I think all 3.0 hubs Support 2.0 ... but most devices like Keyboards, mice and the Erupters are 1.1, which isn't supported by most hubs anymore

The raspberry pi is not able to utilize USB 3.0 hubs

sex.com was sold in 2010 for 13,000,000$

Probably there will never be an ASIC being able to do both ... because then, it would not really be Application Specific (that is what the A and S are standing for), it would more be like an FPGA.

Bitcoinminers are mostly already unprofitable if you don't have them yet ... Any device you buy will most likely not make any ROI.

Scrypt is still doable by GPUs, no FPGAs or ASICs which are soon to be released.

So I got everything working at the moment ... WiFi on the Pi, 10 Erupter USBs on 3 DLink Hubs ... everything works fine for some hours after which the LEDs on all Sticks are going into a constant green light, and I cannot ping or access the raspberry any more ... so kind of a freeze ...

Anyone has an idea what may be causing this? And how to prevent it?

As a workaround, I was thinking to have a script running, which is rebooting the pi every hour or two, but have to clue how to setup this in linux ... my last use of linux is like ten or more years ago

Any help would be appreciated.

Anyone got an idea what the problem is? Using a 5V/2A 4 port noname hub. The same problem exists for 2-4 USB Sticks ... Only one will hash in a good way ... Is it the power supply or could it be any other issue? (Getting some Dlink Hubs in the near future )

Theoretisch kein Problem ... ABER ... mehr Strom = mehr Wärme ... Wenn das nen "billig" Hub ist, kann es sein, dass der es nicht mag, wenn mehr als 2-3A da durchlaufen ... Gibts keine Infos auf dem Hub, was der als Eingangsspannung/Eingangstrom abkann?


edit:

Hier gibts ne Liste von Hubs ... Alle 2.0er sollten auf dem Pi laufen

Ja USB 3.0 is abwärtskompatibel ... aber trotzdem scheint der RaspPi keine 3.0er Hubs zu finden ... Habe es selbst mit meinem Anker 10er Hub ausprobiert, auch einen USB 2.0 Hub "dazwischen" zu hängen hat nicht geholfen.

Naja irgendwann wird der Reward für einen Block ja auch extrem gering (<1BTC) ... Da können die Gebühren schon einen größeren Teil ausmachen

Der Anker 10er USB 3.0 Hub liefert z.b. mehr ... Generell liefern USB 3.0 Hubs meistens mehr, weil hier jeder Port auch mehr ziehen darf. Allerdings funktionieren diese Hubs leider nicht mit einem Raspberry Pi

nice

They are ASICs (Application specific integrated circuit), which can be used to mine all SHA256 coins (Bitcoin, PPCoin, TerraCoin etc.) ... The will yield about 330-335MH/s like a middle class GPU

But then, it would still have been better to buy BTC with the money

In Germany (where I live) you have to pay VAT (19%) + customs fee (0-5% depending on the type of items) ...

There probably is information available for the USA on some website of the gov I guess

You will probably have to pay taxes like VAT when importing goods from abroad. There is probably a treshold under which you don't have to pay, but this is usually ~500$ . You will have to declare it and go to the customs line (something to declare).

When you buy sth inside a land and are leaving that land, you usually can get back their VAT (using some forms at the airport or the shop or somewhere), so if the VAT in the USA is lower than in the original country, you more or less don't loose money.

Also reverted to 3.1.1. and works superb ... several days without restarting ... error rate <1%, everything fine

There is one provided, but it is sooo extremely bad ... And no one stops you from installing a better one (If you want GBit Ethernet and 300Mbit WiFi you have no choise for example)

Because they do it themself ... probably because less people would trust someone their bitcoins who are MTGO traders based on their name

This cannot work ... there are no 2k ONC ... there will ever only be 1 ONC ...

so are you looking for 2k nONC, or µONC or what?
