LOL.

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

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

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

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?

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

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

LOL!

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.

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.

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.  Cool

It is the power of USB 3.0 that you want, not the protocol.  Erupters negotiate to USB 1.1.
I don't think you'll find many USB 2.0 hubs that can supply 5A @ 5V, 0.5A on each port.  Most have few "charging" ports, the rest is 100mA ports.
Most have 3.5A or 4A @5V power supplies.

Anker is an exception with 4A @12V.

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.

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.

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.

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

http://www.amazon.com/Anker%C2%AE-Uspeed-10-Port-Adapter-Chipset/dp/B005NGQWL2


i prefer the black

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 Smiley

ANKER hubs can take 10 USB's easy
