Hello,
I hope I'm posting this in the right place. I have looked a lot for the
solution to this, but have not found anything - I'm sorry if I'm
posting something very obvious or already answered. I've just installed
kernel version 2.6.13 and am having problems with the scsi support for
mass storage devices. I have compiled all this into the kernel:
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_USB=y
CONFIG_USB_STORAGE=y
well - I've basically tried compiling just about everything in.
I'm trying to attach a digital camera via usb (not usb2 - hence uhci
here). The output for /proc/bus/usb/devices shows up the camera, and
hotplug loads libgphoto2, but in the messages log there is nothing
saying SCSI emulation for mass storage devices. I notice also that in
my udev.rules file there is nothing to create the sda* devices although
I was hoping to see it mapped to sda1 or something. Output of
/var/log/syslog and /proc/bus/usb/devices below as well as the only usb
part of my udev.rules file.
proc/sys/kernel/hotplug is pointing at udevsend and this is doing
something right as hotplug is managing to load the libgphoto2 library
and various directories get created in the sys/bus/usb/devices
directory. I'd really like to know what I'm doing wrong and why udev
isn't creating a device, and more importantly why the SCSI emulation
never appears in the /var/log/syslog. Should I just ignore this and
write a new udev rule.
Many thanks for any help you can give me
Ewen
(P.S. I've just
noticed an error message on boot-up saying ide-detect isn't installed,
and xcdroast isn't detecting any drives, which I think could be
related.)
