Using V-USB VID and PID

[praveen_khm]

Hi,

I have been experimenting with couple of V-USB implemented products like digistump and littlewire firmware. However, when I think of littlewire firmware which is again based on V-USB, uses PID and VID which belongs to adafruit industries. I tried changing the same to free ID's provided here, but it never seems to work. Sometimes, it fails to enumerate and other times, it says appropriate drivers not installed. I tried using inf-wizard.exe on windows to create drivers using the VID/PID provided here, but it does no good.

I am new to this. If someone can help me find out a way to change the VID/PID, would appreciate it. Thanks for all the help in advance and thanks to obdev for creating these free and open source stuff.

Nobody to answer this question, or is the question really difficult to answer? My first post and not sure if I need to wait for some more time on the forum for a response...

I read your post a day or so ago and didn't understand the problem with using the VID/PID pairs already assigned to the programs in question. What happens when you leave those alone? I suppose it's irrelevant to your question, but knowing the answer might make the problem seem more worthwhile to some people.

Right changing VID and PID have 0 effect on how the device preforms. As mentioned run the code untouched, if that gives you the same errors, it's not what you did If it seems to work without your changes then you are not changing the right values. Show us what you changed.
