[linux-dvb] AVermedia DVB-T 771: mt352_read_register: readreg error (reg=127, ret==-5)

[Miguel Yarza]

I have an AVermedia DVB-T 771 and have sucessfully installed it in one 
computer:
Shuttle SN41G2 k7 nforce2 chipset
Kernel: debian 2.6.10-1-k7

modprobe dvb-core
modprobe dvb-bt8xx

and the card works flawlessly, I can watch TV with no problem.

Then I put the card in another computer with the same installation and 
kernel:
Motherboard: K7 ASUS A7N8X-E DELUXE  (k7 nforce2 chipset too)
Kernel: same debian 2.6.10-1-k7

I get the following message:

dvb-bt8xx: A frontend driver was not found for device 109e/0878 
subsystem 1461/0771

I've got cvs as of 2005-03-02 and loading the modules with debug options 
I get (complete dmesg follows):

DVB: registering new adapter (bttv0).
bt-i2c: ERR: -5
mt352_read_register: readreg error (reg=127, ret==-5)
dvb-bt8xx: A frontend driver was not found for device 109e/0878 
subsystem 1461/0771

I previously posted this problem but with recent changes in mt352 now 
the error prints the register 127 and maybe this could be a clue :)

Thanks
