Hello,
bumping a really old topic, but a new problem.
case:
- installed proview 5.7 on latest raspbian running on a rpi 3b+
- followed everything, created an opt file, compiler uses it without issues
- but when running and viewing the log file it quotes:
I plc 1657 20-06-18 22:13:44.72 Init of USBIO agent 'VolTest:Nodes-Test-USB'
E plc 1657 20-06-18 22:13:44.72 K8055 Claim interface failed, sts -6, 'VolTest:Nodes-Test-USB'
E plc 1657 20-06-18 22:13:44.72 Failed to inititalize io, %IO-E-INITFAIL, Initialization failed
Is something else tries to use the interface, I'm starting to get a bit worried because until now everything seems to fail what I try to do (cfr cross compileing the pi in a previous topic)
