thanks for the CP210 manufacturing link Dunkelheit667 !

thank you

thanks all. I want to utilize all 49 ports, the new PSU is an Orion , came out of old tower server. 550W PSU with 36a +5v rail(same specs as the Hiper I blew up). assuming .6a X 49 asicminer sticks, we get 29.4a. throw 35a fuse in and I am good?

currently have 20 sticks on 15a fuse, running fine.

ok sorry to chime in here with some skepticism, but the miner in the pic just looks like and ASICMINER with new heatsinks put on. sounds like someone is trying to recoup BTC from previously purchased ASICMINERS. with next gen miners out now, usb miners are never going to generate ROI.

ROLF!

So, given my recent power surge/ strange melted fuse issue, who wants to speculate on this:

We had an ice storm that caused power outage. I was away, returned home to find all PC's off. Rebooted and started seeing the strange issues with my hub miners. Found the melted fuse, not blown. Cleaned it up, replaced fuse and also replaced the PSU to the hub. I also found some brown discoloration on 4 of the hub's ATX power connect pins. (assume the 5v rail and ground pins)

Previous PSU was nearly new Hiper PSU 36a +5v rail(I posted about this one before, had wrong mobo power connect for a build I had planned way back when, and was sitting in my closet new, unused).

Given the above, did the fuse just melt over time, or did the power outage blow the whole works?

The big question is this: Should I lower the amperage on the fuse in the hub? would that provide better protection? say 30a or 35a? A 25a fuse would be too small I think, just barely enough for 50 miners with no wiggle room. 30a would do up to 60 miners, so the 49 max  miners on the hub would be well protected.

hahaha, went away for the weekend before I posted this.....

Tried to reseat the fuse and power connectors on the hub and found the 40A fuse all melted and burned up. Apparently, there was a power outage while we were away.


To this unit's credit, I scrapped a bunch of charred plastic out of the fuse housing, replaced the fuse and it is now hashing away again with a new, beefier PSU (36A +5V rail) the unit I bought was the ASICMINER hub. I was surprised it still worked after seeing all the melted plastic from the fuse. Fuse did not trip, it just melted all over.

I need the software as well. Win7 64 bit. I was able to remove all the com ports with the link provided, show hidden devices trick.- Thanks wpt1wpt1 !

what is the cp210 manufacturer software? I have the vcp driver package is it in there?
I have found that the 'bad' BE's show up as silicon labs cp2102 UART Bridge controller in my devices.

I got one of those A*******r 49 port USB hubs a few weeks ago from one of their franchisees ( or however they figure out who can sell them) and it ran good, 2 dead ports to start. Now I have 17 bad ports. anyone else having trouble with them?
The bad ports power up BE's OK, but cannot mine or load drivers. I am using windows 7 64 bit, which may have something to do with it. But they seam pretty flimsy for the price that I paid.

Ok ay I see whats up there, I think, I accidentally had 1 of my workers on PPS that would account for it. Yes.  200,000 shares PPS this difficult. Last difficulty, I only had 22 shares PPS. "check the stupid stuff first"

yes, I have something back-asswards here, trying to figure it out. no offense intended. host computer specs should not have much to do with it? switched in an old amd laptop to host the BE's and a BFL jalapeno.

my stats look apporx. correct 2 workers 26GH/s total. >1% stales,both workers connected. just 1/2 the shares per shift.. weird. have to see what 24hrs.  does for earnings I guess see how it all washes out

BTW I like the new look, easier to see stats than switching pages;

I have been reworking my set up, since I fired up the 49 port hub, removed 1,000+ watts of power and moved my controller to a laptop. All my hashes are now from 2 machines. But when I first fired it up, I was getting 11K shares /shift. dropped down to 5,000. seams weird. just set my workers back down to diff 2, I assume the pool's vardif will kick them up a notch or 2?

here's a few shifts ago with all my hash on btcguild:

shifts 11640- 11648 roughly 11,000 shares per shift.

shifts since then have been 1/2 that. I admit I have not been 100% on BTCguild, but have been 100% since 11766 and only 5,000 per shift.
paranoid from 50BTC's 'evilpool' have I been compromised and don't know it?

my shares per shift seam off? I just increased difficulty on my workers could that do it?
isn't difficulty a factor of shares per shift? like dif 2 = 2 shares, 4= 4 shares ect...?
I was getting 11K shares per shift, now only 5K?

thanks, I got it working. It was the serial driver for the BFL.

whats that monster in the background? looks like 70 BE's? 

curious about some of the history; Answer if, or as you will any of the following:

would you comment on how much of the pool's hash rate is your own personal miners? How does BTCGuild's position as one of the top pools affect attacks? Are you confident the major pools out there are relatively secure (Re: 50BTC's recent tragedy)?

right around the 51% issue BTCGuild was facing, when the Avalon ASICS first appeared,  I noticed there was a user ASICMiner on your pool. then shortly after the ASICminer pool started showing up on the block origin rankings. was there any connection between ASICminer and BTCGuild? Were you involved in helping them set up their pool? Or was that 2 separate entities?

 

So how many for this deal? 127 per host, 5 hosts?  635 BE's?
1 - renesaince 3.0
4 openHCD hosts?

So, should I be using a 30a fuse to protect my PSU if it only has 32A on the 5V rail?

in theory 127 usb devices

No problem eleuthria - its good to know the fuse ratings. hehe I blew a 15 amp auto fuse earlier today

but I have 29 BE's running one now, will pick up a 30 until my fuse arrives.
