I should have summarized this, but I know I can run the single cgminer and a stick from a usb port on the laptop or docking station. Can I also run an externally powered hub with a stick running a separate cgminer, its own settings, etc?
Add --usb :1 to the bat file for each stick. When you launch cgminer that command tells it to only initialize 1 usb device. That way you can run two instances of cgminer and each will only control a single stick.
I just did this and now I have 1 stick on a laptop port @ 125 freq (0.5A) and one on a hub at 262.5 freq (1.0A, which is what each port on this hub is rated to support), both sticks pointed to the club.
I think that shares summary would be really cool, it would help facilitate a fair spread of the block reward after this initial period is over. In which case I would probably just point all my solo miners to the club.
U for Usb, my bad
I didn't use common sense when perusing the readme.
Thanks Mikestang!
Edit:
I probably should have put this in the review thread, but it is here now. IF you guys think it makes any real difference tell me and I will move it.
To explain what I did with this information.
I placed one stick running at 125 in the Laptop USB port to maintain pool presence no matter what. This laptop has an LTE cell connection so if worse came to worse I am online when the bomb drops.
I placed 4 sticks spread out nicely in my 13 port hub.
Stick #2 is in slot 13 right next to the (charge only) port where I connect the arctic breeze blowing on stick #2.
Stick #2 is ran at 275 Mhz for about 12 hours with 0 hardware errors and I just bumped it up to 300.
The other 3, sticks #3, #4, and #5 are running at 250, 175, and 150 beautifully. The only one with a HW error is #3, and that is HW:2 in the same 12 hours. I am calling them all stable.
I run a separate cgminer instance for each one. Why?
I control each one independently. But why?
One reason is I do not have another fan to fit in this area comfortably yet and I want to overclock. So I keep the fan pointed straight on stick #2 while I have it connected to my usb power monitor. I can hold my fingers on it indefinitely at 300. I am pulling 1.36 amps @ 4.92 volts.
I think I am hitting the ceiling of where this hub will reach and be stable.
All of the other sticks stay operational, on the same PC, and I can do whatever I want with this one, or any other individual stick.
I have a Y cable I found on Amazon. IT wasn't an easy find, it was hard work, and cost me ten bucks, but I wanted it sooner than the slow boat from China. This one was prime as well, so no shipping and received it in two (actually three but I'm not arguing with them) business days. IT is supposed to be here tomorrow, and then I can really see whatsup. I will get another fan ready today.
At the moment I have them all set to balanced between ck solo and my main kano account, but this is only temporary fooling around because balanced has never worked as well as it should on my main mining rigs, so I do not expect it to start working now. By not working I mean if I add the hash from the two balanced pools I never reach what I get solo to either one. I plan to go back to a failover setting once I collect enough data to be happy with my theory that sticks suffer the same problem.
Overall, running the separate instance is giving me freedom with one good hub. Klintays hubs are probably better, I think they go to 2 amps per port if you do not populate them all, but again, once I made up my mind, I wanted it yesterday, so I went with this used Anker. Helluva deal, and it is USB3, which I know doesn't matter to most, but in my thinking true USB3 is future proof for other projects, provides 900 ma per port at the minimum. I am running it on a USB2 port on the same laptop stick #1 is running on.
This USB power measuring device has a reading in the bottom right corner and describes it as capacitance. I'm not sure what this is telling me yet. Don't get me wrong, I know what capacitance and a capacitor are, I simply do not know what they are telling me in this context, yet.
Here are some pics. The first is a bit blurry, sorry.

I want one of Klintays 19 port hubs and another 15 sticks to play with.
I am so jealous of you guys who were around during the days when this was the way to mine, or GPUs, or CPUs.
This is the kind of stuff that teaches people things, you never reach the end of possibilities due to your cash availability.
This can start someone down the road of dreaming big and eventually doing big, while providing the experience on a small scale.
For the young people out there, look at this as something to add to your arsenal of skill sets. The future is software and electronics engineering. Grab anything you love in either of those two fields and run with it.
