Some how it's hard to know unless you open the hub & check the chips type.
Or you can mail the manufacturer about the chip.

And do not used the original dc supply. Get the power from your PSU.

I will research, thanks.

Yes, I have them running off a 850w psu with an S1, thanks.

I mean get the power for the usb hub from 850w psu too

Why would that make a difference?

Depends on the exact USB hub, some come with pretty lame power bricks.

Check you powered usb hub chip. Is it STT or MTT chips?
You need usb hub with MTT chip.

How would I go about doing that please? It's an Ensignia brand from BestBuy, model number NS-PCH5421, 4-port USB 2.0 hub. 5vD.C. ~100mA, thank you.

I've had great success running one of these units. I have it on a powered USB 2.0 hub and use a molex 4-pin to barrel plug of the 850w psu my S1 uses. Using cgminer 4.90, 775v 237.50mhz gives me a super stable ~57.5gh.

Did you ever try getting more than one running at the same time? I bought two more U3s, but I can't get more than one of them to run at the same time; any of the 3 run fine by themself. Using stock volt/freq for all of this, I've tried launching cgminer with 2 plugged in at the same time and I get constant LIBUSB from both devices. If I unplug one the other runs just fine. If I launch cgminer with just one running it hums along perfectly, then I'll hotplug the second one in and instantly the LIBUSB errors start. I've tried with them both plugged into my powered USB 2.0 hub, and tried with one in the hub and the other in a separate USB port on my computer, but no matter what if more than 1 is plugged in I get LIBUSB errors. Any ideas?

I got a brand new U3 straight from Bitmain over amazon. Have been fiddling with it all night and can't seem to get it recognized by CGminer. I have done all the steps and don't know what else to do? Any ideas would be helpful.

My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)

I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.

My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"

When I start CGMiner it says "No Devices Detected"

What am I missing? It seems to be recognized by my computer, but just not by CGMiner.

Maybe start CGminer THEN plug the USB in Wink

That's how CGminer worked for the little gridseeds,at least for me Roll Eyes

Yeah that's one option, apparently hotplug has a better chance of detecting devices. Are you plugged in via USB 1.1, 2.0 or 3.0? Are you putting it through a hub at all?

Ok, I can try that when I get home. I have tried it on my main desktop through USB 3.0 and 2.0, then on my little netbook that I used to run all of the AsicMiner USB devices, which should be 2.0. I am not using it through a hub, I can try that too as well though.

Don't use USB 3, it uses different drivers / something else that usually prevents it from working. Powered hub can help with dropout issues as there is a reasonable amount of 5V load.

So how quiet are these miners? (can not find any video with this miner) im only after quiet miners. i did see that Bitmain came out with a new design on them.

It looks to be exactly the same fan, so it then depends on what your definition of 'silent' is. To me they're as quiet as ambient, but its personal opinion.

These new ones should get a little more air because of the new design maybe run a little colder and fan speed may not need to be so high. its just a thought...

after some tinkering i got minera to work with some ease. Minepeon is to outdated to work with the U3 out of the box for anyone else looking to run these on a pi go with Minera and change from default of CPU miner to CGMINER on the latest version 4.0.0 works with only those changes

Any good recommendations for a raspberry pi based controller that supports the U3?

Raspian, Minera, MinePeon, anything that will get you cgminer.

I am familiar with minera for Gridseed devices but was unable to get it to detect the U3 I was offering this as a suggestion for a future guide from you if you had time to put together a setup guide for Running the U3 off of the Pi to expand off this setup guide. I have also tinkered with Minera but the latest build has an outdated cgminer and wont detect the U3 and the bfgminer works but only hashes at 4GH. I am still tinkering but no clean off the shelf solution to run a Pi with the U3 yet without some tinkering

I still go for Raspian because its essentially just a linux environment, so you can put whatever cgminer you want on it. There are obscenely long instructions for that in the Noncetech guide if you want to go from scratch, although other users may be able to provide nearly complete SD card images for Raspbian.
