Don't work with OneplusOne boot ThinkPad

[tux4us]

OneplusOne UT 16.04 dev

I mount a ubuntu-18.04.2-desktop-amd.64.iso and try to boot with a ThinkPad T430. In bootmenue select USB-CD:Linux File-Store Gadget and ENTER , the screen is short flickering and then the bootmenue is back and so on. On Nexus5 it works fine.

I can't debug on my own OPO atm as it's stuck on the "The battery is too low" screen and my power button is broken. Could you please use adb shell to get the contents of the following files:

cat /sys/devices/virtual/android_usb/android0/enable
cat /sys/devices/virtual/android_usb/android0/functions
cat /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file

EDIT: please try both unmounted and with iso mounted.

Unmounted:

cat /sys/devices/virtual/android_usb/android0/enable
1
cat /sys/devices/virtual/android_usb/android0/functions
mtp,adb
cat /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file
Permission denied

ISO mounted:

cat /sys/devices/virtual/android_usb/android0/enable
1
cat /sys/devices/virtual/android_usb/android0/functions
mass_storage
cat /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file

I tryed to boot 2 Lenovo ThinkPads with 2 OPOs with ISOdrive. Every try fails. Bootmenu shows: Linux File-Stor Gadget (it's different to: cat /sys/devices/virtual/android_usb/android0/f_mass_storage/inquiry_string Linux File-Stor Gadget0000 )

Boot another PC different to ThinkPad, it works well with both OPOs. Bootmenu shows: Linux File-Stor Gadget0000

Another interesting thing, could you please show the directory contents of lun using:

ls -lah /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/

Could you please try the following:

1) start with no mounted iso 2) echo 1 | sudo tee /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/cdrom 3) mount iso.
