Uniden have TWO driver versions for the BC125AT. For Win.7 they originally had BC125AT_CDC_WIN7.inf. For Win10/W11 which required signed drivers they have the Uniden Universal Serial Driver.
The Uniden Universal Serial Drive *should???* work on W7 however for BOTH W7, 10/11 you must have BOTH the .inf and .cat files. .inf file will not work on it's own.
