Confirm, it appears as "ugen0.3: <Realtek USB 101001G2.5G LAN> at usbus0" in pfSense, yet no driver is linked. It seems pfSense or FreeBSD lacks standard USB Ethernet support, which isn’t surprising given the platform’s limitations. My setup functioned on Linux but kept sending repeated "link up" alerts to syslog and didn’t handle Junbo Frames well. Fixing the Linux driver resolves both issues but forces a full recompile after each kernel update—no official driver exists for that kernel version. Realtek chose not to maintain support for this adapter, so they stopped updates once basic operation was stable. Personally, I find USB devices frustrating; both the Realtek 2.5Gbit and Aquantia 5Gbit models refuse to work after rebooting from Windows back into Linux without proper reconnection. By the way, FreeBSD also doesn’t support the Aquantia Multi-gig chips unless you manually compile an experimental driver.
