My friend, I already posted the solution.
is nothing more than google, with the term linux thrown in, so you get the same great ability of google, precrafted towards linux.
We get many questions here, like yours, that are not asked out of a lack of linux knowledge, but are asked because the person asking didn't care to take the time to search for their own answer. I didn't weave a magic spell to find your solution, I searched at google for the terms WUSB54GC and ubuntu, and the link that had your solution (that I posted) was in the first 3 links.
I'm not suggesting that you're unintelligent, or unworthy, or any of that garbage. I was just ticked off that with zero effort I found your answer.
I'm sorry if I've offended you, that was not my purpose or my intention.
I would suggest going forward, that you use google's linux site. You can also help your searches by throwing in as many terms that apply as possible. As I said, ubuntu and WUSB54GC were all I needed to find your solution.
Peace and Regards,
