Please do not use icarus options at all with these as the only thing you're likely to do is make it worse. Those options are of zero utility with the antminer U*s.

oh man, you just saved me
Haha, good luck to you. 
These can NOT be used for scrypt mining, instead buy a dualminer USB if you are looking for something cheap which mines scrypt.
oh man, you just saved me, I was moments away from submitting the order. Going to look into the one you requested.
Been thinking about buying the U1 or the U2 but need to know if these can be used for Scrypt mining?

where do you place the anu freq?
this is my config file, I am trying to make it run at 2gh/s but when i run it, it pops up and immediatelly disappears.
*Update, now it is working, I am using this now:
Code:
cgminer.exe --Anu-Freq:250 -o stratum+tcp://sha-256.megamultipool.com:5000 -u mikerbiker6.1 -p x --icarus-options 115200:1:1

Hi everyone. I have seen a lot of people struggling with setting up their Antminer u1/u2's. I created a quick guide for Windows users http://www.getfreebitcoins.us/bitcoin-mining/
I have copy-pasted the guide from my site below:
Antminer u2 Setup: *Note: You will need a powered USB hub (5-10amp per 10 slots) if you are running more than 1 u2 per powered USB hub on your computer.*
Go to: https://github.com/AntMiner/AntGen1 and open the Antminer u1 user guide (it’s the same setup process as the u2).
Follow the Install Driver section to part 4 (right before running cgminer). After the proper drivers are installed you will need to unplug the Antminer U2’s and plug them back in.
Download the newest version of CGMiner from here: http://ck.kolivas.org/apps/cgminer/
Windows install:
1. Unzip the files and note the location.
2. Open a Command Prompt.
3. Run the following script c:\yourcgminerlocation\cgminer-folder\cgminer --anu-freq 200 -o stratum+tcp://(enter your stratum pool info) -u Example.worker1 (enter your worker name) -p Password (enter your password).
4. You can also copy the command line into a notepad document and save as a .bat file.
5. After running the script, give cgminer about a minute to detect your miners (they will show up as ANU 0, ANU 1, etc), if any aren’t detected try unplugging then plugging in the ones that aren’t running. If that doesn’t work try lowering your ANU-Freq
Notes:
Additionally you can play around with –icarus-options if you know what you are doing, I have found the following to be the best options:
--icarus-options 115200:1:1
--Anu-Freq: This line sets the frequency of the miners.
**Note that Overclocking will void your warranty**
200: 1.6 Gh/s
225: 1.8 Gh/s
250: 2.0 Gh/s
275: 2.2 Gh/s (not recommended unless you modify the R1 and R2 resistors.)
A value above 250 typically results in the following issues if you don’t modify the resistors:
1. Too Many hardware errors
2. Not recognizing the devices
I personally have found that generally an ANU freq of 253.8 is the highest one should go on a U2 without modifying the resistors (but that’s just my personal experience, personally I don’t like to run the miners that hard).
