Topic: Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury | Ant U1 - page 8. (Read 128597 times)

Absoluteley!  Plz contact yxt

But can we buy one in the UK?

@ Nemo, I think the current cost per port is 0 if buying 50 units...

OP shows Cambrionix is on the special list.  If it is on the beware list, mine works flawlessly on xubunutu since July, also works on BBB - Windows was a little flakey.  The power supply it comes with is a beware, a 10 year old Antec Trupower rectified the power problem.

Can you please post link to thread with some review?
Also will this ASICminer hub power up usb 3.0 device ~0.9A ?
Usb 2.0 is limited to 0.5A only.

LigilLnk in the warning list was added at a later point, when it was discovered that it's a clone of BigTek, where all the same warnings apply. It's unreviewed in the main list, so I'll remove it from there.

It might be a good option to buy, if you plan to mod it. Read the posts of guys who did that.

Thanks again Nemo I should have this all fixed up today, hopefully. Ill post some pics and maybe it will help someone else with some of the same questions.

Guys I'm confused... I'm looking at a cheap option to run 40-50 miners (about 40 BE and 5 or more BlueFury's). I was about to order 5 of the 10port TeckNet's from Amazon UK which would cost me about €215 inc shipping (to NL)

However, there's a shop in NL who sells the LogiLink 10ports (UA0096)

When I look at the lists, the LogiLink one appears twice. It's at the featured list, stating it can run 6 to 7 BE's (with the supplied 3.5a power supply) but at the same time it's listed at the warning part where it states it can run only 2 or none at all.

When I order 8 of them (aiming at around 50ish usable ports) it will come down to around €140 inc shipping, maybe add €10 for an extra power divide box (whatever they're called in English) to host all the power cables. Still, it's way cheaper than the TeckNet's.

The shop selling them has this 14day return policy (without giving a reason) so it's worth a try. However, I'm a bit worried about the experiences people have here with this hub, burning out, melting, etc.

So... what to do?

And at the same time, depending on the answers here, maybe the first post needs an update as this hub is listed twice.

Nice! I've added it to the Special Hubs section. However, I am still trying to find how much they cost by themselves to calculate price per port, or do you need to by 50BEs to get a hub?


It depends on how well your ATX supply delivers on the 5V rail. I mentioned it before that I have 2 different ATX'es with 25A on 5V., and the older ATX model could power way more BEs than the new one.

You 22A ATX should be good for about 35 BEs (22A/0.6A = 36.6). Just make sure you don't draw more than 8A from a single 4-pin Molex and not more than 12A from a single string (though, again, depending on your ATX, you may get away with 16A per string). You will know if you draw too much, if some of the BEs will randomly stop hashing and light solid green.

Okay got this far and once again thanks. My next question is what is a safe load to run? If my PSU is rated at +5V 22A it should support 44 erupters. Now that is maxing it out at 110VA I know that cant be okay, so my question is at what capacity can I run this or any PSU? I was thinking of running 35 off it and two fans at 12V .85A so that is just about 80% of the +5V 22A rating. Also will that cause voltage drop because I am pulling more than 5A through an 18 gauge wire?

I haven't been keeping up on the specifics of this hub.  The last time I lurked in one of the related threads, they were still trying to figure out if the hub was drawing from the +5V or the +12V (with appropriate transformer/converter) leads on the 24-pin ATX connector.  Which one is it?

Also, do the Blue Furies fit on this hub without skipping ports?

Time to add an ASICMiner Block Eruper 49 port USB 2.0 hub to the list

Next add some some USB miners:

Orico Bokcore BC-U3H10-BK USB 3.0

Ordered it off Ebay. Got it in the mail the other day

Plug it in - Doesn't work.
Tried a few things (Pluged into a different computer, Reinstalled Drivers, Etc..)
Nothing worked. I was Pissed $60 down the drain.

Opened the Hub up, Took a look at the board.

This little guy - The solder broke off one of the terminals.

Soldered the one side back on and it worked like new.

I finally got around to taking some measurements to see how good / bad the 10 port Chinese hubs were.

I started with a generic 10 port hub that I disassembled, a 5V 5A power supply listed above and a PC power supply with a molex to barrel adapter.

Starting with the 5V5A delta, I measured 4.61 volts where the barrel jack joined the PCB and 4.53 volts across the capacitor at the far end with 9 erupters mining.  0.08 volt drop is about a half a watt.  This is not going to melt any power or ground traces.

Next I hooked up a Seasonic 80+ gold rated supply with a molex to barrel adapter.

I measured 4.64 volts where power entered and 4.54 volts across the capacitor at the far end with 9 erupters mining.  This too is not any problem.

Then I measured across the pins of the molex plug.  Here I saw 4.86 volts.  That's 0.22 volt drop between the molex and the PCB, most likely in the barrel plug.  This is more than I like so I agree with those who propose soldering directly to the PCB to eliminate the barrel plug/jack.  Finally I measured at the 24 pin ATX power connector and found 4.97 volts showing a 0.10 volt drop in the 18 AWG wire from the PSU to the molex jack.

I then removed the barrel jack from the PCB and the molex lead and soldered the wires directly to the PCB.  This gave me 4.92 volts at the PCB unloaded, 4.85 with 9 miners a mining and 4.75 at the far end.  This is much better in my opinion.

So, I don't think there is anything really wrong with the cheap Chinese 10 port hubs themselves as long as you are reasonably handy.  Removing the barrel plug and soldering a pair of 16AWG wires to the PCB should solve all your problems.

That's why I stick to the cheapo, readily available hubs.  So far, the cheapos are still working fine; I guess not loading them to the max (only at around 62%) helped.

Works for me-THANKS!!

I ordered it on 10-Sept and it was delivered on 18-Sept

It's the Asicminer made hub 

the 49USB + hub combo deal that will be offered will make it a great deal 

Once you, have it, please, write a short review here. Also, how much did it cost you, and where did you order it from?
I'll add all that to the OP table then.

49 port hubs are on route to me from hong kong, maybe friday/saturday
