Thank you for the hint, but it seems it is already in 13.2. https://cgit.freebsd.org/src/commit/sys/dev/usb/usbdevs?h=releng/13.2&id=226fef966a1f234d871c199af77ca411f87d2389 It looks like idProduct = 0x1a2b is just the fake CD-ROM drive. Should I found some different id and add it? I am sorry for maybe stupid question but this is the first time I play with USB WiFi dongle on FreeBSD. Kind regards Miroslav Lachman
