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
