This USB hub looks to be 5v 4amp with 10 ports.  Would you expect this hub to work fine?

Excellent troubleshooting.  I did not think to directly connect one or two of the gridseeds to a usb 2.0 right on the mother board.  I will attempt this tonight.

The lights look good.  Green flashes on all ten units in 1 second increments, which seems to be right according to info I collected a few days back:

What do the lights mean?

GREEN flashing LED means - 5V is ON / drive electronics are powered up.
GREEN LED is ON for 1 second, OFF for 1 second.

RED flashing LED - ON 3 seconds / OFF 3 seconds:
Miner Is Hashing / Processing Data.

RED flashing LED - ON 60 to 70 seconds - OFF 60 to 70 seconds
Miner is Not Hashing / Processing Data.

If Fan is OFF and RED LED IS STUCK ON or OFF i.e. not flashing:
12V is OFF - 5V is ON.

FAN is ON but no GREEN OR RED LED's are flashing ON or OFF:
12V ON - 5V OFF.

When first powering the miner on, the best sequence I have found is:

First, turn 12V Power ON
Second, turn 5V USB Power ON
This will enable self test to occur in correct sequence. (I'm guessing)
If you do not use correct power up sequence, various hash / no hash / no shares reported type problems may occur. (I'm guessing here too)

 
A few seconds after 5V USB Power is turned on, the GREEN LED's will start
to flash ON/OFF as written above.
After 12V power is turned ON, in about 60 to 70 seconds,
the RED LED's will start to sequence ON/OFF as written above.

3.0 usb hub is always NO for gridseeds.
Use 2.0 usb hub or just directly connect 1 or 2 miners to computer & check.
Is the led lights green & red blinking in gridseeds?

I have had ten gridseeds for about a week now and have a unique problem that I think will only be solved by the smart people in this forum.  The gridseeds look like they are hashing according to bfgminer, but the devices are not going “online”.  Of course there is no issue with my system being on the internet itself as other devices are hashing fine and no issues surfing the web. I have also attempted to use different pools to ensure it is not a pool specific or stratum issue.

The ten gridseeds you see in the picture are on virtual COM ports 1-10.  The USB hub is 3.0 but connected to 2.0 port on the Z87 motherboard.  I do not believe there are any power issues or driver issues because the units are connected and hashing locally.  They are just not going "online" to connect to the pools.  I am going bonkers on this issue and would be more than happy to send a Doge or BTC tip to whomever can solve this issue!

That's just your opinion, not everyone mines to sell for BTC. Maybe some people like to mine different Scrypt coins.
But yes for some people it's better to buy low and sell high.

But I rather buy a miner that I know will have some resell value left when I'm done mining, than try to out smart the market.
Remember that the ASICMiner USB miners still sell on eBay.

Do you even understand what ROI means?
If the price rises to 1k again.

The one who bought Gridseed Miners gains a few $.
But the one who bought with the same money bitcoins instead of gridseed miners will profit even more.

That's my point. Buying Mining equipment NOW is just plain stupid. The Miners are too expensive compared to difficulty and difficulty increasing rate.

What if the price of BTC suddenly increases to 1k again? Ever thought of that?

Why do you all bother to buy these miners?
They won't reach ROI ever...

240$ investment per Miner.
330 KH/s

Even with only 2% difficulty increasement (unrealistic, realistic is about 10-15%, calculate allways the worst case), you won't reach ROI.
Better buy the coins instead of giving away free USD/Coins to all hardware sellers.

Has anyone in the states been able to deal directly with diginforce.com? I have been trying to register with their site but no luck so far. I am considering driving 45 minutes to the nearest 4 year university to see if I can find someone who will help me translate/walk me through placing an order with them.

indeed a hero member

How do you come in contact with gridseed? Or with diginforce? Cant find it on these chinese websites.
Thanks

Yeah, no response so far 

From what I have read, its not possible yet.

I would guess when they get ready to put out gen2 chips, they'll pump out their last gen1's for customers.. maybe?

Have you tried contacting Gridseed directly?

Does anyone know where I can get just the GC3355 chips?

this reminds me folks replacing their gpus with asicminer usbs

I can get you in touch with a shipping agent in china if you need to. Just throw me a PM

Dear forum members

I am thinking about buying 500 gridseed from gridseed.com in china. I heard from them that you have to arrange the transport yourself. I wouldn't know how to do this, has anyone has experience with this? I live in the netherlands

Thanks


and this is a company in Germany that gave me a pm since I was interested.
This is his website :

Hi all.
Anyone knows, where I can buy the Gridseed items in Germany (I only know this shop: https://www.msp-home.de).
Thanks
