Hi Experts,
I created a sample USB driver with character device access from user space.
I write a user space program to access the kernel driver write() function where I call usb_bulk_msg() to write in BULK OUT endpoint.
When I removed the USB in-between write transfer it crashes where the disconnect() is being invoked.

Hi Lyf,
Sorry to say it is not within the scope of our support on how to write a USB driver !
Suggest you had better refer to some books on linux driver.
