USB flash drives with hardware encryption typically consist of an encrypted storage partition and a second utility partition that contains a utility for unlocking the encrypted partition. For USB Flash Drive devices, achieve the best user experience using the dedicated client drive mapping/dynamic thumb drive mapping HDX virtual channel that also performs optimization. Dedicated USB mass storage device blocking software such as AccessPatrol is easy to manage, allowing the modification of policy updates to be delegated to less technically savvy users. After following these steps you will be blocking USB mass storage devices while still allowing keyboards and mice to function.

Data transfer at 480 Mbps is a key addition to the USB 2.0 specification. Since USB 2.0 promises compatibility with USB 1.1, it must be able to communicate properly when connected to a USB 1.1 system .
