Did you tell the pl2303 driver to bind to this device, or did it do it on its own?

Can you try out the 2.6.23-rc1 kernel to see if that solves this problem?

>Did you tell the pl2303 driver to bind to this device, or did it do it on its

what i see / recognize it?


full dmesg from 2.6.23rc1:
strange in dmesg at start it write a ver 2.6.22.1 - i download a patch from 
kernel org, copy it to /usr/src/2.6.22.1/, and bzcat patch23rc1.bz2 | 
patch -p1
patchink like ok ( no errors messaages), then i run make menuconfig, and 
compile all - again, without errors.
btw, first bug:unable to handle... in dmesg is _before_ a insert huawei 
card...?
second bug: unable to handle is after a insert huawei card....

today i compile kernel 2.6.18.4 and all works great! in link, who i gives ( from lists.debian.org ), also says,a problem with huawei in entered after kernel number 2.6.18.4....

Any update with this problem please?
Thanks.

Problem is in files pl2303.h and option.c, because both have a bindings for this modem. And kernel try to use both. Someone should to delete the product and vendor from one of them.
