Hello,  
been trying to install node/node-red-contrib-usbhid by following all the steps with no success.

Through the Palette-Management i get the errors below (truncated)

```auto

```

Through the shell by running the command npm install node-hid --build-from-source --unsafe-perm  
I get the results below:

```auto

```

but still, no nodes are added, and the package shows as uninstalled in the palette management.

my target is to use a usb scanner that reads using a python script successfully and is an HID device.

Thank you.

That's because you installed it in the pi home directory rather than in the .node-red directory.

Hello Colin,

This time i tried to install it with the error below.

```auto
pi@raspberrypi:~/.node-red $ sudo npm install node-red-contrib-usbhid --build-from-source --unsafe-perm
npm WARN checkPermissions Missing write access to /home/pi/.node-red/node_modules/node-hid
npm ERR! code ELOOP

npm ERR! errno -40
npm ERR! ELOOP: too many symbolic links encountered, access '/home/pi/.node-red/node_modules/node-hid'

```

as with the ls -alt i get the below

```auto
pi@raspberrypi:~/.node-red/node_modules $ ls -alt
total 312
drwxr-xr-x 78 pi pi 4096 Dec 21 08:05 .
lrwxrwxrwx 1 pi pi 8 Dec 21 08:05 node-hid -> node-hid

```

so, is the node-hid the same as node-red-contrib-usbhid?  
if not, how can i solve the linking issue above please?

Thank u.

You should not use sudo for installing local nodes. Now you may have files owned by root in your home directory which is likely to cause problems later. Probably best to delete that node and try again. Try

```auto
cd ~/.node-red/node_modules
sudo rm -rf node-hid
cd ~/.node-red

```

and try the install again. Take care with the sudo rm command as you can use that to delete your operating system if you get it wrong.  
I don't know why you are using build-from-source or unsafe-perm, but I assume you have a reason for that.

If you look at GitHub, it would seem the author has lost interest and several people have had install issues ([https://github.com/somebuddy87/node-red-contrib-usbhid/issues/1](https://github.com/somebuddy87/node-red-contrib-usbhid/issues/1)) but some have had some success ([https://github.com/somebuddy87/node-red-contrib-usbhid/issues/3](https://github.com/somebuddy87/node-red-contrib-usbhid/issues/3)) with a 'bit' of extra work.

@zenofmud  
Yes i can see that, the point is i cannot find any other way to read input from an HID Zebra (Symbol) QR Code scanner to nodered.  
do you think there is another way to do this?

If you read the second thread I pointed to, it looks like some people have abeen successful installing the node - with some extra work.

I know of no way to use that scanner, but I don't have one, never used one so there has been no need for me to look for a solution. Maybe someone else has and will give you an answer, but till then, if I needed to use it, I'd look at those threads...

Some HID devices do just look like keyboards etc - so may just send strings into an input field in the dashboard, or use the keyboard node on Pi... but then again - many do not...

Hello,  
Just found a configuration utitlity for the scanner.  
i may change the behavior of the scanner to one of the below, do u recommend any that works with Node-red!

In terminal run  
`tail -f /var/log/syslog`  
Then hit return a couple of times so you get a gap in the output.  
Now plug the device in and copy/paste the resulting syslog output here. Copy/paste if possible please rather than a screenshot.

That suggests it might just appear to be a keyboard. If you open a terminal and scan something does anything appear?

Hi, Did you ever get this working? I am having the same problem on a Pi4 running Dietpi
