It seems the offending device is a (FTDI) USB-to-Serial adapter. As soon as I plug it into the USB hub, the permissions in the /sys hierarchy get messed up. However, it does create a /dev/ttyUSB0 device, and it is perfectly usable! So I plugged all my devices (WiFi dongle, two...
Sometimes you might see this warning message saying “USB device not recognized”. Throughout my tests, I found that you can ignore this warning message and your Pi Zero works as a keyboard without any additional configuration or drivers installation. So, you can continue and it will work just...
I have a separate blog post with details on how to enable TRIM support if your firmware supports it but it's not enabled by default:Enabling TRIM on an external SSD on a Raspberry Pi. Some drive controllers may also need a firmware update to enable TRIM support, so check on your drive ...
We particularly appreciate the color-coded GPIO header, which makes it easy to recognize respective pin headers. Plus, the detailed silk-screen print on the face of the board makes it clear where everything goes. Customers say there is far less support available compared to Raspberry Pi, but...
Debian Installation steps for ZFC fail with the error messagequoted earlier("This kernel does not include the required loadable module support!"). There are instructions forUbuntu 20.04 Root on ZFS for Raspberry PiandUbuntu 22.04 Root on ZFS for Raspberry Pi, but these are far too complicated....
It must be remembered that a Raspberry Pi usually only activates the screen output on the HDMI output if it can recognize a connected monitor when starting up. If a screen is connected after commissioning, it usually remains off. The reason is that Raspberry Pi does not “activate” the HDMI...
Insert your WiFi dongle and reboot the pi. After the pi reboots, you will see a WiFi icon in the task bar near the right side. You will recognize the icon as a blue up arrow and a down arrow next to each other. If the icon does not appear then pulling out the dongle and reinse...
So, we have used it and implemented it in real time video with the help of the Raspberry-Pi 3 B+ model. We have used Python with OpenCV and with the help of Pi-Cam we acquired the live video and recognize the faces in those live videos. The proposed framework can locate multiple ...
http://YOUR PI's IP ADDRESSCopy 7. Once you browse to the address you should see something like below. Do not be worried if this shows an Apache page as sometimes NGINX does not overwrite the Apache default index page. Configuring NGINX for PHP 1. Unlike Apache, NGINX won’t be automa...
automatically recognize USB and ethernet devices like printers, scanners, and in this case the Raspberry Pi. Bonjour is packaged with iTunes and Adobe CS software, so it might already be installed on your computer. If it’s not though, you can download and install the stand-alone software...
