Hi,
The file transfer from my android OTG device(Uses MTP) to host is
partial. Sometimes it hangs. Sometimes the size of the file
transferred is zero. Can someone suggest me how to debug this issue? I
cannot differentiate this faulty transaction with the working case
when tried to use USB protocol analyzer. Also what is the significance
of TX_REQ_MAX macro in f_mtp.c? What difference will it makes if I set
to 2 instead of its default value 4?
Regards,
Vishwanath
