Hi Sujith,
I seem to running into this same issue, mine is that the driver emits the
"Target unresponsive" error if the unit is powered-up with the TL-WN721N plugged
in already. I think my issue is that the USB subsytem event is not recieved by
the atk9k_htc driver, and therefore the hardware is not reset.

Has this ben fixed already? Can you give me the commit sha1 in wireless-testing?
I am using compat-wireless, so I am lagging master a bit.

If not, can you point me at where in the driver code the reset happens? Maybe I
can come up with a patch.
