- 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 librecmc distribution (kernel 4.14 using the old blacklist
- definitions).
- Lars Melin also writes:
- 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
