Ok I have 3 blue fury's..

They where working fine but all of a sudden 2 have stopped working

Both of them have orange lights and are not recognised by windows.

I have tried rebooting and tried them in different ports but nothing.

I even removed the. Driver but nothing.

Any ideas?

Have you tried the reset button?

Hey Beastlymac,

Is it okay if I offer people repairs to their USB miners that have faulty LED lights and bad resistors?

https://bitcointalksearch.org/topic/dead-redfury-repair-service-in-los-angeles-ca-364290

Sure. Although i would recommend if someone has a faulty unit that is unmodified for them to contact us about getting a replacement. Once units have been modded we can't offer replacements.

thanks for the replies, its a usb3 hub:
http://www.ebay.ie/itm/131040267176?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
but i think others say usb3 is ok for them...
power on it says 5vdc which should be right for 2 sticks..?

do you recall which thread the list of good and bad hubs are listed, cant find it:/ think i need to make new purchase.
thanks!

That's confusing because USB 3 hubs are 12 volts I thought.

Would be the Amps that determine how many you can run.
all usb hubs put out 5 volts  the usb port, but they have different input power bricks.. if the hub has a 5 volt brick there is no dc to dc converter in it. if a HUB has a 12 volt brick there is a 12 volt to 5 volt dc to dc converter in it.   general rules of thumb a 12 volt brick when converted to 5 volts keeps 80 percent of the power.  so 12 volt  x 5 amp = 60 watts x 80 percent or  48 watts.   safe 24/7/365 run is at 80 percent so 80 percent time 48 = 38.4 watts to 3.84 watts for 1 of 10 ports.

a 5 volt hub is 5 volts x ? amps .. I have a few that are 4 amps so 5 x 4 = 20 watts  at  24/7/365 x 80 percent = 16 watts   so if this is for a 7 port hub it is a no go  as 16 /7 = 2.2 watts a port which is not enough.

I am assuimng the bricks run to their ratings.  most don't

never never never stick a 12 volt hub brick into a 5 volt  hub ..  you will fry the hub and the sticks/  been there  done that.

here is a 7 port hub with a 5 volt 4 amp brick  it runs 3 or 4 sticks:

before

here is a 10 port hub with a 12 volt 4 amp hub


 http://www.gearmo.com/shop/10-port-usb-3-hub-gm-3dh10/ 

 this runs around 6 sticks.   if you take this hubs brick and stick it in the 7 port hub from the same company you will burn up the 7 port hub.

I had hundreds of am sticks and around 20 -25 hubs   I learned one lesson don't mix hubs   make sure every one is a 5 volt power brick or a 12 volt power brick.. this way you can't burn the gear up
thanks a mil for the detailed reply! ill be sure to check this before buying a replacement Grin

Because I'm no electrician, I have to ask at that point :

Is it of any advantage (does it work in the 1st place) to replace i.e. a 5V Power Supply with i.e. a generic (switchable) one and give it 6V ?
Provided it has the Amps, that's basically overvolting the Hub a little bit. I do own some of those old "universal DC adapters" that let me go 1.5V/3V/6V/12V with a switch.
(the only reason I haven't tested it yet on 6V is that polarity is also a manual selection and the Symbology standard printed on the default USB Power Supply apparently changed sometime, didn't get smart out of it so far and need to carefully verify that; certainly don't want to mess that one up :p )

My idea is, that the USB ASICs then could have a bit more power available which (from my understanding) doesn't hurt them and should increase their hashrate towards their rated specs (mine run the typical ~2.1 Gh/s vs. the advertised "upto" 2.6 Gh/s, which I credit to the USB 2.0 Hub keeping its power output strictly to USB specs)

Workable idea or a good way to kill the Hub/ASICs ? I wouldn't mind "sacrificing" a Hub in the name of science *g* but don't want to bury a miner of course.

hi guys, i bought a usb hub for my 2 red fury miners and while running for a few mins they are declared sick then dead... but they are fine when i plug them back into regular usb slots and mine wout the hub. id rather use the hub as the miners block access to other ports. any hints anyone?
cant find similar posts on this here, sorry for repeat post if it was addressed already.
cheers
What sort of hub did you try?  You need to have a powered hub with sufficient current capacity for your miners.  You'd do better if you avoid connecting fans or other gadgets to ports close to your Red Furies.  It should be a USB 2 hub, not USB 3.  There is a thread somewhere on this site with a list of 'good' and 'bad' hubs for Block Erupters, which should probably apply also to RF's.  Check that you see the devices in Device Manager if you use Windows.  Make sure that they are detected with the correct driver assigned if you played with cgminer and bfgminer.  My BF/RF's are using a very cheap 10 port USB2 hub with an alternative plug pack that delivers 4A instead of the original.  The coexist with a bunch of other USB miners, some using bfgminer and some cgminer.

Cheers

its not true HW errors (bad nonce data), its just erraneous garbage the uC spits out while reading the buffer that contain the good nonces the ßfury found since last poll

buffer[0...15 or 16] is the good nonce data. i think it reads the whole buffer and sends it over usb

Thanks, so I'm basically looking good with my setup Smiley

Now I only wish I could find some more of these or similar devices for a reasonable price in Germany. It's literally insane what even small 330MH/s Block Erupters are selling for over here...

Got me three Blue Fury v2 miners rated @ 2.6Gh/s (don't bash me, I came from running several GPUs, so to me it's a major improvement Wink ).

Setup with cgminer latest version and a working USB 2.0 hub is running just fine, but what I get is this :


Not too far under par but clearly not quite as fast as expected.
Any typical n00b errors I could have made?

On the positive side, these things hardly get warm with just a light breeze flowing over them.

PS.

The amount of HW errors seems quite high... Any way to work on getting this figure lower ?
