Can i use the new firmware and to the  4gh/s version of the usb?

Yes, 4gh/s version is the same device. There is only difference in final chip performance and hashrate(not all chips are the same).

Hey everybody.

I've read that this miner is optimized for USB 3.0 OR for use at an active USB 2.0 Hub.

So is that right? Or will i lose GH/s if i connect it to an USB 2.0 Hub with additional power supply ?!

It's a USB 2.0 miner, but with higher power requirements, so a 2.0 Hub + extra power is just what you need.

Happy with your c-scape product ? Consider a tip: 16X2FWVRz6UzPWsu4WjKBMJatR7UvyKzcy

Don't think so, prices for all USB miners are presently all hovering in orbit and are highly uncompetitive. Wait for them to adjust but don't expect too much. Like everything in stock on the market, right now every piece of ASIC hardware seems only meant to be profitable for the hardware seller, not the customer by a very far margin.
It almost feels like they don't want too many customers at this time for some reason (?).

Although I had the cash and the basic incentive, I wouldn't ever consider buying at these prices.
I mean it's their business and I'm not to complain - but if they keep them that high for a few more weeks, they'll be 'competing' with cex.io prices Tongue quite an achievement...

I racked up on Red Furies and Antminers at really good prices. Want one of these because of the hash per watt is pretty awesome. Ah well, will wait. I'd rather invest in Dualminers but those are also too $$.

Why do people buy multiple of the same product?  Does it become ineffective quickly?

The higher your total hashrate the faster you mine and get paid.
So if you stack 10 of these you have 50gh/s which will get you more back faster than just one.
The same goes for any type of miner.  More, bigger, faster the better.

The reverse is also true. If you purchased badly and spent more on the device than you'll ever earn back effectively making a loss, then buying 10 of them means you make 10x the loss.

Thanks

USB miners are easy to setup for newbies.

And cryptocoins are not mainstream yet so expect a lot of newbies coming on board everyday.

Hello guys,

I need your help. Three days ago I have bought Bi fury 5GH, but I have some issues. My computer (win7) cant recognize it in USB 3.0, it can recognize as Unknown Device. I tried install many recommened drivers but nothing helped. My computer can easly recognize Bi fury in USB 2. Do you think that another FIRMWARE is needed?

Thank you for your help.

I am using usb extender, but i tried it in usb2 and usb 3 too, so i dont know if it is a problem using it through extender.
I have Artic breeze fan.
I reinstal driver with zadig
It doesnt matter if i plug it after or before.... but in beginning it didnt say that there is some error just it has 0 hash speed
There are some photos...
