Actually, it is/was a SCSI problem. The short version being that it is/was easier to hotplug an entire HBA rather than an individual device. That is being changed in 2.5 right now. usb-storage used an HBA-per-device, while SBP2 uses a single HBA. Of course, all this is being changed right now in 2.5.x Matt --=20 Matthew Dharm Home: mdharm-usb@one-eyed-alien.= net=20 Maintainer, Linux USB Mass Storage Driver It's monday.
