Re: Write USB Device Driver entry not called

[eshwar]

I agree but the return value from the vfs_write should not be the -EBADF
(Bad File descriptor) it might be -EACCES (premission denied)... Correct me
if I am wrong...

this can be code in fs/read_write.c vfs_write()

 if (!(file->f_mode & FMODE_WRITE))
  return -EACCES;
