Hi Sonasath,
Check by executing the test cases with only the mass storage function
enabled from kernel configuration.
Menuconfig -> Device Drivers --> USB Support --> USB Gadget Support -->
and select only Android gadget mass storage function.
If it suceeds please refer the below discussion link:-

(5.2.3) Devices must consider the CBW meaningful if no reserved bits
are set, the LUN number indicates a LUN supported by the device,
bCBWCBLength is in the range of 1 through 16, and the length and
content of the CBWCB field are appropriate to the SubClass.
