It's an OK hub, but I never got it to work reliably beyond 6 actual U1/U2 miners. I tried all different combinations, and it had 12V coming from an old AT power supply. It's a dandy5-6 port with wide spacing. If you are expecting to actually support 10 sticks, I predict you will be disappointed. Maybe it could be improved with some internal "surgery". I didn't try that. It does take in 12V, so there is obvious a 12V-to-5V step down converter.

This one looks like a company took the Orico I just linked and did a bit of work on beefing it up:
http://www.amazon.com/dp/B00JEVRXQA

Maybe I'll go for this one instead. I only have 4 compacs, so I think it's adequate for those OC'd a little, plus a fan.

The 2nd one you quoted, might be better. However, the marketing numbers still don't quite add up:

- 12V/4A power supply = 48W
- 5V/1A per USB port as described = 5W/port

It's still a bit short for 10 ports, but closer than 36W (i.e. 12V/3A).

Now I just need to find decent 4 port USB 2 powered hub. Unfortunately everything on the ORICO is USB 3 now. I've heard that USB 3 is problematic with RPi's.

If anyone can recommend a decent inexpensive 4 port USB 2 powered hub that has been known to work with the Pi, that would be great.

Here's a 10 port Orico usb 2.0 hub: http://www.amazon.com/ORICO-P10-U2-External-Desktop-Adapter/dp/B00EH44AA6/

I'm thinking of grabbing one to mess around with.

Updated the shipping queue. I got a few small orders in over the last few days, which are all going out. The first big US-domestic reseller shipment is going out, and the second is ready but waiting for a label. After that I have 134 sticks in six large-queue orders to send out. I'm going to try to have all of them out by next Friday.

Pretty soon I'll be out of parts and have to scrounge up for another batch. We brought in enough stuff to make 500 sticks. I was hoping they'd sell faster (and orders would get filled faster) so we'd already be buying the second half parts but it'll work out.

Thank you sidehack I got my production unit to play with. It is a beautiful little stick, and has worked great so far. I am running a RPI with raspbian and it is working well on it.

The only thing I would warn before jumping into hub with RPI is reading compatibility. In theory all usb 2 should work. But I found this not to be the case and it was a pain to get one working. I had to do a few mod's before I finally got it working. If you get one that has been tested already and order that hub your life will be much easier.

I've had really good luck with the ORICO 10 port hub. I've got several and have used them with RPis with no issue.

3 from all I read is worse then 2 on compatibility with RPI. I know what you mean those ORICO/Anker hubs were solid hubs I sold all mine though in the block erupter days.

But if you can get one verified to work it is will be very simple with RPI and install. I had no problem on software was all hardware with hub. So that is not any fault off Gekko Science. All RPI issues.

I've already got a couple of sticks. They're working great with Minera and an RPi

But now I'm thinking about building a standalone bitcoin lottery box as a christmas gift.

I think I could do this with one sick, a USB Y splitter (for overclocking if interesting), a bare RPi board, a USB powered case fan, a 4 port powered USB 2 hub, and a plastic case to house it all.

Since the Pi has a couple of USB ports, I could use one of them for a WiFi dongle instead of Ethernet. That way the box could be put anywhere in the house that has power. Of course it would still need an Ethernet jack for initial configuration.

The USB 2 hub would have to be decent enough to power the Pi, stick, fan, (and maybe a WiFi dongle) 24/7 inside an enclosure without falling over.

The challenge would be to get the entire package compact enough, be well ventilated, and look nice. A clear case would be cool because you could see the components. But that means everything has to be neat and tidy inside (not my strong suit). Maybe a black case with an LED illuminated case fan so that you can see that it's on.

I'm still mulling this over. If anyone has suggestions, let me know.

The USB 2.0 models of our hubs are not designed to run at 100% for
extended periods of time, their voltage regulators will fail early due to thermal load
problems.

Pfft. Weak sauce.

Kinda my thoughts, too, especially given how beefy they appear to be and how expensive they are. Oh well, live and learn.

What kind of power do those hubs put out on the ports? Looked at those before, but never could find the power output, so forgot about them.

I've sent them an inquiry, will share when I hear back.

So they replied back to me and said "Maximum is 500ma" which I already knew is the max rating for USB 2.0, but I don't think it answers our question.

A more complete answer from the CoolGear USB folk:

Quote

The 2.0 model hubs are not designed to operate near their limits on all ports for extended
time periods (thermal issues), whereas the 3.0 models can handle this fine. I've run some
old block erupters on several models of our hubs for a few hours without issue, but I
admit it was an educational exercise and I didn't try to overclock them or run for
days/weeks.

The USB 2.0 models of our hubs are not designed to run at 100% for
extended periods of time, their voltage regulators will fail early due to thermal load
problems.

2.5W x 7 ports = 17.5W total draw. The switching regulators used in the hub for voltage
conversion are about 85% efficient, which means you need about 21W (17.5 / 0.85) or so on
the input side, plus another 2W for the hub itself. Call it 24W input just to be safe. 24W
/ 12V = 2A. You need 2A from your power supply at 12V.

I bought this hub originally because of the chip it uses inside, it was supposed to help with running more than one U3 at the same time, which it didn't. I think I'll play around with it a bit, but it's not looking like it's going to be suitable for 4 compac sticks if I want to do any overclocking.
