Title: inf file
Post by: NovoJf on July 22, 2010, 05:39:09 pm

Hi,

I modified the inf file for my USB application. I already install the driver so all old informations appear in the register (REGEDIT). In the inf file, I changed the PID. I uninstalled the driver in the peripheral manager and tried to reinstall this driver with the new PID. (To be sure, I changed the version number). I can not install the new driver because the PC always reinstall the same driver even the inf file has been modified.

How can I change the inf file or what can I do for the PC change information in the PC register?

Regards,

JF

Recent Windows editions prefer digitally signed drivers (including INF files). See:
