(( Problem Resolved - Had to get driver for Chinese Clone - see below ))
Hi. I am having a problem installing the USB driver for UNO. It has never worked, and the board is the same as the day i received it (3 weeks ago). IDE itself seems to install fine. i have read a similar post in this forum -- (WIN7) Arduino Uno not reconized on computer -- but doesn't seem to be the same problem, plus his board is "3 or 4 years old"
In Device Manager, it appears in "Other Devices" as USB2.0-Serial, not in ports as troubleshooting / forum / google search seems to expect. I try to Update Driver, and browse to C:\Program Files\Arduino\drivers but windows could not find find driver software for your device.
IDE > Tools > Board is set to "Arduino / Genuino UNO"
IDE > Tools > Port > Serial ports is greyed / disabled. set on COM3 (which i know isn't right)
Two LEDs (both RED - one flashing) appear when i plug board in.
I purchased 2 boards as a set from China (i am in Australia) and it does NOT say Arduino OR Genuino on it, just UNO. doesn't say R3 on the board, but it did say on the aliexpress*com ad i ordered them from. [Is it possible this is a clone and not genuine?]

Arduino IDE version - 1.6.12 (1.6.10 did the same thing) - downloaded 3 hours ago from here.
Windows version - Window 7 Starter (service pack 1) - 32 bit
This problem occurs on both my windows 7 laptops, the other isn't windows 7 starter though. 2nd board i gave to a friend, he is running Linux and not using this IDE (coding from text editor instead) and he reports NO problems at all.
Any advice appreciated... x Caitlyn
