hmmmm
Will buy from this site.
Did you not just read the recent posts?!

I didn't read this thread before I made two purchases from this site and now I've become concerned. Purchased Saints Row IV and Minecraft so I'm hoping they come through...

I checked on the Blockchain and the funds for both of my purchases and what I'm guessing are other recent users purchases have been moved around a couple times, ended up at this wallet so far: https://blockchain.info/address/18WrPcHaWCn3RwmGPfJKqxsM3egzC95tGs

What's the deal? I made these purchases as last I checked months ago this site was legit.. Anyways, hoping to get what I paid for.

Re: Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury? A List.

In regards to the 4 ports failing, I noticed the same issue with 2 of my 13 port hubs. I have found that it's actually a surface mount fuse that is the problem.

As a temporary solution see this image for the mod I did to both of mine to get them to work:

https://dl.dropboxusercontent.com/u/54696378/Keepers/USBPCBMod.jpg

After a continuity test I found that one fuse did not reset, after bridging the connection the ports came back to life.

As you can see by the traces on the PCB that one fuse links up to 4 ports where as the other 3 fuses are linked to 3 ports each.

We are in the process of getting the issue resolved though for the time being this mod has allowed my BEs to run for days without any further issues.

For good measure here's some pictures of my setup using the 13 port hubs provided by WTCR: http://imgur.com/a/ddCPb

Nice solution. I think I'll sink mine into the case as well and place a speed-reduced 92mm fan over them.
Just ordered 2 more of those hubs.

Are you located in Canada or the US? Just wondering how you're able to justify the shipping (which actually costs more than the item itself.)

I work at WTCR ;].

Let me know how many your looking for and I can probably work out a deal!

As mentioned in my previous post, the Satechi 10 port USB 3.0 hub does not work with the USB BE's, it only works well as a base hub, the main page should be updated as such.

The 7-port Manhattan USB hub (https://www.adafruit.com/products/961) mentioned in the Adafruit tutorial (http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/) only works with ~4 Block Erupters.

I'm still looking for a good hub for 6+ Block Erupters that works with Raspberry Pi (i.e. not USB 3.0)

The D-Link DUB-H7 definitely works with 6 units on the Pi, there's a guy who was running 30+ erupters with the D-Link hubs, he posted it on Reddit with a cool 3D printed enclosure.

Anyways as a reference I also have a D-Link hub and it's running off my Pi without issues.

Hello all, I already posted this in the newbie section though to get the proper exposure I'm posting it here..

A co-worker and myself recently picked up two of the Satechi 10 port hubs to test out some of the ASICMiner USB Block Erupters and seem to be having nothing but issues so I was wondering if anyone else out there has used them with success?

Basically the situation goes like so:

With one block erupter it will run for a little over an hour and then I'll get the solid green light and CGMiner spams Comms Error.

With two or more block erupters they run for maybe 30 seconds if that and then I get solid green lights on random units, sometimes they will come back online and then just go back offline, same deal with CGMiner spamming Comms Error.

I then took my D-Link DUB-H7 hub and connected it to the Satechi 10 port with one erupter in the D-Link hub and now it has been running for days without issue.

I have contacted Satechi and they pretty much have said they have never heard of ASICMiner products and assume they will not work on their hub...

Also as a frame of reference, I have tested this on Windows 7, Windows 8 and even my Raspberry Pi running MinePeon, all of them run into the exact same issue.

I had assumed that being a 10 port hub with a 5V 5A power supply it would be perfect for a USB mining rig though it looks like at this point I was wrong.

Anyways, just wanted to let others know as I haven't seen anyone else testing these hubs.
