Cerbo GX kills USB devices?

Hi all,


I'm currently running a Cerbo GX v2.85 in my camper van with the following USB devices attached:

- a DIY VE direct cable based on a PL2303 chip

- a DIGITUS slim spider USB hub (no clue about the chipset currently)


To the hub there are several other devices connected like a GPS dongle, a Tank 140 and a Daly BMS serial adapter.


After a few hard power cutoffs the to directly to the Cerbo attached devices (VE direct to USB adapter and the hub) are dead. They are no longer recognized anymore by lsusb.

The devices, which were attached to the hub are still fine.


Is there any chance, that the Cerbo killed them?


Cheers,

luphi

@luphi

It's more likely that your DIY VE direct cable is dead. And also worth to notice that using such DIY adapters can cause several other problems, not to speak of voiding warranty.

Hello Stefanie,


thank you for your reply and don't misunderstand me. I don't want to blame anybody for the issue, I just want to understand what might happened.


The DIY cable is just Gnd,Tx and Rx. How can that have any influence on the USB hub, which was connected to the Cerbo's other USB port?


Cheers,

luphi

USB ports aren't isolated. Bad news can travel..
