Where do you get that one from?
Support for auto focus is in OpenCV when handling V4L2 sources, but from my reading of the source it is not mandatory for the device to support it. Doing so would be surprising as it would significantly reduce the number of devices that could be used with OpenCV - not a good way to encourage people to use your software.

Or use the Raspberry Pi specific interface library for OpenCV - https://github.com/cedricve/raspicam
No requirement for auto focus there.

Even wireless ones, but driver may not be support?
Most of them show up as USB HID (Human Interface Device), aka a keyboard. On barcode read they just create keypress events for the read data, so no specific driver required.
