I created this account just to thank you for providing this http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS035697 link. It solved my unknown device issue.
All I did was do a clean Win7 install. The PC in question had Win7 pre-installed but it was prebundled with all their crapware. I wish we had a choice of crapware free when buying their machines.
The Lenovo System Update didnt install the drivers (thats pretty poor if you ask me, as that what its designed for).
I found speaking with lenovo tech support was also a wast of time, unless i wanted to pay for their Premium Support.
Good thing they atleast keep this forum as a alternate way for their customers to assist one another.
