UsbDk at a Glance 

  1. 1. UsbDk at a Glance
  2. 2. Meet UsbDk UsbDk stands for “USB Development Kit” Universal engine for exclusive access to USB devices on Windows OSes Full user mode API for all device operations Designed to support all types of USB devices Generic API to allow wide range of use-cases Designed with HCK certifications in mind Hiding engine for total detachment of USB devices from OS software stack
  3. 3. Feature set Totally dynamic device capture
 No INF files and no self-signing needed
 Any device can be captured Totally dynamic device detachment
 Any device or class of devices may be hidden
 Prevents Windows from showing "New Hardware” pop-ups for devices without in-box drivers
 Great for security solutions Co-existence with original device driver
 When the device is not captured original driver is loaded by the system automatically
 If user mode client terminates unexpectedly for any reason system reverts to original device driver immediately Supports for all types of devices and interfaces
 Bulk, isochronous, composite, HID, etc. Being USB filter driver doesn't require WHQL-ing
 as per Microsoft requirements
  4. 4. Advantages over WinUSB Full feature parity Full support for isochronous devices Full support for composite devices No INF files and no signing needed Open source and community supported
