I revised due to concerns as of Nov 11, 2011 11am pst.
Your question mixes up a couple of reasons why it doesn't fit the site.
You're not entirely clear about what you mean in extending a USB over wireless. Is that a data transfer from the stick to another port? Adding more reach to the signal?
Being unclear puts your question in a vague state, enough for votes to close as "not a real question" (NARQ).
But then it tries to clarify itself in terms of a laundry list of features. This makes it a shopping question and off topic.
Could have gone either way, but the tally of final close votes sided with NARQ.
