[09/12] USB: remove broken usb-serial num_endpoints check

[Greg KH]

2.6.24-stable review patch.  If anyone has any objections, please let us
know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxx>

commit: 07c3b1a1001614442c665570942a3107a722c314

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
code are just wrong, there are too many different devices out there with
different numbers of endpoints.  We need to just be sticking with the
device ids instead of trying to catch this kind of thing.  It broke too
many different devices.

This fixes a large number of usb-serial devices to get them working
properly again.
