Topic: Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury | Ant U1 - page 40. (Read 128592 times)

As an aside, I would perfectly fine with upgrading my GPU mining rigs with ASIC mining by swapping those GPUs with PCIe/PCI-based internal USB cards, if the motherboard can deliver enough power.

you did not tell which host system you are using
=> dont forget, not all hubs work with raspberry pi.

  Take my money! Take my money!  

Jokes aside, thanks for the replies.

finlof, that power consumption explanation is really handy.

As for friedcat's store, alas, I don't understand Chinese, though I would be interested in buying that 20-port hub (if friedcat sells it, it must be compatible with the miners).

On a related note, how many miners could be powered through motherboard's on-board USB ports? I have this one: http://www.asus.com/Motherboards/P9X79/ and it has quite a lot of USB ports (both external and internal)!

And finally, what about PCI/PCIe 4-port USB cards? I have a P4 motherboard with 5 PCI slots lying around. Would I be able to power 20 miners if I put 4 of these cards in: http://www.belkin.com/IWCatProductPage.process?Product_Id=107412
It's again a question of powering through motherboard. What about equvalent PCIe cards (4x75W through motherboard)?

There's also this interesting guy, though it's on the expensive side: http://www.amazon.com/StarTech-com-SuperSpeed-Express-Power-PEXUSB3S4/dp/B005HVPYNU

EDIT: 24 ports(!) wonder if it has power enough: http://www.amazon.com/24-Port-USB-2-0-HUB-Adapter/dp/B003WPDICM

EDIT 2: This look impressive (28 ports!) http://www.thinkgeek.com/product/eecf/ , but seems to be able to power only 8 miners (5V*4A=20VA/2.5=8)

EDIT 3: To use reverse calculations, to power 10 devices, the hub would need at least 5A AC adapter. For 20 devices it would be 10A, right?

I use D-Link DUB-H7 for 5 devices and it works fine.  Output is 5.0 V DC at 3.0 amps, so it powers 5 devices easily.

friedcat has a pretty cool store too
http://friedcat.taobao.com/

The friedcat sells this hub, it seems good.




Price: ¥420.00

Don't be shilled by this fool.  Buy top quality erupter USB hubs from me at HALF the price!

Yeah there is a very special USB hub made just for folks who paid BTC1 to BTC2 for an erupter.

They are guaranteed to work perfectly with the Erupters.

They are just BTC10 each.

Let me know how many you want!

that hub will only power a max of 4 devices (and that might even be iffy), because it is a 5V 2A power adapter on it.  you need to have 2.5VA per device.  so for example if the adapter says 5V 3A then you can power 15VA worth of devices which = 15/2.5 = 6.  you really have to be careful with the usb hubs cause you could potentially mess up a device or computer if overloaded.  I bought some shitty ones off amazon that were 7-port and supposed to have a 2.5A adapter but they wouldnt power more than 3 devices.  so best to go with something that have been tried with good success.

Thanks the offer! The fan can be shipped, but the other USB hub is not shippable to my address either.

Found these on the German branch of Amazon:
http://www.amazon.de/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=usb%20hub%2010-port
Ankers are expensive!

Looks like this might be a more reasonable option (if it can power at least 5 units):
http://www.amazon.de/BIGtec-externer-10-Port-aktiver-Netzteil/dp/B004YPKVW4/ref=sr_1_3/280-5326971-4907000?ie=UTF8&qid=1373487536&sr=8-3&keywords=usb+hub+10-port

the fans are these - http://www.amazon.com/ARCTIC-USB-Powered-Portable-Cooling-Solution/dp/B003XN24GY/ref=pd_bxgy_pc_img_y
these arent laid out as well as the ankers, but I have a few of these 7-port ones and use them to power 5 each - http://www.amazon.com/dp/B003Z4G3I6/ref=pe_309540_26725410_item

i could order some and mail them to you if you'd like.

Yep, only US:
http://www.ianker.com/product/68UPHUB-B10U
Are there any re-sellers in Europe?

I edited my post while you replied, sorry. I read on some other thread that the latest cgminer had problems with those. Is that so?

Oh, and they can't be shipped to my address.

And another question: how many of those units can safely be run off a high-end motherboard's USB ports?

anker's 10-port hubs are recommended.  they will power 10 devices.

Scroll down for the lists.

All hubs in this thread were reviewed/suggested with AsicMiner's BlockErupters in mind. There is however nothing to indicate that they should not be usable with other USB 2.0 mining sticks, such as Bitfury chip-based NanoFury NF1, BPMC Red Fury and Antminer U1.

An important point brought up by Trongersoll here:

Replacement AC adapters / adapter modifications
If an AC power brick burns out, you can attempt to draw power from alternative sources, such as existing ATX power adapters or replacement power bricks. Make sure that polarity is observed and that the replacement can carry the required load. Also you should by a regulated power adapter, as explained by merv77 here. You can also attempt to preemtively mod your power feed to the hubs.
Below are a few resources, pertaining both options:

• 5V @ 5A replacement adapter, along with a few other. Reviews starting here.
• Several 5V @ 30A (150W) PSU, which is used in many modifications are listed here and here.
• A list of various PSU connectors. Useful to know, if you want to hot-wire your hubs.
• A few custom farms, mentioned in this thread: By pidge: 1 2; By bagnz0r; By merv77; Monster farm by SamHa1n: 1 2; By philipma1972; By SolidBitShop; By MonocleMan; By Photon939; By x3maniac

• A recommendation by merv77 to cut the red wire to prevent power-backing
• DC barrel plugs, no soldering required: 1, 2, 3 4

Raspberry PI resources
As Aajo mentioned in one of the replies: don't forget, not all hubs work with raspberry pi, more specifically, USB 3.0 hubs will not work. Also RPi will not support hubs, which are nested more than 1 level deep. In other words, a hub with miners, connected to a hub, connected to RPi is OK, but not anything deeper. That was my experience.
Additionally, there seems to be a limit of 49 BEs that one Pi can control at once.

Featured

• External USB 3.0: Orico 10-port @ Amazon
• External USB 2.0: Rosewill RHB-500 10-port @ Amazon and D-Link DUB-H7 7-port @ Amazon
• Internal bay: 13-port InLine® Front panel for 5.25" @ Winnipeg Technology and Computer Renewal

Prices vary greatly. I take the lowest price @ Amazon whenever possible. If you find a device at a lower price, please notify here.
For the number of usable ports, assume that the lower number of the two would work reliably, while the higher number is max. theoretical limit given the supplied power adapter.

These hubs should be OK. However, your mileage may vary

Original post:

I am considering ordering 20 of those little beauties.

Which powered USB hub should I choose? Preferably ones, which can be shipped to Europe (from Amazon/Ebay). They are going to be controlled by a PC which runs 24/7 anyway.

Would something like this do:
http://www.ebay.com/itm/Super-Speed-USB-2-0-10-Port-HUB-with-Power-Cable-USB-Cable-EU-Plug-Sliver-/400522228637?pt=US_USB_Cables_Hubs_Adapters&hash=item5d40fc339d

Anker Hubs depicted on this thread:
https://bitcointalksearch.org/topic/announcement-block-erupter-usb-195004
would probably also do (though I read somewhere that the latest cgminer fails with those)?

What are the USB fans in that picture and are they available in Europe?

If I can't get them, I plan to use something like this for cooling:
http://www.ebay.com/itm/Logisys-NP8-Laptop-Cooling-Pad-with-USB-Powered-140mm-Fan-Black-NEW-/350580671231?pt=US_Laptop_Cooling_Pads&hash=item51a03c82ff
