Lots of USB hardware appears as one device id when powered on, then when the firmware is loaded turns into something else that becomes relevant to the user. So on powerup your wireless card goes 'I've no idea what I am, feed me firmware for this id" when it gets the firmware it disconnects, reconnects and says "I am a USB wireless card with this id" When you suspend the power gets killed so the device loses its firmware and goes back to being a firmware requesting thing on resume. Worse still - you don't easily know if the device is in fact new and was added while suspended, or was always there. So for those devices you do need to load the firmware into them automatically after the resume to work out what they are and get the MAC to see if its the same wireless card or not.
