Subject: Sony Ericson w995 does not local net mode

Hello guys,


Please CC me for Questions and answers


I have got an w995 Sony Ericsson, but i cant make local net via usb with it.
I uploaded a recent software version: 1215-7995 R1HA036 091216



First for the usb ID guys since the ids are not yet in usbid.txt:

PC mode            (for Windows(r))
  usb 1-4: New USB device found, idVendor=0fce, idProduct=e112
  usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 1-4: Product: Memory Card (MSC)
  usb 1-4: Manufacturer: Sony Ericsson
  usb 1-4: SerialNumber: 3582180356368990
  usb 1-4: configuration #1 chosen from 1 choice


USB mem. device        (File transfer)
  usb 1-4: New USB device found, idVendor=0fce, idProduct=2112
  usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 1-4: Product: Sony Ericsson W995
  usb 1-4: Manufacturer: Sony Ericsson
  usb 1-4: SerialNumber: 3582180356368990
  usb 1-4: configuration #1 chosen from 5 choices
  Initializing USB Mass Storage driver...

Other OS         (E.g. Mac(tm), Linux(tm))
  usb 1-4: New USB device found, idVendor=0fce, idProduct=d112
  usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 1-4: Product: Sony Ericsson W995
  usb 1-4: Manufacturer: Sony Ericsson
  usb 1-4: SerialNumber: 3582180356368990
  usb 1-4: configuration #1 chosen from 1 choice

MTP devices        (E.g. certain car stereos)
  usb 1-4: New USB device found, idVendor=0fce, idProduct=0112
  usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 1-4: Product: W995
  usb 1-4: Manufacturer: Sony Ericsson
  usb 1-4: SerialNumber: 3582180356368990
  usb 1-4: configuration #1 chosen from 1 choice


Now USB mass storage works, PC mode doesnt bother me much, but i 
actually excepted Other OS mode to work, which it does not.

following are the logs:
