Well, Amit Ji, I would try but I think that I had tried it earlier and I do
not remember now what was the output. However, I will let you know the
results of this command later. Meanwhile, I had located a helping document
namely acm.txt from the RH installed on my system and I am sending you the
contents of the same to you. It says that the presentce of these three lines
(and the Cls= 'comm' and 'data' classes) is important, it means it's an ACM
device. The Driver=acm means the acm driver is used for the device. If you
see only Cls=ff(vend.) then you're out of luck, you have a device with
vendor specific-interface.
D: Ver= 1.00 Cls=02(comm.) Sub=00 Prot=00 MxPS= 8 #Cfgs =2
I : If#= 0 A;t= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=acm
D : If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=acm
while checking up the presence of these contents in my
/proc/bus/usb/devices, they goes like this :
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2

I: If#= 0 Alt= 1 #EPs= 3 Cls=02(comm.) Sub=80 Prot=ff Driver=(none)

E: Ad=81(I) Atr=13(Int.) MxPS= 4 Ivl= 1ms
E: Ad=04(O) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
E: Ad=85(I) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
I: If#= 0 Alt= 3 #EPs= 5 Cls=02(comm.) Sub=80 Prot=ff Driver=(none)
E: Ad=81(I) Atr=13(Int.) MxPS= 4 Ivl= 1ms
E: Ad=02(O) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
E: Ad=83(I) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
E: Ad=04(O) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
E: Ad=85(I) Atr=05(Isoc) MxPS= 128 Ivl= 1ms
And your goodself can see that Driver is none instead of acm. So I presume
that it is not linux compatible and I should drop the idea of expending my
energy unnecessarily to configure/installing it. However, what you say,
please revert.
