Hi all,
Has anyone ever installed Linux from a USB CDROM?
I have a machine that supports USB CDROM boot which I have duly selected.
The machine boots OK from the USB CDROM but then fails to recognise
itself (using RedHat 7.2 install disks). It seems to be registering the
usb device ok and installs the scsi emulator, but then fails to
recognise the very media from which it booted!!
Messages I get are:
Initialising USB mass storage driver....
usb.c : registered new driver usb-storage
scsi0 : SCSI emulation for USB mass storage devices
........ a 15-20 second delay ........
scsi : device set offline - not ready or command retry failed after bus
reset : host 0 channel 0 id 0 lun 0
WARNING: USB mass storage data integrity not assured
USB mass storage device found at 2
USB mass storage support registered
The USB device is a ScanLogic USBIDE.
cat /proc/scsi/usb-storage-0/0 shows me:

cat /proc/bus/usb/devices gives me:

Any ideas anyone?
