Record successful, but leave a 0 kB file

Some of the hauppauge cards have this problem of not able to see the signal (even when there isn't any problem with the signal) after a bootup or reboot.
This is not the problem of NPVR cos even with other TV softwares, it see no signal too, and have to reboot PC till it see the signal again.

Is it not possible to reset the Hauppauge card without rebooting? And if so.. could this be done by NPVR if it detects that it has a problem with the signal?

You could try the Device Stop, Start, Restart (if it exists) command line command. I used to do this with a tuner that would disappear after the computer came out of sleep. Worked some of the time. I ran a batch file with these commands started by Task Scheduler and triggered by wake from sleep.

I don't have my info available now as I'm away.

I found it on the net, try searching on the Device Start command. Takes some fiddling, but it did work, at least the batch file always ran. I directed the output to a log file so I could see that it worked.

I used DEVCON with some success in the past to get the status and if necessary restart a device when booting. http://support.microsoft.com/kb/311272
I started off just emailing myself the results. Here is a failure example.

I used DEVCON with some success

Hi martin, do you hapen to have the DEVCON script example to run that?
When did you run it, can you run it say 5mins before a recording, automagically, via one of the batch files in scripts?

@jksmurf

I can get you my script but not until late Thursday US time.

I'll try to find it in one of my backup archives. My problem was a USB DVB-T tuner that didn't give data when waking from standby about once a month. I ran it from a wake from standby script as once the system was up and working I didn't seem to have the problem.

I remember now that the snag with my problem was that devcon only showed the failure AFTER a failed recording. When it came out of standby it showed as OK and only showed a failure once a recording had failed. So it wasn't a 100% sucess. Now I do a full power off and reboot once a week and I don't seem to get the problem as much, if at all.

This wish would be a nice solution for that.

You could now already use such a USB-relay to powercycle the device once a day.

OK thanks. I can still try it in wakeup.bat. The wiki says "Run after the ... resumes from sleep, before any recordings are started. No arguments. "
Sounds perfect for my wife.

Here's my script, a sample of the log file, and the devcon help file. I ran this from Task Scheduler on wake. I expect wakeup.bat would be easier as it was a pain to figure out how to do it in Task Scheduler.

You'll have to go into Device Manager to find the ID (PCI_VEN etc) of your tuner. Devcon allows wild cards so you only need enough characters to uniquely ID the device. See the batch file.

Thanks Mike, much appreciated.

Oddly it demands a system restart, I'll have to see why this is. Anyone got any tips to work this out?

Code:

echo off
echo %date% %time%
devcon status "USB\VID_2040&PID_5020&REV_0000"
devcon restart "USB\VID_2040&PID_5020&REV_0000"
:Reports the source of the wakeup
powercfg -lastwake

Code:

C:\Users\Kristian\Desktop\devcon>echo off
