Raspberry Pi, lost /dev/ttyUSB0 when plugged in second FTDI cable

I had a RPi setup with 1 FTDI cable. I was able to use /dev/ttyUSB0 in code without issues

When I plugged in a second FTDI cable, with the same vendor and product ID, /dev/ttyUSB1 never showed up, instead I lost /dev/ttyUSB0

lsusb shows that both devices are enumerated correctly.

Now, even when I plug in just one FTDI cable, /dev/ttyUSB0 still does not show up!

How can I get back the ttyUSB0 and ttyUSB1?

Here is the output from dir /dev lsusb and dmesg

Thanks,

Try using the fdisk command. Do a fdisk -l and it should list all the connected devices and you can get the name from there. Then you should be able to mount it. I'm not sure lsusb will give the correct names.

Try using the fdisk command. Do a fdisk -l and it should list all the connected devices and you can get the name from there. Then you should be able to mount it. I'm not sure lsusb will give the correct names.

Your udev rule should control device node creation, try this one.
