I can't detect the 582.1 device by can.interface.detect_available_configs(interfaces="etas")

Additional context

OS and version: win10 Python version: 3.7.9 embed python-can version: 4.2.2

import can
configs = can.interface.detect_available_configs(interfaces="etas")
for c in configs:
    print(c)

print: {'interface': 'etas', 'channel': 'ETAS://VIRTUAL:VXL/CANCARD:100/CAN:1'} {'interface': 'etas', 'channel': 'ETAS://VIRTUAL:VXL/CANCARD:100/CAN:2'} {'interface': 'etas', 'channel': 'ETAS://J2534_HostInterface:1/J2534_System:Kvaser AB|J2534 for Kvaser Hardware|0404/CAN:1'} {'interface': 'etas', 'channel': 'ETAS://J2534_HostInterface:1/J2534_System:Shanghai TOSUN Technology Ltd.|TSJ2534|0404/CAN:1'}

INCA can use ES582.1, but is can not be detected.

Hi, I just tested on Windows 10 with an ES582.1, BOA x64 v2.35.0, python-can 4.2.2 and I get the following output:

{'interface': 'etas', 'channel': 'ETAS://USB/ES582.1:00112233/CAN:1'}
{'interface': 'etas', 'channel': 'ETAS://USB/ES582.1:00112233/CAN:2'}
{'interface': 'etas', 'channel': 'ETAS://VIRTUAL:VXL/CANCARD:100/CAN:1'}
{'interface': 'etas', 'channel': 'ETAS://VIRTUAL:VXL/CANCARD:100/CAN:2'}

It's weird that you do get an output from BOA but it's not listing the ES582.1. I would have the following questions:

• Do you use different BOA implementations with Busmaster / python-can? I.e. 32bit vs 64bit?
• What version of BOA are you using?

We have the same issue: that python-can finds some things when searching for etas interfaces (virtual Kvaser and Vector devices my case), but not the physical ES582.1 dongle.

When playing around we realized that it is a 32/64 bit issue somehow. With 64-bit Python-3.9 it does not work, but with 32-bit Python-3.9 i does work. Unfortunately, using a 32-bit Python version is not an option for us for other reasons.

I have BOA v2.35.0 and tested with python-can 4.2.2.

I have solved this problem by installing the latest driver via etas hsp and then installing boa consistent with the python version

Sorry to be nitpicky here, but did you install both the newest x86 and x64 version? I don't want to rule out an issue in python-can, but judging from the answer from @luojiaaoo, it might be related to your setup.

[andebjor]

did you install both the newest x86 and x64 version?

Yes, I created separate virtualenvs with 32 and 64 bit Python-3.9. I only have the 64-bit BOA installed though (but it includes both 32 and 64 bit libraries it seems). I also tested with 64-bit Python-3.11, with the same result that it can't find the physical device.

I added some printouts to the function that attempts to find the devices, but I couldn't see anything obviously wrong there. But it find nothing on the USB device tree for some reason. Well, in 64-bit. In 32-bit it works as expected.

My hunch would be that it's actually an issue inside the (64-bit) BOA libs, but I really don't know.

Sorry for replying so late. I really don't know what could be the issue here. I worked fine with x64 on my machine. Can you maybe try a fresh installation? Other than that, I'm kind of clueless.
