Alright, I'll see if I can dig up the info I need there!

Thank you, by the way, for making an excellent product. The fact that this device always enumerates to the same interface names on every boot means that we can use it reliably.

If possible, I do need help with configuring the PCAN-USB Pro FD in SJA1000 mode in Linux, using the built-in driver.

It would appear that our connected devices are fickle and while they sometimes work in regular CAN mode, more often than not something goes wrong during initialization and one or ...

Well, I can't find anything. It would seem that our old miniPCIe CAN card is defaulting to SJA1000 on both channels. However I can't figure out how to make the PCAN-USB Pro do the same thing! Clearly it's an option, since it is selectable when I connect it to a windows computer and use the PEAK ...

Thanks, that did help! I managed to get things working with an 80MHz clock by specifically setting the TQ and other values, with this command:

ip link set can1 type can tq 125 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1

I will see if the linux driver allows me to switch to SJA1000 mode. I didn't ...

Here's the result of running 'ip -details -statistics link show can1' Notice there are a few differences, the largest being that the USB interface is using an 80MHz clock wthile the PCI is just 8MHz. Will that actually make a difference?

miniPCIe:

can1: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc ...

Hello! An older computer system we use is set to be upgraded. It has a dual-channel PEAK miniPCIe to CAN adapter built in. Unfortunately the new computer won't have a miniPCIe slot or an available PCI slot, so I'm forced to use the PCAN-USB Pro device instead. This has come with some challenges ...

Understood. I'll try installing that driver package to see if it'll give me the functions I need. Thanks!

Thanks for your reply. Does that utility do anything different that the Windows-based utility I already used for changing the PEAK USB's CAN address?

"pcan-settings" does not seem to be installed or available on my system. In fact, I don't think the 'pcan' module even exists on my system right now ...

Hello, all! I've searched for days for a solution to this, before giving up and making an account here to ask for a solution.

I'm running Ubuntu 20.04, and have two PEAK USB CAN interfaces connected. They have different CAN IDs, set using the PCAN utility. By default they will enumerate as "can0 ...
