After a warm reboot, the active antenna will fail USB enumeration.
The same failure can be triggered by reloading the ehci_hcd module:
{{{
# rmmod ehci_hcd; modprobe ehci_hcd
usb 1-4: can't set config #1, error -110
}}}
JTAG debugging reveals that the device fails to initialize endpoint 2.
Note that this does not happen on xo's because the wireless device is
always reset.
firmware: 5.110.20.p49 and 5.110.22.p4
