[firmware] active antenna not detected on boot
|Reported by:||Quozl||Owned by:||mbletsas|

Problem: already plugged-in active antenna is not enumerated by operating system during boot. iwconfig does not show anything except msh0 and eth0.
Impact: very low, this is not an expected use-case. It complicates testing.
Workaround: physically disconnect and reconnect the USB plug of the active antenna. This results in msh1 and eth1 appearing in iwconfig.
Context: active antenna prototypes 0743 0666 and 0743 0652, two B4 systems, with operating system build 625.
Diagnosis: problem reproduced on two units, in either left or right USB sockets, with a warm reboot or cold boot after removing all power sources. lsusb shows the device exists on the bus. dmesg shows two discovery events but they identify eth0.
# lsusb Bus 001 Device 012: ID 1286:2001 Bus 001 Device 003: ID 1286:2001 Bus 001 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000
dmesg to be attached.
