25.7 Series / 4g USB WAN not working
August 08, 2025, 02:16:10 PM
Hi I have tried to connect USB 4g modem to my OPNsense router firewall. It is a bare bone device. I intend to use this USB $g modem as a WAN fail-over option. However I am getting an error relate to the device.
Notice, kernel, [114] ugen1.2: <vendor 0x1286 product 0x4e31> at usbus1 (disconnected)
Notice, kernel, [114] ugen1.2: <vendor 0x1286 product 0x4e31> at usbus1
Notice, kernel, [114] usb_alloc_device: Failure selecting configuration index 0:USB_ERR_IOERROR, port 7, addr 56 (ignored)

I tried using the same usb device on a vanilla FreeBSD VM as well as a separate OPNsense VM. in both those cases, USB 4g WAN device is working fine.

what could be wrong?
