Hi Mike, I tried on "Android Dev Phone 1" it does not seems to have support for gadgetfs. I can not see gadgetfs in /proc/filesystems also below are the list of devices it supports. I don't know which of them is usb.
# cat /proc/devices Character devices: 1 mem 4 /dev/vc/0 4 tty 5 /dev/tty 5 /dev/console 5 /dev/ptmx 7 vcs 10 misc 13 input 29 fb 90 mtd 108 ppp 128 ptm 136 pts 216 rfcomm 250 ttyMSM 251 adsp 252 msm_perf 253 oncrpc 254 smd Block devices: 7 loop 31 mtdblock 179 mmc How to put newly compiled kernel on the device and if something goes wrong how to revert it back. It would be great if you could point me to some URLs that gives this information.
