I have a problem uploading files in this forum here is a link you can directly download the screenshots http://www.2shared.com/file/Mcwx0OEm/driver.html
yesterday the device were listed under Ports (COM & LPT) but now it changed like what you see in the screenshots!!
I am posting this problem everywhere I even raise a case but till now i found nothing
here is a link Mr.Dana think is useful doesn't work with me but it may work with you
To upload you can only do one file at a time, so zip or rar them
if multiple files.
Use IE or Firefox, Chrome seems to have problems.
I have been finally able install my driver.I think there was some problem with the board.
Thank you for help.
