Auto enable dvb card after resume from sleep or hibernate

[fooladi]

some DVB Cards after resuming from sleep or hibernate are not recognized by windows. you may go to device manager and manually disable the enable them to start working.

 

by using this method you can automatically do this job. (I test this method in windows 7 64bit)

first go to this site and download DevManView (freeware).

for 32 bit:

http://www.nirsoft.net/utils/devmanview.zip

for 64 bit:

http://www.nirsoft.net/utils/devmanview-x64.zip

 

this tool can enable, disable or restart any device in GUI or Command Prompt in all windows versions (better than similar Microsoft command tool).

first run DevManView.exe

sort by: Device Type Code

you can see Your dvb card name in Net device. copy this name exactly as you see here. we need this for create command argument.

 

For example DVB device name is: "TechniSat DVB-PC TV Star PCI"

 

You can make ResetDVB.cmd Command file:

DevManView.exe /disable_enable "TechniSat DVB-PC TV Star PCI"

and create shortcut to Your desktop and reset your dvb card by just one click.

 

if you want automatically do this after resuming from sleep then you can use Task Scheduler in windows:

 

create a task which triggers by Workstation Unlock.(your system must locked and request password after resuming to use this trigger!)

its action is run DevManView.exe with arguments like this:

/disable_enable "TechniSat DVB-PC TV Star PCI"

Well done : a new way to practice a old trick (e.g. have a look here, but it was discovered well before...), perhaps more easy/convenient for newer OS or DVB newbies; but unfortunately both can't work out all tuner's faulty drivers or HW/SW "strange" combinations...

 

As an example I have two identical Terratec DVB-T Stick on two different HW PC, same OS (XP Pro) and in one there are no problem at all, it's stick is always ready to use after it resume from stand-by, ibernation or cold/warm reboot; in the second PC also is all OK but hibernation: on resume the two stick's instances are totally disappeared from HW list and therefore devcon or DevManView simply are unable to find them to disable/enable...; also a reset of the entire USB stack don't revive it: the only way is to phisically unplug/replug the stick to re-enable it... but luckily it only takes 1 or 2 second to watch TV again
