very cool, but before I test it out (potentially breaking my usb
networking in the process), I have a couple of questions:
1. will this persist over a reboot, or will it revert back to being an
ethernet gadget when I reboot?
2. is the following sufficient to switch it back?
#!/bin/sh
rmmod g_file_storage
modprobe g_ether
ifup usb0
(assuming I replaced '/etc/init.d/networking stop' with 'ifdown usb0' as
recommended by Daniel)
3. can somebody point me to a resource for the g_file_storage module
where I can learn more about it? I did a couple of quick googles but
didn't see anything promising. specifically I'd like to know more about
the file parameter - I assume that in this scenario our "usb stick" is
using partition/device information from /dev/mmcblk0p1, and will be
partitioned in the same way as the SD card? what If I wanted to have my
home directory accessible in "usb stick" mode?
Thanks,
-Dale
