Dear All,
I have added some printk statements in scsi.c and hosts.c files to debug
USB Mass Storage Device. The SCSI module files exists in the following
directory.
/usr/src/kernels/linux-2.6.28/drivers/scsi
I am working in 2.6.28 version of the kernel in the CENTOS 5.2. I have
followed the following steps.
1) #make menuconfig
Enabled the SCSI Device Support as a module.
Device Drivers --> SCSI Device Support --> SCSI Device Support
2) Verified the CONFIG_SCSI is set to m or not in the .config file
CONFIG_SCSI=m (in the .config file) set
3) As I said above, added some printk statements in scsi.c and
hosts.c files (in almost all the functions)
4) #make M=drivers/scsi
I have executed the above command in
/usr/src/kernels/linux-2.6.28
5) I have seen that the following modules build perfectly.
scsi_mod.ko, sd_mod.ko and sr_mod.ko
6) I have copied all the modules into the following path.
/lib/modules/2.6.28/kernel/drivers/scsi
7) Then reboot the system
8) Then, I have inserted a thumb drive. Then I am NOT able to see
the debug statements that I added in the scsi.c and hosts.c files.
Note: I have done almost the same procedure for the usb/storage drivers
and I was able to see the debug messages there.
Could any one please tell me where I have done mistakes?
I had also tried the same in Fedora 10 and kernel version is 2.6.28 only
and I was not able to load scsi_mod as a module. When I opened
menuconfig and checked for SCSI Device Support, I was not able to change
it to module. The sign was "-*-". What does this sign signify. Can't I
load scsi as module with this sign.
Thanks in advance.
Regards,
Srinivas G
