Once the module/firmware is loaded it's listed as two TeVii S660 cards.

Linux support

The s2-liplianin v4l branch includes support for the card.

Known Problems

• DVB-S is working
• DVB-S2 is problematic (lot's of TS discontinuity errors/packet loss)
  • maybe the early driver state causes the problem
    • testings with windows 7 32bit works with dvb-s2 and both channels, so the issue should be linux-driver related
  • tested on Astra 19.2E, diseque seemd not to be working
    • 11303 H, 8PSK 2/3 (ORF/Servus TV): Unwatchable / with Windows ok
    • 11362 H, 8PSK 2/3 (ARD/ZDF/ARTE): Unwatchable / with Windows ok
• we will get keyboard related input lags, this means after 15s the keyboard didn´t respond for 5s then it works again for 15s.
  • it depends on connected USB devices. Without any other usb devices and a ps2 keyboard you have no problem like this.
  • it´s eaqual using ssh or local keyboard
  • this problem is also only under Linux (testet with ubuntu Lucid and Maverick, Kernel 2.6.32 & 35)
