No, where can I see that one?

I tried the attached patch which I found on the usb list, but it didn't
work, the cdrom was still always found, and it was
connected/disconnected permanently. Currently I was at:

...
Oct 30 22:20:32 mithrandir kernel: usb 2-2: new full speed USB device using uhci_hcd and address 13
Oct 30 22:20:32 mithrandir kernel: usb 2-2: configuration #1 chosen from 1 choice
Oct 30 22:20:32 mithrandir kernel: usb-storage: probe of 2-2:1.0 failed with error -5
Oct 30 22:20:32 mithrandir kernel: option 2-2:1.0: GSM modem (1-port) converter detected
Oct 30 22:20:32 mithrandir kernel: usb 2-2: GSM modem (1-port) converter now attached to ttyUSB0
Oct 30 22:20:32 mithrandir kernel: usb-storage: probe of 2-2:1.1 failed with error -5
Oct 30 22:20:32 mithrandir kernel: option 2-2:1.1: GSM modem (1-port) converter detected
Oct 30 22:20:32 mithrandir kernel: usb 2-2: GSM modem (1-port) converter now attached to ttyUSB1
Oct 30 22:20:32 mithrandir kernel: scsi35 : SCSI emulation for USB Mass Storage devices

Note the SCSI35 !!!

So is there any other patch I can try?

Best wishes

Norbert
