Hi, I'm currently experiencing the same issue with the same driver ( it is not the only one that I can't upload but the only one I need )
I also installed these 2 KB but it did not work either.
I am still looking for a solution but if you find one, I would love to know it. Regards, Thomas EDIT : I need to import it on a Windows server 2008 with SCCM 2012 SP1 and it's not working, I tried on a Windows server 2012 with SCCM 2012 R2 and it's working.
