Hi Deepak,

I do have one device for the following drivers:

vt6656
vt6655
r8188eu
r8192e_pci
r8712u

Minimum test is to measure the transfer speed and see if that is as 
expected.

When I doubt that the changed code is used I use ftrace to see if the 
code is used. But of course I do not test every possibility.

I hope you have the money to be able to buy hardware. Without it is not fun.

I would choose r8188eu (USB) or r8192e_pci.

Bye Philipp
