Hi Kyosti, Sorry, I reread your first reply and it became clear what you meant when looking on the Chomebox's /var/log directory. I found the port at the back corner of the Chromebox is numbered 2-1.2. None of the external ports connect as 1-1.2. Connecting the phone with the EHCI debug device enabled kernel to the 2-1.2 port and booting Ubuntu on the Chromebox I see the following in kmesg:
[ 2.008799] usb 2-1.2: new high-speed USB device number 3 using ehci_hcd [ 2.031628] atkbd serio0: atkbd: SETLEDS failed [ 2.049059] init: plymouth main process (93) killed by ABRT signal [ 2.049409] init: plymouth-splash main process (398) terminated with status 2 [ 2.094946] usb 2-1.2: unable to read config index 0 descriptor/start: -32 [ 2.097301] usb 2-1.2: chopping to 0 config(s) [ 2.099611] usb 2-1.2: New USB device found, idVendor=0525, idProduct=c0de [ 2.099615] usb 2-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 2.100136] usb 2-1.2: no configuration chosen from 0 choices I can post the full logs if needed but they are quite long. I tried different values for CONFIG_USBDEBUG_HCD_INDEX on the Coreboot build. I tried values of 0,1 & 2 but still didn't see any output on the EHCI debug device with 'cat /dev/ttyGS0' Regards, Tim.
