Wow.. so I just now downloaded the "driver"
(not really a "driver", by the way) package from
http://home.eeti.com.tw/LinuxDriverDownload.html to have a look.
It's HORRID!! The instructions given are incredibly complex for something so simple. Like they were translated from one language to another, to a third, and finally to English.
And even allowing for
Lost In Translation effects, they're just so bizarre in what they want one to do. This isn't Linux, this is just a company with clueless developers or doc writers.
I don't see why they have you reconfiguring the kernel in the first place, since their package doesn't actually include a kernel driver or code -- it appears to just use stuff that is already built-into your kernel.
My sympathies to you.. Good Luck!
