Again, an old nasty problem is back in FC2 test 3: using the latest linux-2.6.5-1.327, when I attach an IOMEGA ZIP CD (USB) (RW) unity to USB port, usb_storage recons it and registers correcty (both at /sys and /proc/...), device /dev/scd0 is active (I can mount, umount and read CDs) and I got a message indicating that it was registered as sr0 (althought I cannot have access do /dev/sr0). But the device is not reconned by sg.ko (is is not registered).

(althought I cannot have access do /dev/sr0). But the device is not reconned by sg.ko (is is not registered). The first consequence of this behaviour is that I cannot record anything using the unity.
