Disable USB mass storage

[ka...@silvertejp.nu]

When I connect the BeagleBone Black to my PC it shows up as as USB mass storage device. Is there some way that I can disable this function? I want to use Ethernet over USB but I don't want it to act as a storage device.

In Angstrom:

modify:

/usr/bin/g-ether-load.sh

In my Debian I did
sudo nano  /opt/scripts/boot/am335x_evm.sh

You could comment out line shown below, but it would disable Ethernet.

#modprobe g_multi file=${gadget_partition} cdrom=0 stall=0 removable=1 nofua=1 iSerialNumber=${SERIAL_NUMBER} iManufacturer=Circuitco  iProduct=BeagleBone${BLACK} host_addr=${cpsw_1_mac}


add this to have Ethernet

modprobe g_ether host_addr=${cpsw_1_mac}
