For a device to be supported by HWI, it must:

Use open source firmware as much as possible
- Entirely closed source devices will be rejected
- Devices may have closed source firmware components if required to under a NDA (e.g. a secure element with NDA)
Publicly documented communication protocol
- It is preferred to both document the protocol and provide a Python library for using it
- The library, with its own documentation, can suffice as "publicly documented"
Either (but preferably both):
- A simulator/emulator is available for automated tests to be run
- A promise to maintain and support from the vendor:

Device support may be dropped:

If promised vendor maintenance and support disappears
- If there are continuous issues with the device and the vendor has failed to provide support and updates
If the device no longer receives security devices and there are known vulnerabilities and issues
