Hi Jayeeta,
I have a few questions on USB features.
1) MTP vs Mass Storage – Which one to use?
a. MTP and USB Mass Storage are mutually exclusive. Only one of them should be enabled at a time.
b. In Linaro ICS the Mass storage option is not present and there is only MTP in the UI.
Looks like MTP. Does anyone else have an opinion?
2) Does ECM have to be enabled?
What's ECM?
a. This requires changes to android specific files in the linux kernel. Since we have only one usb topic branch for both Android and Ubuntu is it possible to push changes to android specific files in the linux kernel?
b. There is already RNDIS class available. Do we need ECM? We can use either RNDIS or ECM.
3) USB tethering (RNDIS) option from UI
a. There is currently no tethering option from UI ( for neither USB/Bluetooth/Wifi ). Who should do the UI related changes. There is a launchpad bug – 887961
I think we may want to get a thread going on this and we can handle it as a feature request.
Thanks
Supriya
