Martijn,
I have a similar problem with a Toshiba DVD-R/RW. The device appears to
properly recognized in lsusb and in /proc/scsi/usb-storage-0/0. However,
the entry in /proc/scsi/scsi is strange and I am unable to mount /dev/sda
with the same error message. (In my case, it really is /dev/sda).
I forget where I found this, but someone suggested that some of the SCSI
and USB drivers should be statically compiled into the kernel. I have
a set of changes that generates a kernel that will allow me to mount my
DVD player. I am still testing to identify what is exactly required, I
am sure that I have unnecessary changes in this list. (I am using RedHat
8.0, kernel 2.4.18-14)
General --> NO Support for PCI Hotplug
SCSI --> STATIC SCSI Support
SCSI --> STATIC SCSI Disk Support
SCSI --> STATIC SCSI tape support
SCSI --> STATIC SCSI OnStream SC-x0 tape support
SCSI --> STATIC SCSI CD-ROM support
SCSI --> STATIC SCSI generic support
SCSI --> STATIC Probe all LUNs on each SCSI device
USB --> STATIC Support for USB
USB --> STATIC USB verbose debug messages
USB --> STATIC UHCI support
USB --> NO UHCI Alternate Driver support
USB --> STATIC USB Mass Storage Support
USB --> STATIC USB Mass Storage verbose debug
Let me know if this works. I plan to identify exactly which changes are
required, and then to try to find an explanation for what is different.
Ideally, I would be able to find a way to replicate this without a kernel
recompile, but I may just be dreaming.
Regards,
Aaron Sterr
