[Q] Xperia Ray not recognized by Ubuntu - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi
i am trying to connect my Xperia Ray on my computers running Ubuntu 13.04 but i am having troubles. Adb and Fastboot are not detecting any device.
The funny thing is that my other phone, a Nexus 4, is correctly detected and working.
My Xperia Ray was flashed with CM 10.1 + default CM 10.1 kernel and i cannot even go in fastboot mode by pressing Vol Up at start: the blue led is blinking for half a second and then the charging screen is appearing.
Have anybody of you the same issue with CM 10.1?
How can i flash a different kernel in CWM recovery to unlock fastboot?
Best regard

Volume up at start? You just have to push the volume up button when it's turned off and connect the usb to your PC. Then Ubuntu should detect it
For me my xperia mini pro and my nexus 4/7 are working great on Ubuntu 13.04

I do already it.
When i do this, the blue led fblinks for haf a second and then goes in charging mode.
Running dmesg on linux, it says "failed to enumerate device on port 2"
It's not a problem of linux, because the Nexus 4 is working fine with it.
I think it's a kernel issue, but how can i flash a new kernel without entering in fastboot mode?

If your device is powered on, are you able to run adb? Try to run adb devices and see if it comes up there
If yes use adb reboot bootloader (I guess) for fastboot mode

The problem is that neither adb or fastboot work..
using dmesg command, the result is:
Code:

and adb shows "no devices found". It happens also when i am in CWM and when i do "mount usb", it doesn't show anything

Did you add the usb driver in /etc/udev/rules.d/99-android.rules?
How did you install fastboot/adb? Using the following commands?
Code:
# sudo add-apt-repository ppa:nilarimogard/webupd8
# sudo apt-get update
# sudo apt-get install android-tools-adb android-tools-fastboot
Try it again and afterwards connect it

i've tried with this ppa on Ubuntu and then also under Windows 8,but it's not working.
the device doesn't detect the pc, but just uses it like a charger, and the pc doesn't recognize the device. I've used different cables (the original one + another one of a Nexus 4) but still it isn't recognized, while any other android device works.
I guess it's a problem related to the usb port of the phone.
