Problem: After installing, you see a “yellow bang or exclamation icon next to BROADCOM USH DEVICE CODE 28” under Device Manager

Cause: Most likely due to Broadcom
Solution:

• Make sure Windows SP1 is installed
• Make sure .Net Framework 3.5 is installed
• Download “ControlValutDriver w/o Fingerprint sensor” executable (dated October 2015) – Dell download link is here at https://www.dell.com/support/home/us/en/04/product-support/product/latitude-e6510/drivers (direct link
• Reboot and the icon will disappear

You will want to check Windows Update to apply security patches to .Net Framework 3.5, then auto upgrade to .Net 4.7.2
