Unable to access inverter

Hi,

I have set up a server on a Beaglebone Green running Debian. Client is on Win10Homex64. The connection works using a couple of USB sticks.

The purpose of the exercise is to monitor a solar inverter in another building, which has proven to be temperamental (or buggy...). It's an Easun iGrid SV II, which is a rebadged Voltronics unit. When I plug the inverter in, in the client a device shows for half a second, then disappears again, repeating every few seconds.

On the server the log shows:

May 21 09:48:54 beaglebone vhusbdarm[4284]: Found Low speed device [0665:5161] "0x0665, 0x5161" at address 11
May 21 09:48:54 beaglebone vhusbdarm[4284]: Error -1 resetting device 0x0665/0x5161 for capture

After reading through the forum I added ClaimPorts=1 to the end of the config. This suppressed two errors, but did nothing to help:

Is there anything else I can try, before writing it off as incompatible?

Thanks,
Peter.

Have a look a dmesg when you plug the device in. Is there any errors in there?

P.S Thanks for the info about a bug in the preview of this forum

This is odd: when I finished

This is odd: when I finished writing the above msg I tabbed to the Save button and pressed Enter. The msg then disappeared completely. I sat there, looking at it with surprise for a minute. Only when I reloaded the page did it re-appear. Is this normal behaviour for this forum?

Michael

Yes thats strange about the browser, i tried to reproduce the issue yesterday but couldnt and i havent heard from other users with this issue. Im just using firefox, what browser are you using?

Anyway regarding that device. Its not being recognized in the beaglebone first so it cannot be passed properly to virtualhere. Do you have any other board like a pi or something like that, you could try? It might be a bug in the beaglebone kernel. A "low speed" usb device is very rare now days so it might be related to some kernel bug in the low speed controller in linux.

Beddhist
Firefox latest. I suspect it

Firefox latest. I suspect it's a plugin, then.

I have no other SBC, but a Linux PC or two in storage that I could try. I think I'll flash the BBG with the latest image first and if that doesn't work I'll try a PC. When connected to a laptop the software talks to it OK, so we know it works.

I had a look at the program and it does not seem to include any USB drivers.

Michael

Yes definately if you can put the latest kernel on the beaglebone that may help. I see its about 4.19 http://www.ti.com/tool/PROCESSOR-SDK-AM335X

It doesn't look good, does it? There is Linux s/w for the inverter, but it requires a GUI...

No there is something wrong with that inverter i think. I think its damaged somehow and the USB part is not working anymore

I don't think so:

This is an AMD PC running Linux Mint 19.3. I'm now going to install the driver and I'm hopeful this time it's going to work. Only, it can't stay there. It's way over 40C in that container and I need it for other things.

Michael

OK so if you run the virtualhere server on that it all works now with the win10 as the client?

Maybe its a power issue. Desktop pcs have much better more stable usb VBUS.

Could you put a powered usb hub between the e.g beaglebone and the inverter?

Beddhist

I don't think I have a powered hub. I could try a beefier PSU for the BBG. But it has enough umph to power a USB stick. I don't see that the inverter would be drawing power from USB. Then again, it has other bugs... Chinese bugs...

You mentioned that a device has to be recognised by the host device. As soon as I had connected to the remote port Windows told me it was setting up a new device. I think the BBG kernel is just lacking some piece of info. But then again, I know almost nothing about USB and kernels. I think I'll ask in the appropriate Beaglebone forum.

Thank you very much for all your time and suggestions.

Kind regards,
Peter.

The sweet smell of success!

So I asked in the BBG support forum and got a somewhat cryptic reply, which I interpreted to mean "try another distro image". So I loaded the latest Ubuntu (instead of Debian). Result:

https://www.dropbox.com/s/edy6j92fajnukwl/Inverter%20monitoring.png?dl=0

It worked at the first attempt.

I want to thank you for writing this excellent piece of software and for the great support you provide here. If I keep this setup I shall buy a licence.

Kind regards,
Peter.

Ok thats great, im still surprised it didnt work with the TI SDK kernel
