Ah, I found your later post - a phone.

Also found in your later post.
The reason why this is needed is that the device is advertising a non-zero
Device sub-class code.
That is, the line that says:
D: Ver= 1.10 Cls=02(comm.) Sub=02 Prot=00 MxPS= 8 #Cfgs= 1
should read
D: Ver= 1.10 Cls=02(comm.) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
Which means that your device is wrong, if I'm reading the CDC spec correctly.
There is no way you can fix this without contacting the manufacturer,
convincing them that they have stuffed up, and getting a firmware upgrade for
the phone...
I think that the extra entry above is probably the best solution (although not
the only solution). You might like to add a comment saying what the
vendor/product ID is, and why you had to add it, before sending this patch to
[EMAIL PROTECTED] (who is the maintainer of the acm code).
