Describe the bug
No connection to a kvaser device with a simplest demo script (linux, latest kvaser driver CANlib 8.50,
4.5.0 - works perfectly.
To Reproduce
OS: Xubuntu 22.04.5 LTS x86_64 Kernel: 5.15.0-100-generic
driver Kvaser Linux Drivers and SDK 5.51.461
CANlib 8.50 (file libcanlib.so.1.10.12)
- Simplest script and python-can 4.5.0
import can.interfaces.kvaser
try:
bus = can.interface.Bus( interface='kvaser', channel=0, bitrate=500000)
bus.shutdown()
except Exception :
print("Error")
works for me perfectly.
- update to a new version (4.6.1).

Expected behavior
I expected in to connect to the bus as 4.5.0 did.
