scsi_mod and sd_mod install after the installation of linux
 

I can't mount the usb flash drive. It might be I only configure the usb-storage module but not the scsi support when I installed the linux. I tried "insmod scis_mod" and "insmod sd_mod", but none works, --"no module by that name found." I also found "sg.o" in /lib/modules/2.4.18-bf2.4/kernel/drivers/scsi/ and installed it, but it seemed nothing happened.
Do I have to install the linux again? I won't to do that. I installed from net, and it took me more than 2 hours.

don't use insmod, that requires a direct reference to a module file. instead use modprobe, which will search your module tree for the right module. sd_mod is hardly unusual, and must be on there somewhere if you didn't roll your own kernel. try "modprobe sd_mod"

Thanks.

But it is still not working.
"can't locate module sd_mod"
I am using kernel 2.4.18.
