I'm trying to use the DIFxAPI to install a msvad-class device (software only), but I can't figure out how to make it work. With an added [DefaultInstall] section in the .inf file I could make the test application install the driver files (.inf+.sys), BUT it doesn't seem to start the device! I.e. I cannot see the device in control panel. During development, I use devcon for installation/uninstallation, and I get the same behavior there (almost), namely that devcon install <inf-file> <hwID> installs the driver, but I need to do devcon enable <hwID> to actually startup the device (it is always in stopped mode after install). Any ideas here, cause I'm loosing hair over this. The little I have left that is...
