Hi,
I guess I'm missing something stupid here. I've got a AVerTV Hybrid Volar HX usb stick and I can't get it to work. Following some guides I noticed that udev wasn't creating /dev/dvb/* device files when I plugged the stick in but rather files like
Code:
/dev/usbdev7.5_ep00
/dev/usbdev7.5_ep01
/dev/usbdev7.5_ep81
/dev/usbdev7.5_ep82


Following /usr/src/linux/Documentation/dvb/udev.txt I created files /etc/udev/rules.d/dvb.rules and /etc/udev/scripts/dvb.sh:
dvb.rules:
Code:

#KERNEL=="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
ATTR{idVendor}=="07ca", ATTR{idProduct}=="a827", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c", GROUP="video"

The commented-out line is was the first attempt, after which I tried to write my own rule with no luck. I'm not sure when exactly was the first rule meant to match as it seemed to execute my logging rule
Code:
KERNEL=="*", PROGRAM="/root/log.sh"
after a module with a dvb* prefix had been inserted into the kernel.

dvb.sh:
Code:

#!/bin/sh
echo `date` $1 >> /tmp/udev.txt
/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'

The echo here is a notification that the rule key matches and the script is executed. It's not.

I can't see why the recommended rule nor my own rule wouldn't match. The device is correctly detected by the kernel when it's plugged in as dmesg indicates:
Code:
usb usb7: usb resume
ehci_hcd 0000:00:1d.7: resume root hub

usb 7-2: Product: AVerTV
usb 7-2: Manufacturer: AVerMedia
usb 7-2: SerialNumber: 301357900268


I've even tried to pass the udev-created files (/dev/usbdev7.X-epYZ) to mplayer but with no luck there either.
Code:

foxicatko /etc/udev $ mplayer -tv driver=v4l2:device=/dev/usbdev7.7_ep00 tv://
MPlayer SVN-r28450-4.1.2 (C) 2000-2009 MPlayer Team
CPU: Intel(R) Core(TM)2 Duo CPU     T7250  @ 2.00GHz (Family: 6, Model: 15, Stepping: 13)
Playing tv://
Detected TV file format!
Selected driver: v4l2
 name: Video 4 Linux 2 input
 author: Martin Olschewski <olschewski@zpr.uni-koeln.de>
 comment: first try, more to come ;-)
v4l2: unable to open '/dev/usbdev7.7_ep00': Permission denied
v4l2: ioctl set mute failed: Bad file descriptor
v4l2: 0 frames successfully processed, 0 frames dropped.


Ending... (End of file)

I suppose it's usbdev7.7-* here because i've tried plugging the stick in and out to get output for this post.

I'll happily post more info when requested.

Thanks for all help.

I've got the 0.25beta from this site: http://www.avermedia.com/avertv/Product/ProductDetail.aspx?Id=31&tab=APDriver
I've tried it with 0.21beta to avail either. Driver installation works beautifully until an audio test upon which it tries to tune to a TV channel and play render sound through my soundcard but fails with "No tuner devices found".

Googling around makes me feel like I'm the only one with this problem, since other's problems have been solved with previous driver releases which imo means that the problem is somewhere between the chair and udev or .config. :-/
