    Name/email should preferrably be the same as the one in your signoff. 
Besides, the email address is not valid here.

Any idea what interfaces 1 and 5 are?  Is one perhaps a pseudo-ethernet
interface that could be used instead of PPP?  What's the lsusb -v output
for the device?

Daniele has already posted a patch adding intf #5 to qmi_wwan, so I
assume that is verified to be a QMI/rmnet interface.

But I was wondering about #1 too, if that indeed is a vendor specific
interface providing a non-serial, non-rmnet function.  What could that
be?

The output of lsusb for interface #1 is the following:

Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber        1
      bAlternateSetting       0
      bNumEndpoints           2
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceSubClass     66
      bInterfaceProtocol      1
      iInterface              0

It should be an adb device, so probably it is not needed to blacklist
it. Should I resend a new patch with only interface #5 reserved?

Thanks,
Daniele

You could have used USB_DEVICE_AND_INTERFACE_INFO() matching on all
ff/ff/ff to avoid blacklisting the adb interface, but IMHO the patch is
fine as it is.

This being an Android device raises another question though: Are these
interface numbers static?  I assume you can e.g. disable adb?  What
happens to the descriptors then?  Does the device change pid, or are the
interfaces renumbered?

Thanks, next time I'll follow that way.

This is the device:

http://www.telit.com/en/products/lte.php?p_id=421&p_ac=show&p=130

It is not an Android device, but an AT command based modem. I don't
really know why there is an adb interface, but I am quite sure that
you cannot disable it and the interface numbers should be static.

However, if I find that this is not true, I will take care of sending
a new set of patches for addressing the issue.

Regards,
Daniele

Nevermind, I see the QMI patch for the device now on netdev.
