[linux-dvb] Technisat AirStar 2 USB in kernel 2.6.21?

[Jan Wagner]

Hi,

I'm trying to get the AirStar 2 USB DVB-T receiver to work in Debian Etch. 
I'm using kernel 2.6.17 compiled for x86/ViaC7 with kernel config 
http://kurp.hut.fi/~jwagner/mini-itx/config-2.6.21 and i2c is built into 
the kernel.

The usb dvb-t receiver works just fine in WinXP, but in linux I get this 
error in dmesg:

   flexcop_usb: submitting urb 0 failed with -28.

and the receiver doesn't work, and /dev/dvb/adapter0 is not even created. 
Which is strange.

The error -28 perhaps is -ENOSPC, "no space left on device". At least per 
'df -h' there is plenty of free space on all mounts, so maybe this 
"space" is lacking somewhere else. (?)

And b2c2-flexcop also reports MAC address ff:ff:ff:ff:ff:ff, which I'm 
sure is wrong.

Any ideas?

Below is dmesg:

and as said, i2c_core etc is built-in so doesn't show up in lsmod. (but 
i2c works, I can use ddccontrol to read out LCD monitor settings over i2c, 
etc, so i2c should not be the problem here)

Many thanks!
