USB Driver
●
Two types of USB drivers
While the USB driver that can be used in iR series is only the USB driver designed exclusively
for MEAP application (hereinafter referred to as “MEAP driver”), not only MEAP driver but
also USB system driver (hereinafter referred to as “system driver”) can be used in iR-ADV
series.
System driver and MEAP driver cannot be used together. When either of them is used, the
other driver cannot be used.
●
USB driver setting (iR-ADV series)
System driver is active by default in iR-ADV series.
The driver can be changed in Settings/Registration (user mode).
Usually, It is not necessary to change the setting because it is specified in the MEAP
application side.
Only in the case of a special MEAP application, it is necessary to change the USB driver
setting.
For details, refer to specifications of MEAP application side.

●
Setting the USB driver for each USB device (MEAP driver preference
registration)
If it is set to use the system driver, the conventional applications that support the MEAP
application driver cannot use the USB input device.
Therefore, for the USB drivers used by USB devices/MEAP applications, there is setting
function (MEAP driver preference registration) to give priority to the MEAP driver.
If you register the ID of the USB device by using this function, the USB device can use the
MEAP driver despite the Additional Function settings.
Using this function requires the conditions below:
• Supported MEAP SpecVer: 26
• Describe the idVendeor(VID) and idProdutc(PID) of USB device in the manifest or activate/
deactivate the VID and PID by calling API from MEAP applications.
The driver setting that is used in a manifest file is reflected in the following timing.
When registering from a manifest file.
• The registration will be enabled when an application is activated and device is
restarted.
• The registration will be disabled when an application is stopped and device is
restarted.
