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

Tue Jan 23 14:42:26 UTC 2018

Hi Aleksander,

Sorry about the delay being able to test this. I saw you applied Bjørn's
patch to 1.18.2 and 1.20.0. I tested 1.18.2 now and unfortunately it didn't
work. Same result as before with the applicationnot recognising the USB2
port, rebooting and recognising USB3 port.
