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. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
