No, sorry, that was with 4.4. As you hit "PM regression with commit
5de85b9d57ab PM runtime re-init in v4.5-rc1", I thought I'd avoid
v4.5-rc. 

(I assume I have to insmod and rmmod, right? Because powersave is not
entered if I simply compile-out usb).

Would you have commit ids for those rmmod fixes? It might be good to
push them into stable, and I should try again with them applied...

Thanks and best regards,
