Bitmain Antminer U2

[Raptor2213]

Any way to clock past 2.2 with bfg?  I have two of these plugged in my desktop usb  ports running at 2.2 with 0 errors so I figure I can overclock it a bit more..... 

Yes, I posted about this a couple pages back: https://bitcointalk.org/index.php?topic=490559.msg6095762#msg6095762

Whats Multiminer and how about with CGMiner ?

Even if it's the same lined posted, I would have no idea how to use it since I don't recall a way to enter commands unless it goes in the config file in one way or another.

FWIW, here's my CGMiner config file.

Code:

{
"pools" : [
	{
		"url" : "stratum+tcp://stratum.btcguild.com:3333",
		"user" : "MoreBloodWine_Laptop",
		"pass" : "128"
	},
	{
		"url" : "stratum+tcp://us1.ghash.io:3333",
		"user" : "MoreBloodWine.Laptop",
		"pass" : "128"
	},
	{
		"url" : "stratum+tcp://mint.bitminter.com:3333",
		"user" : "MoreBloodWine_Laptop",
		"pass" : "128"
	}
]
,
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

Also another yes here. I'm running 5 U2+ all settling in a between 2.26 & 2.29 using a clock speed 0B01. One thing I discovered in with my USB hub/Antminers is that using speeds of either 0x01 or 0x81 with x being a hexadecimal number to set the speed, that bfgminer would work with it.
the only question was would the Antminer deal with it or give HW errors. I actually tested all of mine 2 at a time just so I could find out the rock stars vs the grinders.

Also there are number of threads here and elsewhere that I've read that the USB hub can be an issue. It tends to be an issue with how much power is going to the hub and can it provide enough power to the miners plugged in. Most of the USB 2.0 hubs that come with power supplies don't provide enough juice for U2+ miners. Ironically, the Amazon branded 7 port USB 2.0 port hub has a 4 amp adapter which should be good for our Antminers.

Now my question...I'm about reuse my wife's old netbook (currently Win XP) and was thinking of putting linux or unix on it. Suggestions on OS geared towards to mining?

Windows XP will likely only find a few of the miners.  Any linux distro should work, but I don't know of a specific one.  You might consider just getting a PI and running MinePeon.
So far as hubs go, I'm running two Anker USB 3.0 13-port hubs for 10 miners (5 each).  It's running all of them at 2.4 with 0% errors.

This remains to be seen.  English as a 2nd language at the minimum.

Are you on windows?  What version?  What mining software are you trying to use?
