i am lost with my TT Connect S2-3600. It used to work, but after a
teporary switch to kernel 2.6.30 i can't get it up anymore.

I am back on kernel (SuSE) and the S2-Liplianin driver
package. All modules built fine and are installed correctly. A
FullFeatured card that is also there, works without problems. 

When i connect the USB box, it get the following error:

usb 3-5: new high speed USB device using ehci_hcd and address 2
