I have a board with USB slave 1.1, and Linux installed on it.

I have connected it with a PC through a USB cable.

And I want to make the PC "know" the device?

on the board(the kernel is 2.6.11):

1. start Linux

2. dd bs=1M count=8 if=/dev/zero /root/data (FAT32)

3. modprobe g_file_storage file=/root/data

HERE IS THE ERROR MESSAGE:
*****************************************
Using /lib/modules/2.6.11-XSBase27x/kernel/drivers/usb/gadget/g_file_storage.ko
insmod: cannot insert `/lib/modules/2.6.11-XSBase27x/kernel/drivers/usb/gadget/g
_file_storage.ko': Device or resource busy (-1): Device or resource busy
modprobe: failed to load module g_file_storage
*****************************************

which device is busy?

Or
what should I do before I "modprobe g_file_storage..."?
