The 2.6.5 log seems to show a similar sort of error occurring, although at a different spot. It might be nice to see what's going on there and with 2.4, but to do that you'll have to rebuild the usb-storage module with debugging enabled. I doubt that GetMaxLUN confuses the device because all versions of usb-storage have used it, all the way back to 2.2. Windows uses it too, and also uses the same sort of INQUIRY command. Try looking at more logs and see if they all fail at the same place, i.e., during the INQUIRY command. Make sure you power off the device completely between attempts.
