unable to mount ub.ko

Hi,

I don't know whether this is the right list to post my query or not, but I am really struggling alot to mount ub.ko. Can anyone comment on the below given steps.....

1) I compiled ub.c, and obtained ub.ko in GNU Linux 2.6.9-5
2) I created a node in /dev but couldn't mount it as I had no root permissions
3) Tried to compile in Fedora2, it gave warnings for "usb_kill_urb" and "msleep"(which I didn't see in GNU LINUX)
4) I ignored those warning and tried to insmod ub.ko, and then it gave the following errors
i) Unknown symbol for "usb_kill_urb" also for "msleep"
5) I commented "ub_probe_clear_stall" and "msleep", and then insmod was successful
6) Then I did "mknod ub b 180 1", it created a node but when I tried to mount it gave error saying that "ub is not a valid block device"
7) Here I tried by passing "UB_MAJOR = 0" and got major number 251. Again node was created but when I tried to mount, I got the same error. Please look into the below given /var/log/messages for the same.....

May 11 22:25:45 localhost kernel: ub_init--MAJOR:251
May 11 22:25:45 localhost kernel: usbcore: registered new driver ub

Note: I gave a printk to see "ub_init--MAJOR"

I renamed the same file as stdr_2/stdr_3 and tried the same. Please look into the below given /var/log/messages for the same....

May I know why I did fail to mount the node? Do I need to block usb-stroage driver to test ub.c?

Thank you,
