[Solved] Block Erupters Stopped Working

[Useless1d1ot]

I know.  I love this 49 port hub.  But if I have to go though this every 2nd Tuesday of the month, I'm not going to be a happy camper.

I previously had multiple hubs; Rosewill, Anker, etc but all sometimes would have an erupter hang on old work or something when I go to manually switch solo mining a different coin. I noticed if I waited long enough all the erupters would complete their work and not get hung up. Sometimes this stilll doesn't seem to be the case, but regardless only ~38 erupters of 48 (where is #49...it went missing). Headaches...

Fixed. Thanks for the help everybody! PM me and I'll send you some UNO for the help!

And now I may have figured out the issue. It seems 3.6.6 is corrupting my drivers or something. It crashes whereas 3.4.3 is fine?

Edit: Fixed Again
I did a hard shutdown.
Unplugged all the usb miners and the hub.
I restarted the machine.
Scanned for Device Changes.
Plugged in hub.
Plugged in 1x miner.
Reinstalled driver via Zadig.
Tried mining. (confirmed works again)
Stopped mining.
Plugged in all the remaining miners.
started mining (success)


This is not...going....to be fun at all and why did I put pauses there?

Came home to smell of burning




Replaced the 40 amp fuse after I was able to get the melted one pried out with pliers. Works again, so I put a fan agled at the fuse...

reinstall the silab driver, then repeat the normal installation process.

cgminer doesn't use the silab driver

What driver do you use for block erupters and cgminer on osx?

Osx, like linux, need no drivers at all with cgminer.

Holy Crap!  My fuse was getting warm.  But I don't think it was quite that warm.

How many BE's did you have plugged in?

I had 47 and two fans in mine.  Then two BE's were reporting 1Ths and a bunch of HW errors so I dropped it down to 40 and all is stable.

Putting a fan on the fuse may keep it cool but it won't reduce the current flow through it.  Also you need to make sure the contacts are cleaned well so that you have as little resistance as possible in the connection.  I absolutely do not have a warm fuzzy feeling about these Hubs anymore.  I may drop mine below 40 after seeing your pic.

Thanks for sharing,
Sam

Hey OP,
Haven't heard back from you yet.  Is the hub up and running again or is it totally fried?

[helipotte]

I hardwired my hubs (aka no 40 amp fuse at all! ).  These things have fuses on every port and one for the controllers.  Also most ATX power supplies have built in overload protection anyway.  In case of shorts or overcurrent.

My hubs are maxed out.  One of them even has 10 overclocked erupters running at 448Mhs.
