I found a thing from Adafruit for 3.8 kernel https://github.com/adafruit/wifi-reset
It was nice but is relying on iwconfig to do its magic So I rewrote it for connman https://gitlab.com/petelawler/wifi-reset Haven't tested it really with anything apart from 4.4 and 4.9 kernels. Your mileage may vary. Works for me. Like all hacks, it's a not a good hack because it's clean but because it works. I've not looked deeply under the hood but I suspect what's going on is that connman is firing off everything before the USB bus is fully enumerated and necessary firmware is loaded. At least, that's my wild stab in the dark.
