Hi Hans,

Thanks for your reply.
I had lucky here, changing the external disk to other usb port, but
lsusb shows me
that only change is the mouse (I change the mouse port with the external hd),
by the way this usb-ide adapter has power supply by usb too.

Strange that usb-ide adapter get the same ugen ports... but is working now!
If you need someone to test any modifications I have some time here.

Thanks a lot,
