Hello all, I have a query regarding the android usb gadget driver. I am using the android kernel 2.6.32 with omap3630 based board. In the USB android gadget driver, the value of "bInterval" for high speed BULK OUT endpoint descriptor for mass storage interface is set to "1" (f_mass_storage.c) and "bInterval" for high speed BULK out endpoint descriptor for ADB interface gets set to "0" by default. (f_adb.c) According to USB specs, the host ignores this value (bInterval) for full speed bulk and high speed bulk in endpoints. For bulk OUT endpoints, this value indicates the endpoints maximum NAK rate.
My query is why is the value of "bInterval" set to 1 for mass storage interface and 0 for ADB interface. Is there any specific reason for doing the same? Thanks for your time.
