Hello,
I updated the OS of my new latitude 5450 (i7/gt840m) from w7 pro to w10 pro. After manually installing the w10 Broadcom smartcard reader drivers WUDF (found at dell support center) the login process is delayed by about 60 s (black screen+mouse pointer). The problem is resolved by disabling/uninstalling the drivers. Disabling w10 fast boot has no effect. BTW, the reader seems to be working fine.
Is there a fix to this problem? Thank you
