Hello,

I am able to compile this utility for linux however htt_util --scan does not show any devices. as a sanity check i verified the device is visible on windows with the precompiled binary. I can also see the device is loaded using lsusb. Any tips on getting this to work in linux?

Likely a permission issue imposed by the OS, can you try with sudo ?

If that works you'll have to add a udev rule to give users permissions to touch the device :

Code: Select all

ATTR{idVendor}=="1b3d", ATTR{idProduct}=="14c9", TAG+="uaccess"

will likely do it, but i don't have system to test this on at the moment so you may have to get creative here.

Found some time to test on Linux, the following udev rules will allow regular users to use the htt utility

Code: Select all

SUBSYSTEM=="usb", ATTRS{idVendor}=="1b3d", ATTRS{idProduct}=="14c9", MODE="0666"
KERNEL=="hidraw*", ATTRS{busnum}=="1", ATTRS{idVendor}=="1b3d", ATTRS{idProduct}=="14c9", MODE="0666"
