The only option supported on the official cgminer for antminer U2s is the --anu-freq option. The current good working cgminer version for U2s is version 4.3.5 (as opposed to a fork based on an old outdated unsupported version you seem to be trying to use) does not want you to use nor does it support the bmsc-options bmsc-freq options. Grab the latest official cgminer from the official downloads in the top post from here:

Then you can get support from that same official thread.
Topic: cgminer with antminer u2 question (Read 1251 times)
So I am having a problem getting my miner to connect to anything other than one place.
I go to a command prompt and enter this:
cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://192.241.166.175:5000 -u -p --bmsc-freq 0781
and it connects and mines ok.
If I put in the hostname,
cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://east-us.megamultipool.com :5000 -u -p --bmsc-freq 0781
I get this:
[2014-06-19 21:33:05] -----------------start nonce------------------
[2014-06-19 21:33:05] Bmsc send golden nonce
[2014-06-19 21:33:06] Probing for an alive pool
[2014-06-19 21:33:06] Failed to resolve (?wrong URL) east-us.megamultipool.com:
5000
[2014-06-19 21:33:16] Waiting for work to be available from pools.
I get this same error with any pool I try... I can do an nslookup and get the ip address.
I have the same issue on two different computers, so I can assume its something that I am doing wrong.
The miners will work with megamultipools ip only. No other pools work.
I have tried this using cgmin 3.12.0 and 3.8.5
I am on windows 7 and have replaced the drivers with zdiag, and they work correctly with one single address only.
Anyone have thoughts? Im pulling out my hair,.
