Normally, the settings are used in Windows driver which fix the
config of the usb device. It is the known issue that the ecm mode
couldn't work with such settings. I don't sure the Samsung understand
this clearly, but our fae has notices them again to explain what
would happen. If you want to fix it, you should switch the config
to the vendor mode to let such vendor control transfers valid.
Therefore, I say it couldn't be fixed in ecm mode, and it is the
limitation of the hardware.

Although we provide the possibility of customization, we wouldn't
know which settings they would use completely. I think the tester
is asked by Samsung, so the better way is to get the device from
the Samsung.
