I must thank your for all the help you provided.
I compiled kernel 2.4.24 and every thing works so well. All my problem are gone.
Thanks so much for your time and kindness.

I checked up the specification and this is an ACM device
I: If#= 1 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=05 Driver=(none) E: Ad=81(I) Atr=03(Int.) MxPS= 64 Ivl=1ms I: If#= 2 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=serial E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
Interface 1: Cls: Communication Interface Class Sub: Abstract Control Model Prot: Reserved (future use)
Interface 2: Cls: Data Interface Class Sub: Not used Prot: No class specific protocol required
The extra interface 0 seems not be defined in my version of the spec
I: If#= 0 Alt= 0 #EPs= 0 Cls=02(comm.) Sub=08 Prot=01 Driver=(none)
Interface 0: Cls: Communication Interface Class Sub: Reserved (future use)

So you only need a serial interface to the phone? The OBEX interfaces are of no interest for you?
What kernel do you have tested?
