PCAN-USB FD (IPEH-004022) cannot be initialized

[mac-can]

Peak-System GmbH has released a new product variant of its PCAN-USB FD interfaces (item no. IPEH-004002). These interfaces cannot be operated with the PCBUSB library for macOS. The initialization of such an interface - in CAN 2.0 mode as well as in CAN FD mode - fails with error code 0x4000000 (PCAN_ERROR_INITIALIZE).

Device: PCAN-USB FD IPEH-004002 (Firmware: v3.4.3 latest) Host: M1 Ventura 13.5.2 library version: v0.12.1 (latest)

Hello, I cannot initialize the device correctly using the latest version of the library, I tried python example, Monitor and python-can, same error: Error 4000000: A PCAN Channel has not been initialized yet or the initialization process has failed

Question: Did you get the same error when calling the CAN Tester utility program can_test with a device channel argument?

makemake@uv-pc014mac can_test % ./can_test PCAN-USB1 -v

Then the rootcause could be that Apple removed /usr/local/lib from the library search path; see issue 737920 in the Developer Forum.

If not, then I guess something went wrong when taking over the hot fix (see above) into the main branch. But I cannot test this, because I didn`t have a "new" PCAN-USB FD device.

Yes, it works fine with the hotfix version above, but not the mainline version.

Thanks for confirming the issue. A "new" PCAN-USB FD device for debugging and fixing will arrive to me soon.

Fixed with version 0.12.2
