WSL2 and Ubuntu 20.04 - Femto Bolt --- libEGL warning: failed to open /dev/dri/renderD128: Permission denied

[marcomasa]

I am using a WSL2 and Ubuntu 20.04 environment to run the Femto Bolt camera with ROS1.
I've managed to make it work enabling systemd and USB-sharing,
so i can actually start the camera node and view the pointcloud in RVIZ.

However, when i enable subscription to the registered_depth topic, my CPU load rises to 100% and i get the following error message:

..
[ INFO] [1727168158.129323099]: ====Enable frame sync====

I have already updated the Mesa driver:

I also noticed that due to how the UDEV rule is written (space between 'Femto' and 'Bolt'), there are 2 entries in /dev

UDEV rule excerpt (line 12 in 99-obsensor-ros1-libusb.rules) :

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2bc5", ATTRS{idProduct}=="066b", MODE:="0666",  OWNER:="root", GROUP:="video", SYMLINK+="Femto Bolt"

/dev entries:

user@machine:~$ ll /dev/ | grep 'Femto'
lrwxrwxrwx   1 root root          15 Sep 24 09:59 Femto -> bus/usb/002/002
.
user@machine:~$ ll /dev/ | grep 'Bolt'
lrwxrwxrwx   1 root root          15 Sep 24 09:59 Bolt -> bus/usb/002/002

I need help here, since this also affects (although much less) the framerate of the aligned cloud in a recorded bagfile.
Is there any workaround?

Our engineers have tested the Femto Bolt on WSL2 using the C++ OrbbecViewer, and the frame rate is normal. You can cross-test with Orbbec Viewer to see if it works normally.
