RE: Prof DVB-S2 USB device

Hi Oliver,

   I migrated to Ubuntu 13.04 on desktop and tried. It worked ! 
   It uses linux kernel 3.8.0. If I use this version of linux kernel or greater on Pandaboard, it may work on Pandaboard also.

Regards,
Kishore.

 From a quick glance I noticed you are missing the CONFIG_USB_EHCI_HCD (EHCI Host controller) it appears you don't have a USB host controller enabled at all? But i'm not sure what kind of USB controller omap4 has.
