The problem is usbdev5.5_ep02 is not labeled correctly.  Is this a real
device?  What kind of device is is?

Happens every time I boot.  Appears to depend on the usb devices I
have connected at the time (I have 2 'docks' for my laptop, so the USB
setup is not the same).

In this case, 'lsusb' says:
Bus 005 Device 005: ID 04b8:010a Seiko Epson Corp. Perfection 1640SU
Bus 005 Device 004: ID 0461:4d03 Primax Electronics, Ltd Kensington
Mouse-in-a-box
Bus 005 Device 002: ID 04b3:4484 IBM Corp.
Bus 005 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 003 Device 003: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Bus 003 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000

So I'm guessing usbdev5.5_ep* is pointing at this.
