USB Device - usblauncher unable to update from *.lua files
I am trying to make my target board, SabreLite, to be a USB Device; so when I connect the SabreLite to a PC, I want to
at least see the VID and PID in the PC Device Manager. I understand the PC side will need an *.INF file, but the VID
and PID that are hexadecimal should still be updated.
So far i have tried updating the IFS boot script to include the PPS, to launch the usblauncher, and created the
necessary directories for the *.lua files. However, when executing the boot script, the PPS is missing a /var/pps. The
usblauncher is able to run, but when performing usb -vvv I do not see the VID and PID updated to my *.lua files.
When trying to create the missing directory with mkdir, i get an error: Function not implemented.
I also tried a QNX recommendation to run usblauncher through the SD mount. I am able to get the usblauncher to perform,
but when using usb -vvv I am still seeing the USB controller being a Hub, when I want it to be a device with the
information from the *.lua files. Also I am still unable to create a directory, when using mkdir.
So I would like to know if i need to mount a different binary for creating directories (mkdir)? Also is the PPS really
necessary to execute the usblauncher, so it can update the usb controller with the necessary *.lua files?
Thanks in advance.
