USB connected UPS keeps connecting/disconnecting

OuticNZ · 05-09-2020, 02:10 AM

Hey all, wondering if anyone has any ideas on how to fix this? I have Dynamix UPS connected via USB. But it won't stay connected, i.e. its there as a device then disappears. DMESG is spammed with disconnect, and new USB device messages.

If I connect it to a Windows OS it works fine. So its not a hardware issue, or cable issue.

If anyone can point me in the right direction to get this solved it would be appreciated.

Code:

So, what's a dynamic UPS?

@ondoho. This.

Yep, that's it. My specific model is Defender 1600VA

The Windows software works fine but it won't stay connected in a Linux OS. I don't really want to run Windows. I don't know if it's a driver issue, or device identification issue. I have not heard back from the manufacturer.

So it's a power supply, and you can connect it via USB for "communication with sophisticated NetGuard® software".
Seems to me that that's something that's not possible on Linux; or not possible OOTB.
Anyhow, took me 2 minutes to find this: https://askubuntu.com/questions/5637...usb-connection
Might help, might not.
Then tehre's always WINE to try.

Hi,

Something strange for me in log :

Code:

May 7 21:25:56 uncomplex kernel: hid-generic 0003:0665:5161.003E: hiddev96,hidraw0: 
USB HID v1.00 Device [INNO TECH USB to Serial] on usb-0000:42:00.3-3/input0

Is apcupsd able to handle your UPS ?

hth,

Thoughts.
Is it possible that some other device on that lan is also using a ups?

Hi,

@jefro
I partially agree with you

In fact, i think that there is a usb to serial converter somewhere and this converter is giving problems.
