Hi pegu, Glad to hear you got this working now! Thanks a lot for all help and suggestions. It’s visible using lsusb: In the end this was easier than I thought it would be and it was a whole lot of fun. With this knowledge I could send messages to my inverter and get data back.

This one is as far as I can find not available for ARM devices. Are you new to LinuxQuestions.

Next you need to see if you can create the same traffic from pyusb. Some random tries to communicate with it failed. Semuconductor is quick, simple and absolutely free. So I opened a second wireshark instance so I can compare the two side-by-sidestarted capturing in this one and then started python and setup the usb device there.

What value and what index?

The bottom panel contains the raw hexadecimal and text representations of that data side by side, while the middle one contains the interpretation of that for this protocol. What request byte are you sending? At that point you should have some useful USB data.

Let it go until you feel the application got data through USB that it understands, stop it and stop the capturing in wireshark.


But I need my software to run on an ARM device. You just need to make sure that it exists. Did you get it running with this answer? You are currently viewing LQ as a guest.

Until now I did this: Was I going to get in a car and drive there for capturing the communication between the stock software and inverter on my laptop? I’m using Java on a Raspberry Pi, but if you have just any functional code, no matter in a what language e.

I need really some help on this. This software runs on 32 and 64 bit windows, linux and mac, which is already an impressive list.

That is really most of what I needed. Please check your device availability with ‘lsusb’ and make sure you have an up-to-date version of NUT. I think it is because don’t support Slackware or it is a 32 bits software. BB code is On. This device cannot do semiconductod on its own. Googling those function names, it turned out that most of this driver is actually just the regular open source libusb driver is it even legal for them to publish a closed source driver containing the libusb code?

From that point you need to look in wireshark at the USB data going back and forth. Thank you for following up on this thread and posting the results for the rest of the Zed community.
