Well, the driver expects exactly two interfaces with the appropriate
classes as described in the ACM spec. The number of endpoints on these
interfaces isn't checked.
So this would probably work:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 11 Spd=12 MxCh= 0
D: Ver= 1.01 Cls=02(comm.) Sub=00 Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=xxxx ProdID=xxxx Rev= 0.00
S: Manufacturer=xxxxxxxxxxxxxxxx
S: Product=xxxxxxxxxxxxxx
S: SerialNumber=Serial Number
C:* #Ifs= 3 Cfg#= 1 Atr=e0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl=128ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)
E: Ad=8a(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=0b(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=83(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=06(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
But this would be better:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.01 Cls=02(comm.) Sub=00 Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=xxxx ProdID=xxxx Rev= 0.00
S: Manufacturer=xxxxxxxxxxxxxxxxxxx
S: Product=xxxxxxxxxxxxxxxxxxxxxxxxxx
S: SerialNumber=Serial Number
C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl= 32ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)
E: Ad=8a(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=0b(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
C:* #Ifs= 2 Cfg#= 2 Atr=e0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl=128ms
E: Ad=8a(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=0b(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=83(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=06(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
Anyway, the driver can be modified to ignore any interfaces beyond 2.
