I'm trying to setup an Antminer U2 with multiplool but can't seem to get it to work.

I'm using the command line:

                        cgminer.exe -o stratum+tcp://us-east.multipool.us:9999 -u jburke4.1 -p x
 
With cgminer I get "No devices detected" I see the device listed in both device manager and in Devices and Printers as Silicon Labs CP210x USB to UART Bridge (Com4)  It does eventually seem to find the device but It does not appear to be doing anything productive.  I keep getting in an endless loop:

                        Pool 0 difficulty changed to 256

I have tried every server they have listed and keep getting the endless difficulty changed loop.  I tried the antminer pool as well withthe exact same issue.

Also once working should I adjust the Bits per second in the hardware properties?  It's currently set at 9600.

Windows 8.1
cgminer 4.6.1 x64

I have used all of their pools with the same result.  I have even tried Antminer pool as well figured that if that doesn't work nothing will but I just get the endless difficulty changed loop.  It's been running that on Antpool for about 20 minutes now.







Per the earlier advice I made a new thread at:

 https://bitcointalk.org/index.php?board=76.0

Installed Zadig and configured per instructions on the website.  Also using the information from multipool for their ASIC server I am using this command line:

cgminer.exe -o stratum+tcp://us-east.multipool.us:8888 -u [MYUSERNAME] -p [MYPASSWORD]

I am still getting the endless difficulty changing loop.

It's running now but without results.  Just endlessly looping the statement about changing the difficulty.

So far no luck, now the CMD interface is blank.  Tried running it a couple times, letting it just run for a while to see if maybe there is an issue on the other end.

Giving it a try now.

Thanks
