The change in Device number from 024 to 025 means that it reset itself
somehow. Only bcharge does this normally, but since it looks like your udev
rules don't match for 8004, then bcharge shouldn't be running.
Perhaps the Blackberry itself resets when the usb_storage module tries to
make use of the mass storage mode? Does this product ID change happen
if you comment out all udev rules that call bcharge?
There is nothing in Barry that checks for mass storage endpoints. It
doesn't really care if they are there are not. Bcharge merely tries
to reset the device into a mode that charges properly at 500mA, and
exposes the database USB endpoints, preferrably with both database and
Mass Storage endpoints available. Mass storage is completely up to
the kernel.

It should be safe to duplicate the rules with different product IDs.
This is what the existing Barry rules do, and if possible, I'd like
to update them for the 9630, if you can help me test, since I don't have
such a device.
Once you have something that works, a patch against the existing rules
would be excellent.
Thanks,
