Title: is anyone using a 49 port hub and Raspberry Pi? Post by: silicon64 on December 04, 2013, 09:50:53 PM Trying to find out if anyone is using a Raspberry Pi or a BeagleBone Black with an AsicMiner 49 port hub?

Hi, The com port limitation on the Raspberry Pi is 28 ports so it is not a suitable controller for a 49 port hub. I don't know about the Raspberry Pi B+. That might be different.

Post by: Ghostface on September 01, 2014, 10:41:21 AM There's a mining help section here that would probably be more help for you and get you an answer. You should ask over there. I believe you can move thisn thread yourself if you wanted.

I have been around for a while in mining. I can say I have not seen it. With RaspberryPi i think your asking alot on 49 port hub, but I could be wrong. Best off with a low power desktop.

Post by: klintay on September 02, 2014, 12:26:33 AM I am 100% certain it is not possible because of the COM PORT limitation (i.e. there limitation on how many usb devices can be plugged into a raspberry pi, even if you have a usb hub) on a RaspPi. You could connect it up but you would only by able to control 20 ports or so...the rest would not be recognised. BananaPi or other device might be different.
Title: Re: is anyone using a 49 port hub and Raspberry Pi? Post by: xjack on September 02, 2014, 08:40:57 PM I used to run a BBB rev B3 with a 49 port hub. If I was doing it again tomorrow, I'd use the debian build. Angstrom sucked for getting the libs needed for mining. I suppose it's possible the builds today have libudev installed.
Here's a snippet from way back then. If I recall correctly, stability wasn't there with 40+ usbs. I eventually went to a linux nettop controller - it ran 118 usb miners and still runs 24/7 almost a year later (usbs are long gone). The BBB is collecting dust. I'm sure RasbPi would be in the same dusty box if I owned one. ...snip... Update and bump for this cool platform. I've been playing around with the BBB and the mineninja image and through dumb luck managed to get cgminer 3.4.3 to compile and run. ...snip Neither libudev nor udev-dev would install, seems to be an issue with BBB or Angstrom. After banging my head against the desk trying to figure out how to install libudev, I found a google group post for a BBB libudev problem. The BBB group post recommended systemd-dev. After I tried it, smooth sailing. opkg install systemd-dev libsub-1.0.16-rc10 - http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.16-rc10/ Compile CGminer 3.4.3. ...snip... YMMV. Have a backup. I messed with udev and libudev for quite a while figuring this out. I have not reflashed the BBB to recreate the solution. Seemed pretty happy around 50-55 erupters. Really dogged out over 60 and crashed at 66. I ran 48 all night on the same hub which previously gave me problems earlier in this thread. My experience - you can make the BBB work. But a 50 watt ubuntu box will work better. |
