Issue with USB Camera Disconnecting on VOXL2

Daehan Won

Hello,

I would like to use a USB camera connected to the VOXL2. My test environment is as follows:

Hardware setup:

VOXL2
VOXL 2 Ethernet and USB Hub Add-on (MDK-M0062-3-00)
USB Camera

The camera is connected via the J11 USB port on the MDK-M0062-3-00.

VOXL2 <--> VOXL 2 Ethernet and USB Hub Add-on(J11) <--> USB Camera

J11 Pin Description:

VBUS_PORT3 — 5V VBUS, 1A limit
USB1_HS_CON_D_N — Host Port USB_D-
USB1_HS_CON_D_P — Host Port USB_D+
DGND — System GND

However, when I first power on the system, the video device is recognized correctly. After about one minute, the video device disappears.

Is there any additional configuration or setup I need to perform?

Vinny

Hi @Daehan-Won
To help us, what camera and how is it connected (cable details, with photo will help)
We want to first understand how much power it needs.

However, if it appears upon boot up, that is usually the worst power draw (in-rush), so I'm not inclined to think this is the case. It may be loose wiring, which is why a photo of your cable setup will also help. Even the slighest intermittent glitch on USB will create USB reconect events.
You can monitor that in a VOXL console (over ADB) with this command :

dmesg -w | grep -Ei 'usb|xhci'

Thanks!
