Subject: usblp: Add serial number to device ID
From: Dirk Eibach <[EMAIL PROTECTED]>
I noticed that some USB-printers, e.g. Canon PIXMA iP3000 don't add their
serial number to the IEEE-1284 device ID string as expected by userspace
apps like cups. Because of this, connecting multiple printers of the same
type to a system does not work properly.
This patch adds the usb serial number to the device ID if it is left
out by the printer.
