Topic: [ANN] Bi•Fury | 5 GH/s USB Miner [IN STOCK!] {SALE !} - page 18. (Read 304997 times)

Damn, just saw it. Same problem here :-(
So beside the "old problems" (not working properly in combination with other miners) I now also have a reduced hashrate. Bad deal...
Can someone upload the old firmware, please? Unfortunately I did not save mine...

Everyone else experienced performance issues after upgrade?
I had about 4.8gh/s before, now I have bellow 2gh/s 

In the latest firmware, the red LED flashes every time the card has found a share that meets the difficulty.

That's good news.
Is there a way to check what version currently is installed on device? Of course I can always compare firmware.bin files

Still I'm curios about red flashing LED what dose that mean? Asking because I have several devices and only one have flashing that LED, on other hand, all devices have accepted shares as reported by cgminer. As the color of LED is red I start to worry a bit, is it some error, warning or what

Sorry for delay!
I just add newest firmware and upgrade instruction.

Please check it on store.bitcoin.org.pl/support

And for clearance, we have a middle firmware since we start selling and we are testing our equipment before shipping, especially to catch all kind of buggy devices 

Yes, a USB CDC ACM device, so would be /dev/ttyACMn form.

Felipeo said it would be on http://store.bitcoin.org.pl/support a few weeks ago, but I can't seem to find it either

Good point, I'll check that. Maybe you know what kind of device is it? tty?

Could you please point me where to look for more info about update? Somehow couldn't find anything usable, perhaps wrong search parameters 

No, this looks more like a broken USB hub or insufficient power...

The shipped firmware for some (most?) of the bi*fury is buggy, and an updated firmware is needed to get them to mine correctly.

Hello,

I have got several BiFury miners, it looks like it has very little or almost no support at all.
That's why I'd be happy if someone could help me a little bit.

First o fall is there some way how to get it running under Linux? To be more specific Debian 7.2.
When I connect device to system in kernel log I see:
[1704559.597506] usb 2-2.1: new full-speed USB device number 9 using uhci_hcd
[1704559.733273] usb 2-2.1: device descriptor read/64, error -71
[1704559.860650] hub 2-2:1.0: unable to enumerate USB device on port 1

It looks like I need some driver is missing (module).

Few more questions:
Under windows I have running devices with cgminer, but no device is running with promissed 5+gh/s I have about 4.6-4.7gh/s. What can cause this problem?
What is normal running temperature and what is maximum acceptable temperature for this device?
What dose red blinking led mean?

In bgfminer readme is written:
It looks quite clear, but only problem is where I can get mentioned file firmware.bin? And why should I change it?

Maybe there is some way to overclock device, to get higher hash rate?

I'll be happy if someone could help or explain me any of questions written Wink
Thank you!
Cheers,
Lauris

Thanks it is working well now useing USB 2 and a powered hub on cgminer Winusb at 5GH/s

thanks

Feel free to use this one:
http://cex.io (Feel free to use my referal link: https://cex.io/r/0/FlensGold/0/)
Current price is 0.06615BTC/GHS

could you please provide a link to the orderpage ??

on cex.io now it's 0.065BTC/GHS and it's aviable instantaneously

> $110.00 per GH/s is not really compelling at this point. Hashfast is a $5.625/GH/s

Any chances the prices of these will go down, currently with the rate of difficulty increase there is no way it will pay for itself in bitcoins.

10 of these would generate 0.0413BTC/Day at current difficulty.
i would need a price of 0.1BTC per device to break even in a timely and worthwile manner.

adjust you price for difficulty and exchange rate.

USB3 slots and these devices on cgminer are problematic. Try in USB2 slots if you have them available.

Tell me how and I will
I do get this

Can you post a backtrace?

OK I have a problem

OP Windows 7

BFGMiner 3.7.0

BiFURY running by itself on a usb 3 hub with a fan

I can get it running and the temp is at about 48C
But after a few miner BFGMiner crashes

Can anyone help

I have also tried the most up to date CGMiner. Have used zigzag and with the bare firmware
It is never seen

Do your prices even scale with btc value?

 500$ for 5ghs usb? no thanks.
