warning message[0] and the usb3 port become unusable (sometime i get an other
error message too[2])
then when disabling the runtime PM of the controller and plugout/plugin the usb
device, I don't get the warning message

I have deleted the bios-outdated-6.80 flag as this bug affects peoples
with other BIOSs and it stills happens even after updating the BIOS as
long as the patch posted by @henrix was not applied to the running
kernel

I have updated the bios. but I'm still getting the same ACPI errors on
dmesg output.
I noticed this error on dmesg output on both ubuntu and archlinux many times:
usb 1-3: device not accepting address 4, error
@henrix: ok, i'm going to try it
@penalvch: Toshiba Bios executable requires a running windows 8 system on the
laptop (neither wine nor freedos nor virtual machine worked), so, i may not be
able to update the bios anytime soon

just an hour later, i get the same bug :( it seems not fixed yet on
linux 3.15-rc1
that's a part of dmesg with the lastest error:
[ 7640.417057] usb 1-1.2: new high-speed USB device number 9 using ehci-pci
[ 7640.511625] usb 1-1.2: New USB device found, idVendor=12d1, idProduct=1506
[
ok, i'm currently running mainline kernel on recovery mode, i will need
at least two days to check if this bug not fixed because it happens on
Trusty kernel rarely (one or two times the whole day)
