Thanks for clear explanation. Could you please let me know where does
host_controller will be present is it in USB device or USB core part
of kernel.

Actually my issue is that we ported Gobinet driver from open source to
support one dongle. After porting, it is working fine on little endian
host (linux-2.6.31 kernel). We have added some changes in driver code
o support it for big endian hosts. After adding the changes with the
help of le16_to_cpu () function dongle is working in one of our big
endian hosts (which has linux-3.10.20), but facing corrupted packet
issue in other bigendian supported host (linux-2.6.32). Could you
please help in providing some pointers here
Sounds like you have a bug in your code.  Did you expect me to make a
more precise guess?
