I went at the problem from another direction and it is working well now...
Rather than query each device for its number, I make a system call to read the /proc/pcan file and parse it from there. Specifically, 'cat /proc/pcan | grep 0x001c' since it is the same for all USB devices.
From here I can ...

Re: Fixed /dev identifier to physical USB port
Hi,
Using a Windows machine I gave my two devices unique device IDs.
As far as the devices go, I was working on a workaround before your response. To check which physical adapter is at each channel I:
- Loop through each channel and check its channel status.
- If it is available I initialize it ...

So if the device is ...

Loopback on PCAN-USB for debugging
Hi,
I am looking to put my PCAN-USB device into loopback mode for debugging purposes. In a post written in 2014 ( http://www.peak-system.com/forum/viewtopic.php?f=59&t=1144&p=3082&hilit=loopback#p3082 ) it is stated that this functionality is not available on USB devices. Is this still the case?
