Title: Anker 10 port Aluminum Hub - Not Working
Post by: xzempt on August 27, 2013, 05:58:09 PM
One of my Anker 10 Port Hubs quit working after I restarted a computer.   It will work with 1 USB miner in it, but not more than one.... 

I've tried other power supplies that are known to be good and work fine on other hubs...  same issue...

any ideas? :-\

Do they light up when plugged in and just not recognized?

I burned the wall wart out on my hub, couldn't find another one, so rigged up a molex -> bullet connector from the main PS and that works a treat (with lots of headroom on the AMP side to boot ;) )

Sounds like the power brick died/weakened. My non anker generic cheap hub would only run two at a time without the external power, then I spent like $5 on a package of molex (male) connectors and the male pins, snipped the plug off the wall wart, connected it to the pins, fed them to the +5 and ground of one of the 'extra' connectors coming from the PS, plugged it in and now all six are humming away just fine (with a fan off the same source)

When I get home.. fairly simple to do though..

Though I did goof up and connected the - to the 12v ground, but it's all a common ground so it don't matter.

How many Anker hubs do you have chained together, in what type of configuration?

The problems you're describing sound exactly like when I tried chaining too many ANker hubs together.

I solved this by running multiple chains of only two hubs in length directly to the motherboard. So.. for 10 hubs, I had to do 5 chains of 2 hubs each (luckily I had 7+ USB ports on my mobo).

Just remember the molex connector has both +12 and +5 on it, the colored wires at each side are the + side while the middle two are ground (-)
Typically the red conductor is +5 and the yellow is +12. You'll want the male versions of the pins and the connector.

The wall wart or hub itself should identify the +/- config of the plug for the hub.

I used solder in addition to the crimp on the pin as the wire for the hub's power supply wasn't #18 awg.

Good luck.
