hub, RHB-500 http://www.rosewill.com/products/1543/ProductDetail_Overview.htm, that might adequately power at least as many as the RHB-520 due to its power supply giving 4A. And it's not a USB 3.0 hub so I suspect it'll play nice with RPi as well. Anyone have reason to doubt its suitability?

Sorry, I'm only seeing this now.

I think Rosewill is newegg's in-house brand. Mine is a 10-port, 3.5A (model RHB-520). There's a switch to enable all 10 ports or just the first 6, but I'm not sure if this causes a drop in the first 6 ports, so I've left it off. 6 was fine for me, anyway, as I only had 5 erupters and the pi.

For the record, that specific Rosewill hub wasn't listed in the RPi compatibility charts, but another Rosewill model was. They probably all work.

Damn, Thanx for letting us know...I`ll try a few things when my hardware arrives....

I have tried this - no dice  :/

I have ordered a hub that looks like the Anker Just a thought, has anybody tried a usb 2 hub between the Pi and the Anker, Would this work?? Pi-USB2-USB3

I ran two USB Block Erupters, and the Raspberry Pi of the same hub (D-Link DUB-H7, power the rPI off on off the charge ports. Hub does not backfeed on the uplink, so works great with the pi).

Only problem is that with the current minepeon, only cgminer runs the Block Erupter, and only bfgminer runs the Jalapeno. So I moved my Block Erupters to my main computer...
