When I connect the Netmod device that acts as an ISDN
modem but the acm driver is not loaded for the device.
It should be "Driver=acm" but it is "Driver=(none)".

The device parameters in the firmware seem to be ok.

Please look below

(Taken from my system with the netmod connected in a
USB port)
(Kernel 2.6.8-2)
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 4
Spd=12 MxCh= 0
D: Ver= 1.10 Cls=02(comm.) Sub=00 Prot=00 MxPS=16
#Cfgs= 1
P: Vendor=0bf1 ProdID=0001 Rev= 1.00
S: Manufacturer=Intracom S.A.
S: Product=NetMod USB
S: SerialNumber=Firmware Ver 1.0
C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr= 0mA
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=10ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00
Driver=(none)
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

Below is the output I should have according to the manual.

(Taken from the netmod installation manual)
(Kernel 2.2.X)
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12
MxCh= 0
D: Ver= 1.10 Cls=02(comm.) Sub=00 Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=0bf1 ProdID=0001 Rev= 1.00
S: Manufacturer=Intracom S.A.
S: Product=NetMod USB
S: SerialNumber=Firmware Ver 1.0
C:* #Ifs= 2 Cfg#= 1 Atr=60 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01
Driver=acm
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl= 10ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00
Driver=acm
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl= 10ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl= 10ms

The output from the command
usbmodules -d /proc/bus/usb/001/002
is
cdc-acm

while for

usbmodules -d /proc/bus/usb/001/001
and
usbmodules -d /proc/bus/usb/001/003
is
usbcore.

I have included the output from `cat
/proc/bus/usb/devices` for the specified device.

Further information on the device can be found in
http://netmod.intracom.gr/pdf/pdf_engl/usb_linux_22x_en.pdf

Kind regards,

Fafakos Panayiotis.
