Hi Sascha,
this solution is not working for me. When compiling and installing the "media_build", it works
fine. Here in combination with a Digivox Duo Stick:
> Bus 002 Device 002: ID 1462:8801 Micro Star International
# lsmod | grep dvb
dvb_usb_af9015 21067 5
dvb_usb 22011 1 dvb_usb_af9015
dvb_core 67624 1 dvb_usb
rc_core 17813 12
dvb_usb_af9015,ir_lirc_codec,ir_sony_decoder,ir_jvc_decoder,ir_rc6_decoder,dvb_usb,ir_rc5_decoder,rc_imon_pad,ir_nec_decoder,imon
i2c_core 18989 6 mxl5005s,af9013,nvidia,dvb_usb_af9015,dvb_usb,i2c_nforce2
usbcore 99058 11
lirc_imon,dvb_usb_af9015,dvb_usb,usbhid,imon,usb_storage,uas,ohci_hcd,ehci_hcd
One very strange behavior is, when theres no dvb-adapter at all, the system loads dvb_ttpci, but
no such card is installed, nor gets any /dev/dvb/ created or anything logged in dmsg:
# lsmod | grep dvb
dvb_ttpci 71007 0
dvb_core 67624 1 dvb_ttpci
saa7146_vv 39558 1 dvb_ttpci
saa7146 17148 2 dvb_ttpci,saa7146_vv
ttpci_eeprom 12344 1 dvb_ttpci
i2c_core 18989 5 dvb_ttpci,videodev,ttpci_eeprom,nvidia,i2c_nforce2
Building and installing "new_build" as suggested, ends up with
# dmesg | grep dvb

>From there on, those errors appear attaching any dvb-usb adapter i have, there seem to be a
problem. The rtl2831u adapter identifies as following and is labeled "Digitus DA-70781-B/A1" and
worked fine with Jan Hoogenraads driver under 2.6.32.
