In answer to these questions...
"vend/prod 0x403/0xfc82" refers to the USB identification numbers built in
to the device. 0x0403 is the Vendor ID and 0xfc82 is the Product ID.
There are tables of vendor/product numbers available on the web, if you
want to look something up. Of course there's no need to do that here; you
know that the numbers refer to your phone/cradle. You can also see the ID
numbers in /proc/bus/usb/devices while the device is connected to your
computer.
The "not claimed by any active driver" part means that none of the drivers
that happened to be loaded in the kernel at the time you connected the
device were able to control it. ("active" simply means "currently
loaded".) This is normal; generally the hotplug system will be invoked to
find the appropriate driver and load it automatically. If your device is
working then you don't have to worry about this message. And you don't
have to worry about it being supported -- since clearly it is already
supported in the kernel you're using.
