What is USBDK? USBDK, short for USB Driver Kit , is an open-source Windows kernel-mode driver developed primarily by the VirtualBox open-source project (Oracle) and also utilized by other virtualization platforms like QEMU. Unlike standard Windows USB drivers that assume exclusive physical access to a USB device, USBDK is specifically engineered to facilitate high-performance USB redirection from a host operating system to a guest virtual machine (VM).
In essence, USBDK acts as a proxy. It sits between the Windows USB stack and a virtualization application, intercepting USB commands and efficiently forwarding them to a VM. To understand USBDK's value, it helps to contrast it with traditional methods of USB redirection. What is USBDK
