Sundriver not detected,

I have sun driver 2.06, i have used sundriver application v2.04 and v015, i have tried my Seagate 250gb HD formatted in both ntfs and fat32 (via mini tool partition wizzard).

When i connect power to the wii, the sundriver light is off, when connecting the usb to pc the light is red (half bright), then i press wii power button and sundriver light is red (full bright),

The sundriver program just says sun driver 'not connected yet' does anyone have any ideas or is it Faulty?

Ive spent hours trying to get this working but to no avail, I've tried to get the sun driver recognized on 2 different P.C's and in 2 different wii's, but nothing.

I would greatly apreciate any help, thanks
