Interestingly I have similar issues when I plug in a Pegasus Astro PPB which has an FTDI device inside. It has worked OK until last weeks update. Now it will work plugged in to the hub, so long as it’s not into port 1 (or could that be port 7? it’s the leftmost port ...
... bam! The permissions get messed up, and lsusb (and libusb) no longer work properly Well done for figuring it out. That looks to be a bog-standard FTDI device so it does seem a bit odd. I'll dig mine out and see if I can replicate or shine any light on things. Update : Using FT232BM rather than ...

The ID-12LA simply has a TTL UART interface, the USB adapter board is simply a USB-to-Serial adapter (FTDI FT232RL), you should be able to just connect it to the RPi's UART (do make sure the logic levels are the same, don't connect a 5V device to the Pi directly).
Hi melvus, I am faving the same problem as yours. I've tried using pyserial but it still doesn't work.
Do you already know the solution?
Thanks before!
Hello, I follow the turorial of David Welch (https://github.com/dwelch67/raspberrypi-zero) - I wired an FTDI dongle (3v) to my rpi - I added a reset switch - I copied the bootloader.img as a kernel.img - I reset the RPI, pasted the blinker01/notmain.srec into putty (does not ...
... - nonzero urb status: -71 Then the USB device disconnects (and sometimes reconnects). In my case it happens with a FTDI FT4232. Any help would be very appreciated!
... I'm trying to understand how connection type changes sensor accuracy. Is there any link or a supplier that is in the USA? thank you A $10 FTDI makes any serial device USB. Check Amazon, Adafruit, Pololu for US shopping.
The pi 4 has a bunch of UARTs but you can also use an FTDI module - which is a ttl serial to USB interface thingie. Very handy and they allow you to play with serial devices using your non-pi computers as well.
... Unless I need RTK (2mm accuracy) I am fond of the GPSV5. It's very simple to just plug into either the gpio serial or USB (although it needs an FTDI for USB) and start receiving data - no need to set up anything if you don't want to. (although an external antenna is helpful).
Just wanted to note, I have the exact same problem here with one of my 3B+ # modprobe ftdi_sio modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.19.97-v7+/modules.dep.bin' modprobe: FATAL: Module ftdi_sio not found in directory /lib/modules/4.1...
... However, that is apparently wrong with the latest firmware. Connecting RTCK resolved all the problems. It's the blue wire on the common USB FTDI FT232H, goes to pin 16 on the board. Also doesn't hurt to connect ground (black), which is usually omitted in what I found in online guides.
Hi I installed python 3.8 however it doesn't seem to work properly so I have been trying to remove it but I'm struggling. I receive the following error when I run the command : sudo apt-get remove --purge python3.8 ----> E: Unable to locate package python3.8 E: Couldn't find any package by glob 'pyt...
It is, but the link only shows FTDI devices which have unique serial numbers. For Prolific or QinHeng adapters that don't expose a serial number, you pretty much have to go by physical port numbers in /dev/serial/by-path/. You don't have ...
... sure if this is a fundamental or dumb question. I'm about to integrate a Rpi 4 into a big project in which the Rpi constantly acquire data from a FTDI chip and occasionally read and write to some files. I'm just aware that there are some limits on read and write cycles of a SD card and the SD ...
... problem only happened while writing (console->RPI, ie. RX/GPIO). So I double checked all GND connection to the external board (the one with the FTDI) and noticed the ground cable to the FTDI was not perfectly plugged in, this probably caused the GND reference to be missing from time to time, ...
... displays it on the screen. The uart settings are 9600 8N1. Anyone have similar issues with the FT232R or have any ideas? I need to use the genuine FTDI adapter as it has the certifications required. The program is very simple, only receives.

... No. You don't need to do anything to the FT232R. You may want to program a suitable sensor name + serial number using the FTProg tool from the FTDI site for easier identification from your software. Be warned that the FTProg tool may kill adapters that use counterfeit FTDI chips.
