I believe some laptop wifi adapters are connected via internal USB, but not sure.
Your device is certainly not supported by
bwi(4).
And the FreeBSD bwn(4) driver, which has not been ported to NetBSD or OpenBSD, does not support it either.
Perhaps get a supported wifi adaptor (or replace the internal card
if possible*). If you opt for this - avoid Broadcom like the plague and thoroughly check that you're choosing supported hardware before buying.
*if it is a laptop some vendors only allow replacement with specific hardware. So be sure to research thoroughly.
