moinmoin,

while playing with g_file_storage i noticed some things .. i did the  
following:

dvalin:~# ifconfig usb0 down
dvalin:~# rmmod cdc_ether
dvalin:~# rmmod g_ether
dvalin:~# modprobe g_file_storage file=penDrive.disk
# which is an image i created with explanations from http://www.linux- 
usb.org/gadget/file_storage.html

then my mac (pb-g4) told me he found a new device but did not show it  
in Disk Utility.app
while my debian-running clamshell-ibook recognizes sda1

now i wanted to remove the module and typed:
dvalin:~# rmmod g_file_storage

the shell i used for this freezed (no prompt occured) while the rest  
of the system is stil responsive

here the dmesg-output:

usbcore: deregistering interface driver cdc_ether

dvalin:~# uname -a

what is happening there?
