I'm getting 50 (and more in the future) USB miners. What USB hub should I get? No idea what is good these days.

anker?

edit: for some reason, I thought you were trolling me with a random word. Googling shows up a bunch of usb 3.0 hubs. I heard USB miners and cgminer/bfgminer have problems with usb 3.0 though. Is there a usb 2.0 hub out there thats reliable?

the anker 10 port 3.0 usb, it powers 10 hubs, tried and tested... does not work on a PI apparently

i prefer the black

Hmm,that power supply is 12 volt, but I thought USB was 5 volts? O_o Which is it?

I don't want to fry my usb miners.

does not work *directly*, but if I have a 5-port hub with 5 ankers attached, it *should* work, no?

really don't know..... i never got round to setting them up on my PI, but i had 8 anker hubs with 76USB's attached to my laptop at one point :)

ANKER hubs can take 10 USB's easy

The Anker works fine on cgminer 3.1.1 in Windows with the COM Port Drivers.  RasbPi is a no, and Linux I'm not sure.



Single cable solutions are my kinda thing, so I hopefully lucked out since I just bought this 2.0 powered hub very cheap (less than $5 per port). I'm hoping it works on the RasPI with the included 400-watt PS.  I may not ever fill it due to ROI, maybe when the K1's come out.

try this

exsys ex-1177hmv

I use Ubuntu 12.whatever LTS and the 10 port Ankar works fine with 7 USB ASICminers and a fan. It will work fine with 9 USB and a fan. Yes there is a problem with the Pi. apparently, the miners are USB 1.1 or some such, the hub is USB 3.0 and I think the Pi USB 2.0. Somewhere along the line one of them gets confused.

Regardless of what the Ankar's power brick says on it, at the USB plug it is 5.5v, it will not damage your miner. Which machine you use to host your miners will determine what you can use. If it isn't a Pi then the Ankar will work fine. That is what most people use.

For me cgminer 3.2.x and higher (running in raw USB mode) has intermittent problems with USB block eruptors on the Anker hub. A device would randomly zombie out, and suddenly reappear as a new device. Shortly thereafter cgminer would crash.

However, cgminer 3.1.x which still communicates with Icarus devices in the serial-USB mode seems to run just fine. I am guessing that it is only a matter of time before this gets sorted out.

Where did you find this so cheap?

The only place I can find to buy it is asking over $1,000 usd

That USB hub is badass, I want one!

Bought it gently used.  8)

Does anyone here suspect this would be a problem powering up 9 erupters and a fan? http://www.rosewill.com/products/1543/ProductDetail_Specifications.htm

I think, generally speaking, it's the power supply that comes with these hubs that determines how many erupters can be powered up simultaneously, and not so much the hub itself.

Pahahahaha...kneel down before the king;

Sorry xjack, she can'na handle the raw 80 port USB PWR!!!

This may be slightly off topic but...

How hard would it be to make a powered USB hub yourself? In the simplest terms all you should need to do is open up a non-powered hub and connect all the USB power contacts to a separate PSU capable of supplying the correct voltage/amperage. Then even connect a few together and make your own 49-port hub. granted it may not be a nice looking but for $1000 it might be worth it.

Just a thought.

The 80 port one above is $169.

The 49 port for over $1000 is presumably priced and sold by Fried Cat.

The 80 Port above charges only, no data.

:'(

Got this one as a backup too. $5 for 7-ports!

400ma? will it power even one device?

LOL! 

I have a USB 3 hub going into a multi USB PCI card in an old WinXP rig which has been the most stable setup I've tried.

I like the 3.0 since they have more power per port but perhaps they work better when having to convert back down to USB 2

food for thought

No matter what USB hub I buy, I need to make sure to have an extra USB port for my new toy:

Notice the USB male plug is blurred... rofl  :D

Lol.. I found this while doing research into the 49 port hub.  8)

LOL.

If they ever make a 256KB flash drive out of that, I'll totally keep a wallet.dat on it.

maybe this one

That was my initial choice. Here is another link to it with specs: http://www.thinkgeek.com/product/eecf/#tabs

Power Adapter
cUL, FCC
Input: 100 - 240 V, 50/60 Hz; 1.6A, maximum
Output: 5 V / 4 A
Cable: 1.2 m (6 ft.)

Only enough power to run 8   :'(

Ahhh, good catch and good to know

ports look like they are too close together to be side by side.

will either one be able to run  ~20 erupters?

See the bolded statement above... it only runs 8.

The best solution for 10+ I've found so far is the Anker linked in this thread earlier.

Maybe this if you want to rack them  :)

http://usb.brando.com/industrial-usb-16-port-hub_p01936c039d015.html

the anker USB 3.0 hubs are the best if you are not suing PI.... you can run 10 USB on each hub. I had 76 erupters set up on 8 anker hubs via windows running on bfgminer perfect

16-Port Hub: Up to 16 hubs are provided for USB connection like printer, digital camera, card reader, MP3 player etc
Fully compliant with USB 2.0 specification
Backward compatible with USB 1.1
Input: 100-240V AC, 50/60Hz, 0.5A
Output: 5V DC, 3A, 15W
Dimension: 169 x 118 x 38mm (approx.)
Weight: 310g

Package Contents:
Industrial USB 16-Port Hub
USB Cable
Universal AC adapter


again 5v...... cannot run more than 8..... the anker is the best

^ Looks like it has 2 DC input ports.

Makes me think that you can use 2 5V/3A adapters to get 6A meaning it can run atleast 12 most likely 16.

yes you would most likely need an additional power adapter to get the hub fully powered.

oh boy! fap fap fap

4.5A @20V = 90W

Looks nice.
Is this charging port also data connected? This 2.1A would be perfect for powering the cubieboard (http://cubieboard.org) i guess.

No it only provides power. You can use it for a fan though.

There you go:

Can u post a link to where you got it?

Picked up one of these the other day for my Gridseeds:

It was ~$20 in-store at the time.  Amazon didn't have them...don't know where else you might find them that might be cheaper.  In any case, it's a 7-port hub with a 3.6A power supply bundled with it.  Instead of the dinky 1.35mm (?) power connector you see on most hubs, it has the same 2.1mm connector that the Gridseed miners use, so you could pull an unused 5V output from your power supply and run the hub with that.  I expanded from 6 to 8 miners today, so all seven ports are in use (plus a port on another hub).  So far, all's well and it's cranking about 2.75 MH/s.

I have 3 of your 19 port hubs.

If I buy the bridge above what would it supply to

this usb miner?

 1.8 amps?

Hi.. I just want know if ANKER 3.0 is compatible with my gekkoscience 2pac? or is there another brand that of usb hub that i can use for my gekko?.. thank you

How in the he.. did you find this ancient thread?? Especially considering there is a much newer one specifically for the new sticks where you will find your answers...
Now that usb sticks are being sold by sidehack here is a new usb hub thread (https://bitcointalk.org/index.php?topic=1779423.0)
