Problem on Mac book pro (M1 Pro chip)

[grougnach]

Hello,

I have sent you an email directly and you kindly reply, but because I still have the problem, I found it could be a good idea to fill in an issue ?

I am trying to make my Kvaser Leaf work on my Mac M1 on Ventura, but I get this output

CAN API V3 for Kvaser CAN Interfaces, Version 0.3.1 (0xaaa925f)
myDriver.GetProperty(CANPROP_GET_SPEC): value = 3.0

+++ MacCAN-Core: device could not be opened (00)
+++ error: myDriver.InitializeChannel(0) returned -95
Cheers!
Program ended with exit code: 161

I have made tests with :

• Memorator pro 5 5xHS : EAN 73-30130-00778-9
• USBcan leaf 4xHS : EAN 73-30130-00831-1
• USBcan Light 2xHS : EAN 73-30130-00714-7
  And on :
• MacBook Pro
• Apple M1 Pro
• Ventura 13..1

Any idea ?

Thanks for your help and the work done !

Hello,

My bad, I read the code and discovered that at least memorator is not supported !! and Leaf 4HS neither.
I am trying to add them but can only get one channel that is detected.
Can you provide clues to make it work ?
Jacques

With 1 channel seems to be OK :

I have no access to the listed devices and can neither test them nor reproduce the issue:

• Memorator pro 5 5xHS : EAN 73-30130-00778-9
• USBcan leaf 4xHS : EAN 73-30130-00831-1
• USBcan Light 2xHS : EAN 73-30130-00714-7

Multi-channel devices are not supported by the macCAN driver.
