Subject: USB: serial: option: blacklist unused dwm-158 interfaces
|
|
|
|
The dwm-158 interface 4 and 5 doesn't answer to the AT commands
|
|
and doesn't appears a option interface.
|
|
Tested on openwrt distribution (kernel 4.14 using the old blacklist
|
|
definitions).

Blacklisting interface 4 and 5 is correct because:

|
|
MI_00 D-Link Mobile Broadband Device (cdc_ether)
|
|
MI_02 D-Link HSPA+DataCard Diagnostics Interface (also ppp modem)
|
|
MI_03 D-Link HSPA+DataCard NMEA Device
|
|
MI_04 D-Link HSPA+DataCard Speech Port
|
|
MI_05 D-Link HSPA+DataCard Debug Port
|
|
MI_06 USB Mass Storage Device
