I keep working on the problem.
The reason SecureAccess doesn’t work on USB 3.0 Flash Drive plugged into USB 3.0 jack could be lack of native USB 3.0 support. In my case it means that Intel Z68 Express chipset has no native USB 3.0 support while motherboard ASUS P8Z68-V PRO is equipped with two USB 3.0 controllers ASMedia ASM1042.
Intel 7 series Express chipsets have integrated USB 3.0. **bleep** it.
Or is it the ASMedia driver fault?
Two different SanDisk Technical Support girls replied to my requests :dizzy_face:
They are very concerned
