E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB AP Log Port.

I:* If#= 3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=03(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB AP GNSS Port.

I:* If#= 4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
E:  Ad=85(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=04(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB AP META Port.

I:* If#= 5 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=42 Prot=01 Driver=(none)
E:  Ad=86(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=05(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is ADB port.

E:  Ad=87(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=06(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB MD AT Port. User can use the port send AT command.

I:* If#= 7 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
E:  Ad=88(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=07(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB MD META Port.

E:  Ad=08(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB NTZ Port. User can use the port send MIPC command.
MIPC is an instruction set designed by MTK, similar to QCT's QMI

I:* If#= 9 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=option

E:  Ad=09(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
It is USB Debug port.

Sorry, I don't understand "not accepting modem control".
Should I set the non-MD ports to true?
for example: USB AP Log Port.
