| have attached a USB logitect USB 2 camera to nvidia jetson tx2.
I am unable to see it in /dev.
If I do ls -l /dev/ I see /dev/video0 which is for the on board camera.
i think there is no driver for the camera but I am not sure which driver to install or where is the software.
The camera is visible in lsusb.
Under lsusb there will be an “ID” field with a format like “1a2b:1234”. Use that for your device, then post a verbose listing:
sudo lsusb -d 1a2b:1234 -vvv
Also it would be useful to list “lsusb -t” to see which USB speed/standard it is running under.
This will hopefully help identify the camera. Or, knowing the exact model of the camera would help.

In the “lsusb -t” (“tree” view) the camera is missing. In the non-tree view the camera shows up. It shouldn’t be possible for a device to be visible in one view, but not the other view (it’s two views of the same model). Was the camera plugged in at the time of the tree view? If it was, then this is indeed a very strange problem.
Just to note, in tree view the keyboard and mouse are connected to an external HUB which is in turn connected to the USB2 mode root HUB (the HUB which is internal to the system…this is the connector on the Jetson itself). The USB3 mode root HUB has nothing listed when in tree mode. For your particular case, is the camera plugging into the USB3 port, or to a HUB which is on the USB2 port with mouse/keyboard? If the camera goes to a HUB, is it powered or unpowered?
The detailed “lsusb -vvv…” may be missing information (probably not, but I want to be sure). Could you try using sudo?
sudo lsusb -d 046d:0809 -vvv
I see on the Logitech web page the camera is USB2, so there should be nothing missing regardless of whether the camera connects to a USB2 port or a USB3 port. Also, the web page about this camera indicates it is standard UVC, so no special drivers should be required.
If you run “dmesg --follow” you should see the dmesg output live as it occurs. Start without the camera plugged in, then show what the output is as a result of plugging in the camera.
Hi linuxdev,
I was under sudo -s . So the output i gave you is with sudo.
although I am using a powered hub, after I reconnected the device i got:
[ 2202.677429] usb 1-2.1: USB disconnect, device number 6
[ 2205.946891] usb 1-2.1: new full-speed USB device number 7 using xhci-tegra
[ 2206.048498] usb 1-2.1: not running at top speed; connect to a high speed hub
[ 2206.174170] usb 1-2.1: New USB device found, idVendor=046d, idProduct=0809
[ 2206.181175] usb 1-2.1: New USB device strings: Mfr=0, Product=0, SerialNumber=2
[ 2206.188611] usb 1-2.1: SerialNumber: B42F0765
[ 2206.193637] usb 1-2.1: rejected 1 configuration due to insufficient available bus power
[ 2206.201726] usb 1-2.1: no configuration chosen from 1 choice
I also used:
echo -1 > /sys/module/usbcore/parameters/autosuspend
You may disable usbcore autosuspend at boot time rather than at run time.
Add
usbcore.autosuspend=-1
to /boot/extlinux/extlinux.conf and reboot.
This shows the reason (a device with no power won’t show up…power was cut off):
[ 2206.193637] usb 1-2.1: rejected 1 configuration due to insufficient available bus power
Something to think about is that as devices on an unpowered HUB are added that the last device to be added could consume more than the sum total of what one port allows. So the device being plugged in might not be the largest consumer of power, but it is the device which crossed the power availability limit boundary.
In your case you say it is a powered HUB, but the dmesg indicates otherwise. Every powered HUB I know of reverts to a working unpowered mode if the power adapter is removed. It sounds like your HUB has lost power due to defect or other reason (I’ve had this happen when the power connector was not properly seated). If not, then the HUB itself has reported to the root HUB that power consumption was exceeded at the moment this device was plugged in (which in turn implies power consumed exceeded even the limits of a powered HUB spec…which goes to individual ports, not sum total ports…and is far higher than limits for unpowered ports).
Maybe the hub is not good enough? Have you tried with another, high-speed, externally powered hub?
Also, as linuxdev says, check to make sure power is actually plugged in and available in the hub.
