Add in usb serial pass through support, based on the current usb-linux.c.

Subject: [PATCH] USB serial device support
Add in a workaround to allow the usb serial devices to work with the
usb pass through mechanism. The ioctl() to request an alternate
interface will always return < 0 for a usb-serial device based on the
kernel driver. This means there is no alternate interface end point.
This was fully tested with a pl2303 usb serial device.
