How to register a bulk device

How to register a bulk device

I'm very new to kernel programming. i created a simple USB driver by
reading greg's code
"http://www.cs.fsu.edu/~baker/devices/lxr/http/source/ldd-examples/usb/usb-skeleton.c"
My code is at http://kgcorner.som/code/simusb.c
As far as i thought, this code can read data and write data from and to
usb device. But when i attached my pendrive i saw dmesg trace i found
everything okay but unable to my my device in output of lsblk. As it's not
there i'm not able to mount it and hence unable to test my driver. Here's
dmesg trace ===========================================
