[PATCH] qmi-firmware-update: support USB3->USB2 mode changes during upgrade

Tue Jan 23 15:17:42 UTC 2018

Hi Bjørn,

Checked that now and no peer file exists in /sys/bus/usb/devices/2-2/. I
don't know what a peer port is so need to look into that.

2-2:1.0/             bMaxPacketSize0      devpath              quirks

2-2:1.10/            bMaxPower            driver@              removable

2-2:1.2/             bNumConfigurations   ep_00/               remove

2-2:1.3/             bNumInterfaces       idProduct            serial
