Though its already merged into main, I did validaiton to ensure end-to-end testing (discovering usb cameras, adding them egex metadata and rest-api's) works correctly both with 'path' and 'paths' fields and it looks good. Validated with below combinations of code:

1. Latest (main branch) egex and Latest (main branch) USB code - works with 'paths'
2. Latest (main branch) egex and 3.0 USB code - works with 'path'
3. 3.0 egex and Latest (main branch) USB code - works with 'paths'
4. 3.0 egex and 3.0 USB code - works with 'path
