When I send a referral my friends just get a text that says "Hey, let's switch to GetGems %1$d"  Is anyone else getting this?  What am I doing wrong?  I'm using the new iOS app.

I finally got mine to work.

I found this file:
cgminer-run-windows-20141110.zip   detect 4 chips during device detect procudure for U3
at:
https://www.bitmaintech.com/support.htm?pid=007201404130633105772QFG6R2u0635

so I decided to use it to test my U3.  It started hashing right away. So I edited the autorun.bat for my worker and it's going at about 49 Gh/s now.

thanks for the help

I just got one of these, too.  I can’t get cgminer to see it.  I’m on Windows XP with the “official” Bitmain cgminer 4.6.1 and the Zadig driver installed.  The Device Manager shows USB device “CP2102 USB to UART Bridge Controller".  In cgminer if i hit “U” for USB devices then “L” for list all know devices I get nothing.  Running cgminer from the .bat gives “No devices detected!’ and “Waiting for USB hot plug devices or press q to quit.”  Any ideas?  Why does device manager see it but cgminer doesn't?

Thanks
