There are several abnormal EPIPE errors when the usb device is probed. Could you please rebuild the driver in DEBUG mode:

Code: Select all

$ cd peak-linux-driver-8.4.0/driver
$ make DBG=DEBUG NET=NETDEV_SUPPORT

Open another shell window, then type:

Code: Select all

$ sudo rmmod pcan
$ dmesg -w > /tmp/pcan.log

Back to first shell window, reload now the new DBG driver:

Code: Select all

$ sudo insmod pcan.ko

You can now stop logging by typing ^C in the 2nd shell window. Finally, please send us the resulting /tmp/pcan.log file.

Regards,

Stéphane

Hi,

Thank you for your logs.

Could you take a picture of the serial number of the PCAN-USB please, and send it to us?

Are you using any USB extension cable?

Regards,

Stéphane

IPEH-002022-207244, I used a usb type A to type C adapter, works fine with pcan view app.

Hello,

works fine with pcan view app.

Are you running Linux into a Virtual Machine?

Regards,

Stéphane

[JohnnyT]

Yes, I am using the latest parallel desktop on a MacBook Pro.

PCAN works in my win10 VM / win10 BOOTCAMP, but doesn't in ubuntu VM.

I have a cantact which could also read/write CAN package, it works fine with socketCAN in ubuntu VM.
