[usbserial] device 0421:069a is supported, in fact.

Dear "linux-usb" mailing list people,

I was directed here by the email-bot of Greg Kroah-Hartman.

First I was contactim him directly, since at [1] it is written that
things regarding the `usbserial` driver should be directed to him,
which in turn I was getting from a question on where-to-address-this
which I asked here [2].


Here the issue I want to address:


I have a device which is ignored by any in-kernel driver, but when I
tell `usbserial` manually to drive that device (via
`modprobe usbserial vendor=0x0421 product=0x069a`), it provides two
serial ports where useful things can be made via the second.

It is a Nokia 130 mobile phone, and it provides an "AT"-style serial
interface where things like address book synchronisation can be made.

It has the following vendor:product number 0421:069a.

So I suggest to you to add that device as a supported device to
`usbserial`, so that hotplug works.

In `lsusb` it shows up as
`Nokia Mobile Phones 130 [RM-1035] (Charging only)`, so the string
`(Charging only)` should be removed then, too.

(The phone itself has two USB modes: "Memory card" (which will make it
behave as mass storage with access to the microSD-card) and a mode
which is called in the phone's menu as "Charging only", which is the
mode interesting here and which in fact is more than "carging only").


I have also made a Linux bugtracker issue out of this [3], but my
experience is that issues posted there are sometimes very unreliably
noticed (depending on the subsystem, some parts of the bugtracker seem
to not get attention at all). That's why I followed the suggestion in
[1] instead at first. I am still confused about what is the correct way
to give this information to the people able to deal with it properly.
