i could not get my s7 to get recognized as well,
until i did the following
1) i got the UPDATED(most recent) 2.2 from huawei website.
then
2) Download the official drivers and installed but no success.
then
3) i rooted my s7
it was at the beginning of rooting(Super One click 2.3.3) that I could not get my s7-104 "connected". I had tried prior versions of Super One Click with no success. But when using 2.3.3, SOC could not "connect", it kept coming back with "Abort, Retry or Ignore". Of course I would click "Abort"
when it first appeared(On step 3), but i was getting frustrated and selected "Ignore" on my next attempt. It was then the SOC asked me if I wanted to use it's on DRIVERS. I selected yes. And it took.
SOC then continued through the remainder of the STEPS(3 - 5).
I repeated SOC again and it completed with no STEP failures.
here is my SOC "successful" log
