Hi Shlomo,
We are working on DM3730 EVM and want to enable OTG.
We changed in the kenel .
We tried insmod g_mass_storage.ko file=/dev/sda stall=0 removable=1
and got following log:
root@dm3730-am3715-evm:/# insmod g_mass_storage.ko file=/dev/sda stall=0 removab

Still EVM is not getting detected on PC side
We connected the otg port of DM3730 to the USB port of PC through USB cable.
Also I have tried to connect the pendrive to the OTG port of EVM, that is also not getting detected.
Please suggest us to solve this issue.
Regards
Vidya
