The usbdk project is not published by Microsoft. Instead, it is an open-source initiative, most commonly associated with virtualization software like VirtualBox, QEMU, and certain Android emulators (such as Genymotion). The library is often bundled or recommended to enable USB passthrough—allowing a virtual machine (VM) to directly access a physical USB device connected to the host computer.
UsbDk serves the following primary functions:
You may not need this driver package at all. Consider these alternatives depending on your use case: usbdk1022x64msi
| Use Case | Alternative | Pros | Cons | |----------|------------|------|------| | VirtualBox USB passthrough | Oracle VM VirtualBox Extension Pack (official) | Signed by Oracle, regular updates | Not open-source, requires Oracle account | | QEMU on Windows | Spice USB Redirection (usbredir) | Better performance, integrated | Complex setup | | Android ADB over USB | Google USB Driver | Official, stable | No VM support | | Raw USB access for development | libusb / WinUSB (via Zadig) | Lightweight, no MSI needed | Manual driver assignment |
If you cannot use usbdk due to compatibility issues, consider these alternatives: The usbdk project is not published by Microsoft
| Alternative | Best For | Key Difference | |------------|----------|----------------| | VirtualBox USB Passthrough (legacy) | Older VMs on Windows 7 | Less stable, limited to USB 1.1 | | VMware USB Arbitration Service | VMware Workstation/Player | VMware’s native driver, more robust but proprietary | | RDP Easy Print / USB Redirection | Native Microsoft RDP | No extra driver needed, but less device support (e.g., no mass storage redirection) | | libusb-win32 | Developer/debugging tools | User-mode only, slower performance for bulk transfers |
For most users, usbdk remains the gold standard for open-source USB redirection on 64-bit Windows. If you cannot use usbdk due to compatibility
