[linux-dvb] help with Twinhan VisionPlus 1020A

[Luis Alberto Zarrabeitia]

Hi. Thanks for your quick reply, however, the problem is not solved yet.

I did a modprobe dvb_bt8xx, and the module loaded.
I didn't have the devices in /dev (maybe because I use udev?), I
created them manually.

However, the dvb-apps/utils/scan/dvbscan application (scan?) reports this:
--------------------
# util/scan/scan util/scan/dvb-s/Astra-19.2E
scanning util/scan/dvb-s/Astra-19.2E

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:1882: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 19 No
such device
--------------------
(frontend0 is c 212 3). On an italian forum is suggested that I should
load more modules, but I understand zero italian, so I couldn't
understand the message (other than a modprobe command).

I have loaded:
--------------------
# lsmod | grep dvb

dvb_bt8xx              10436  0
dvb_core               83848  1 dvb_bt8xx
nxt6000                 7524  1 dvb_bt8xx
mt352                   5764  1 dvb_bt8xx
dst                    13320  1 dvb_bt8xx

sp887x                  8196  1 dvb_bt8xx
bttv                  155152  2 dvb_bt8xx,bt878
firmware_class         10144  3 dvb_bt8xx,sp887x,bttv
i2c_core               22736  10
mt312,dvb_bt8xx,nxt6000,mt352,dst,sp887x,tuner,bttv,i2c_algo_bit,i2c_i801
---------------------

I forgot to say it on my previous post, I'm using a 2.6.10-1-686
kernel from Debian Sarge (my last update was right before sarge was
frozen, but I cannot upgrade for a while).

Regards,
                   Luis.
