Is your device a WinUSB-rebind candidate?

Seven yes/no questions about your device. All seven answered = verdict below the form. The result page's URL is shareable — send it to a colleague or paste it into a support ticket.

1. Does the device use only bulk, interrupt, or control transfers (i.e. NOT isochronous, used for real-time audio/video streaming)?
2. Does the existing driver run entirely in user mode — no kernel-mode IOCTLs, no kernel-mode callbacks, no integration with other kernel subsystems?
3. Is the device class anything other than HID? (HID-class devices already expose user-mode access via the Windows HID API — rebind is redundant.)
4. Is it acceptable that only one process at a time accesses the device? (WinUSB uses a single-handle model — multi-process needs an arbitration layer this toolkit does not include.)
5. Are sub-millisecond timing guarantees NOT critical to your use case? (The Windows user-mode scheduler cannot guarantee them.)
6. Does the existing driver operate on the USB device standalone — no entanglement with filesystem, network stack, GPU, or audio stack?
7. Does your vendor's license or NDA permit driver replacement on customer machines? (If unclear — answer yes; answer no only on explicit prohibition.)
