Don't know if this will help or not...Since I have a PCI wireless card. But this is what I would try...
Do you have windows drivers for it?
Load them with ndiswrapper
First make sure your device is listed by typing lsusb this should show all your devices...
Next change directory to your folder with your windows USB driver...
You need the .inf file
Type ndiswrapper -i yourdriver.inf this installs your driver
To be sure it installed type ndiswrapper -l this should show your device present
Next type ndiswrapper -mi to write the module configuration
Type iwlist scanning this should show your wireless network
Now your ready to set-up your network
Type net-setup and the on screen guide should be easy to follow
you can check after you run this by typing ifconfig to see if you have been assigned an IPaddress
You may after this point need to click on your network manager and click on your wireless network the first time to get it to load up...
To get the autoload at boot .. You need to go into your /etc folder in there is a folder called module.autoload.d or something like that. You will need to be a super user in konsole or use your superuser file manager to edit the file that is your kernel type probably 2.6? Unless your on the beta...At the bottom of that file type ndiswrapper. This is so it loads that module at start-up...
Hope this helps you out. Sometimes you have to go through these steps more then once except for the last part writing in the file...But sometimes you need to go through these steps more then once for the network to be up at boot. Don't know why but sometimes it does that... After that it will boot everytime!Good Luck!
Or you may have to click on your network at reboot to get the connection up but it should start doing it on reboot everytime.
