the revision requires USB 3.0 port? is that the deal with K1 PCB re-design?

BkkCoins gives an answer here:

It's a little vague, but seems to indicate that USB 3.0 hubs are preferred to be on the safe side, power-wise.

Far from vague. Pretty much details what concerns you need to have when sourcing 2.0 vs 3.0 USB hubs given the limits imposed typically by 2.0 specs.

Added to the list. What are the specs for its AC adapter? Couldn't find them anywhere.

With vague, I meant if K1 would stay within USB 2.0 specs of 0.5A or if it would overdraw.

Followup: Cambrionix 49 port has no problem running 48 of these from a Sparkle 400w power supply.  I'm sure it will run 49, but ive got one mangled broken port.

Confirmed working on win7 and Ubuntu 12.0.4.  Probably compatible with beaglebone, but I had some cgminer issues in testing.

I've started on a table over the hubs that were mentioned or look promising. See OP. If anyone had successful experience with any other hubs, please mention them here.

I'm having good results with the Cambrionix A6 49 port 2.0 Hub on Windows7.  Will update once I've tested it on BeagleBone Black.

It's waaaaaay too expensive to buy new, but I scored a used one for $200.

Currently running perfect with 33 Erupters, 16 more on the way.  Hoping my Sparkle Power Supply can drive all 49!
$200 for it is a steal!!!!  i'm getting quotes of over $1000.  ordered me one to help me with Eligius branding and testing of USB Miners sold on their pool's website. should arrive tomorrow

$200 was the right place right time.  Just learned that my unit has one bad port.  I think someone tried to use an actual key in the USB port.  I'm thinking I can fix it easily, but don't want to stop mining!

I think we are all in envy of this hub!   Do you mind posting pic of it with miners?   Would love to see this setup!

Yes that be a nice question to ask him.

I'd like to add that I didn't need a USB hub for a single stick in my Pi... seeing as there was only one of them.

I was waiting to fill it before posting any shots.  Running 49 units at 16.3 Gh/s on a Sparkle ATX-400PN.   Port 43 is damaged.  Sad

update: tech republic 7 port burns up the power adapters with 6 filled, going back down to 5 each. They are sending replacements power adapters for free though so not a huge loss. I have one hooked up to psu power with all 7 filled and works so far. I will report back in a couple weeks when I'm fairly certain its ok, and before converting the others to molex connectors

Good that at least your miners didn't burn. I've update the table with 5 as the upper limit.

Added your find to the table, right after Anker. I used Amazon price with a footnote, pointing to your review. By the way, Amazon states that the hub has 5A adapter.

Yeah sorry, they are 5 amps, not 4 amps. I misread your initial post thinking you said volts, not amps.



And USB miners working.

Update 7/21/13: The Antec 550 PSU this came with has died.  I went and got an Corsair 750 and got all 49 miners going again.  Not a pleasant experience.  this hub is difficult to work with in Windows.

DS-IP-SC-49 Draft Review:

http://www.cambrionix.com/cambrionix_products/large-capacity-charge-and-sync-station-professional-series-a6/
http://www.ipadcarts.com/solutions/DS-IP-SC-49.htm

I have received 1 unit of DS-IP-SC-49 to test and review.  I have not gotten it for free, I paid for it, so that there's no bias.  I also needed something like this for branding Eligius branded ASICMiner USB Eruptors.

I tested it with a 3 yr old toshiba laptop running Win 7 64-bit running "bfgminer.exe -S all"

Packaging: --- Simple and functional  box padded with foam, well designed.

Power: --- This is a bit of a headache.... It came with a Gold rated Antec 550W PSU, which died on me 12 hours into operation.  When I would try to get it going again, the fan would jolt, immediatly stop and a clicking noise can be heard and nothing... I ran out to a local Fry's and picked up a Gold rated Corsair 750W (too much but they had a good deal on it), connected the ATX24 5V 28A and was back in business.   More on the power issue: xjack pointed out to me that this 5V 28A ATX connector delivers 140W (is my math right?), however 49 miners, use 2.5*49= 122.5W, so 122.5/140= 87.5% load...  This is the load on the mobo ATX connector, not the whole PSU... I think this is pushing it and the manufacturer should consider utilizing one more power connector from the same PSU (it is modular afterall) to deliver more power so that there isn't such a high load on the single ATX power connector.  maybe i'm wrong in this assessment, but 87.5% load is beginning to push things.

Installation: --- It is very difficult to operate this hub with all 49 USBs populated with ASICMiner Block Eruptors.  This 49 port hub actually consists of 7 hubs linked together from the point of the device manager.  If you plugin this 49 port to your computer USB interface and all 49 ports are populated with miners, only 14 are recognized and the rest don't even power on.  I'm not sure what happens but the driver installation when detecting this hub with all ports populated does not work well at all on Windows.  The solution, or the proper way to bring online is as follows:
-boot up
-connect the empty 49 port hub
-insert miners one at a time, till you see a message that the device is ready
-repeat above line 49 times
-start mining
in case you need to restart the computer, you need to unplug all Eruptors and repeat above steps.
if you reboot with everything connected, most of the miners will not be recognized and you will need to "uninstall" each of the 7 generic USB hubs listed in Device manager.  only after that, your will need to repeat above steps.  I've battled with these steps for a good 5 hours.. it's a pain, but if you follow these steps, it works just fine.

Design: --- physically it's excellent!  I think the manufacturer chose the ATX power because it makes the power on button easy to operate.  But another power connector should have been added in addition to single ATX.  I had an issue with 1 USB port which due to me pulling out and re-inserting the miners became too lose and I had to bend the edges inward to create a tighter fit, otherwise the miner was wobbly and didn't have a good connection to power on.  but I don't think this is a countable negative...

Pros: real estate compactness/ dense, less wires, power strips etc... Fantastic spacing between ports for thermal characteristics (heat dissipation).  access to plug and unplug USB miners by having good access to do so without touching or bumping other USB miners while they operate. Rock-solid design, not flaky, can take abuse, wear and tear.  ports are pretty sturdy, do not sink or bend.

Cons: Price!!  $23 per port.  the system I tested has an issue if you plug in all 49 usbs and connect the unit to the computer.  I don't expect this to be an issue in Linux however.  Maybe it's a Windows thing with that many devices.  I believe it has to do more with the driver for the miners and not the 49 port hub itself.

Conclusion:  A very good hub to run 49 miners in a small amount of space (but it is not for a novice and I mean no disrespect by this!)  It would really be good to test it while mining on Linux, but I'm not  going to do it.  The only thing I use this on Linux for is to brand the Eruptors for Eligius mining pool.  I don't mine on Linux.

To Do:  Contact manufacturer, explain bitcoin market, suggest higher production to reduce price and release in bitcoin market.  Request a 64 port (8x8) USB 3.0 hub to be made.  Reduce cost by dropping PSU, you all have a box of them lying around anyways...

I don't have a very favorable opinion (access: spacing and resulting thermal density) about the new Anker 9 port hub and the Juiced 10 port hub as they compare to the prior Anker 10 port physically:

Juiced and new Anker are much denser than original 10 port Anker and leave very little space between ports.

So you might want to put a little more air movement and you need to be extra careful unplugging the USB miners, otherwise you will physically damage them and warranty is voided.
the charge port on the Anker is for charging only, there's no communication on it
