Ticket #6600 (new defect)
USB enumeration fails on warm reboots of active antenna
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
