    USB: option Add blacklist for ZTE K3765-Z (19d2:2002) · 7e8e62e4

    The funtion option_send_status times out when sending USB messages
    to the interfaces 0, 1, and 2 of this UMTS stick. This results in a
    5s timeout in the function causing other tty operations to feel very
    sluggish.
    
    This patch adds a blacklist entry for these 3 interfaces on the ZTE
    K3765-Z device.
    
    I was also able to reproduce the problem with v2.6.38 and v2.6.39.
    
    This is very similar to a problem fixed in
