So I hit a USB limit in ubuntu... I have 120 gridseed 5-chip devices plugged into one linux box and getting this message: no more free ACM devices.
That is a limit of USB 2.0, 127 devices, including each hub. In theory, that is the limit of the controller, not necessarily of Linux. If all of your USB ports (on your computer) are tied to one USB controller, then there is nothing you can do - with those ports. You can try to put in a PCI-E USB card. That may give you another 127 devices off that card.

Getting rather irritated at mine. The constant need to babysit makes it a royal pain in the ass. They constantly drop out/disconnect/stop accepting shares/get bugged out in random ways. Simply having cgminer restarting now and then does not help either, as I often need to re-plug or power cycle them, as sometimes they simply disappear from /dev/ upon restart. Going to try connecting them to another PSU, try yet another hub, try connecting to another computer. Suspect shitty firmware/design though.

They've been running very smooth for 24 hours, 31 pieces deliver a steady 9,5-10 Mh/s. I'm using two raspberry Pi's. Cheap hubs and the controllers from Lightning Asic were the biggest problems with me before.

I'm using Inland 13 port USB hub. Been using it for weeks now with no chronic problems until yesterday. For some reason the ports are re-setting, or just quitting and leaving my gridseeds hanging at 'dispatching work to gridseed" mode but no results coming back as expected. Every 6 or 8 hours it seems, so far but this is only the 2nd time. It didn't do that while I was mining on LiteCoinPool.org. Started doing it after I pointed them to ScryptGuild.com - Not sure if this is the cause possibly? That's weird, if it is the cause. I'm using Win7 on an Lenovo R400 laptop. I doubt that's what's causing it.... Darn it! I thought I was good to go! CRAP! Wolfey2014

It should work i think when i did the math it was 0.6a but you would be better with 12v 5a power supply. If you over volt you destroy the gridseed example anything above 12v. If you under amp you destroy the power supply and that in turn may cause a problem with the gridseed. You need to make sure it is center positive and gridseed can use either 2.1mmx5.5 or 2.5x5.5 end.

Bought a set of 10, I hope they arrive soon
I'm going for a raspberry setup, does that thing need it's own powersupply? How many greedseeds can I hook up on 1 Raspi, I've read 20, but it doesn't seem confirmed.

Yes, and why bother? Yes, it has the necessary amps. Just make sure the BTC core is disabled. But, why bother? If you only have one miner, then steal power from the PSU on a computer. If you have more than one miner, then get a computer PSU to power them all.

I want to sell my GPUs and buy more than one GridSeed,and I can buy in my country charger such like that form amazon link under 1$ per pcs. (charger voltage is stabilized),and this is more profitable from me buy several chargers under 1$ per pcs. than 12V 5A charger or PSU.

20 with the "stock" 10-port hubs (I'm currently running that way), 26 with 13-port hubs like this: http://www.amazon.com/gp/product/B00HL7Z46KIt gets more complicated after that, since you can only have 2 levels of hubs on the Pi, and the 10- and 13-port hubs already have 2 levels inside them. Something like this might work, depending on how it's set up internally: http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6436&format=4

does anyone no if theres a DIY guide on how to make the power cords for a modular psu for these gridseeds? I read part 3 of this guide and it doesn't help me because I'm ignorant with this kind of stuff and require pics with steps lol This guide is good an i'll donate as soon as I get my miners up and running
There is a link in the op to my post with pin outs for molex and pcie connectors. I think its labeled making your own cables. The only thing I could find was the "Hacking together the power" section. That section shows how to wire up a unicorn hasher(?) up to a wall socket and connect that to a barrel connector. https://bitcointalk.org/index.php?topic=494625.msg5448809#msg5448809But I could not find how to best connect up to a standard ATX power supply. Since I'm transferring over from GPU mining, I already have 1200W power supplies ready to go and would prefer to just reuse those. Splicing the molex connector is straightforward, but not sure which is which on the barrel connectors... Any guidance on that would be great. A standard ATX power supply is easy: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi1294.photobucket.com%2Falbums%2Fb609%2Flouiemgallant%2F20140305_070934_zps36459810.jpg&t=665&c=T-jpWmuhY5iXaA) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi1294.photobucket.com%2Falbums%2Fb609%2Flouiemgallant%2F20140305_070943_zps2e8720ee.jpg&t=665&c=2SuowO1Qd2loyw) I have 2 miners atm so I am using ide molex entension cables I had lying around to power both and if need be the controller. The top 2/3 of the forum thread below has molex and PCIE power connector scematics as well as USB https://bitcointalk.org/index.php?topic=494625.100you can wire that pcie cable to your barrel connector, the inside barrel is V+ if you have a barrell connector the and if the wires are not color coded inside then on the outside on one of the black's there should be whitish-grey stripes or a solid line, it may be clear it may be faint, but this is the V+ line of the barrell connector. The link I posted above will tell u the scematics of your PCIE, but it is fairly straight forward, you have 3 yellow which ar 12V+ and 4 grounds. Do not wire a control board to this as it only requires 5V+

I'll be building an Rpi from scratch, using windows, with raspbian today or tomorrow and moving a 10 gridseed pack into a short and compact 2U rackmount chassis (20 would fit in a long 2U chassis) I'll add both to the guide. I got to the download raspbian image part before I realized I don't have an SD card reader in front of me ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)
