No, i don't see that (Set-Config request with a config value of 0) >> g_file_storage gadget: ep0-setup, length 8: >> 00000000: 80 08 00 00 00 00 01 00 >> g_file_storage gadget: get configuration >> g_file_storage gadget: ep0-in, length 1: >> 00000000: 01 > > This is the correct response following the request above. > > You can test the gadget's behavior with a Linux host.

When i use "echo 0 > /sys/bus/usb/devices/.../bConfigurationValue", there is no activity in gadget and UDC driver, and the gadget disappear from Linux host. If i use "echo 1 > /sys/bus/usb/devices/.../bConfigurationValue", the gadget is re-enumerated and re-appear in Linux host. I also observe in gadget driver, there is only one config descriptor with bConfigurationValue of 1. Is bConfigurationValue of 0 meant to disble the device?
