Device Enumeration Order

[daniel.trevitz]

Will the 6 CAN ports always enumerate in the same order?
For example, port 1 will always be PCAN_USBBUS1, etc., etc.
I am assuming no other PCAN USB products are installed on the PC.

Hello,

yes, it will always enumerate in the same order. If no other PCAN-USB based device is attached to the computer, the channels 1 to 6 of the PCAN-USB X6 are PCAN_USBBUS1 to PCAN_USBUS6 respectively.

Awesome! Thank you!

Hello,

we have 2 pcan-usb x6. After reboot the ports sometimes does not enumerate in the same order.

Is there any way to configure the interfaces according to the usb-ports or something else?

thx

hey marvin,

we use ubuntu 18.04 with build-in drivers

[M.Heidemann]

Hello,

the mainline kernel driver does not allow for fixed enumeration.

Please use the proprietary PCAN-Linux driver package and build for NetDev-mode (Compatible with SocketCAN):

Please see the PCAN-Linux documentation, chapter 3 -"Installation" for information on how to build the driver
in NetDev mode:

You can set the channel number according to the device number, a detailed description for setting the device-number and
use the "assign" parameter to have the channel-number adhere to this device number is detailed in the following forum post:

For further information on the assign paramter, please see the PCAN-Linux documentation on page 39:
