sometimes it freezes. Need to run PB IDE with sudo in the terminal. If you run it too many times, it may freeze for a few minutes.
Maybe this is the reason viewtopic.php?p=646123#p646123

Probably the reason freezes in libusb backend.
For testing, I compiled hidapi using hidraw backend and the application never freezes.
To check this, copy this file to folder "purelibraries/linux/libraries/" for PB Linux x86.
You also need to add a line in code for use udev.

Code: Select all

Import "-ludev" : EndImport

When I run in the terminal an application using libusb backend, I see this text.

Code: Select all
