Alby128 Posted May 26, 2012 Share Posted May 26, 2012 Hi, is it possible to create a DSDT patch that changes the product ID for an USB stick? I have a Pinnacle DVB tuner DVB-T PCTV 2000e and I wish to use it with Elgato EyeTV. Their software has full support for the PCTV 2001e which, AFAIK, is the same device that I own just with a different product ID. Device - VID - PID 2000e - 2304 - 022c 2001e - 2304 - 0229 I wish to use DSDT to change the Product ID of my 2000e device to the 2001e one, from 022c to 0229. Can I do that with a DSDT patch? And how? I have been looking for it on several forums, but, so far, I have only found patches that change IDs for internal components, not for external USB sticks. Thanks in advance, Alberto Link to comment Share on other sites More sharing options...
Funkoyote Posted May 26, 2012 Share Posted May 26, 2012 Maybe you can change the product ID into the info.plist of the EyeTV drivers. Link to comment Share on other sites More sharing options...

Maybe you can change the product ID into the info.plist of the EyeTV drivers. I tried hard to find the right plist into the eyetv.app package but with no luck, if you know where that is I would really appreciate your help...

Alby128 Posted June 19, 2012 Author Share Posted June 19, 2012 I managed to change the product ID of my TV USB receiver by editing the info.plist in AppleUSBMergeNub.kext. Unfortunately, even though EyeTV recognizes it as a 2001e, it still seems unable to find any TV channel. Also (but this was expected) it crashes a lot. Anyway, thanks for your help.
