USB_OTG_FS for stm device not working on linux - linux

I am using a adafruit STM32F405 feather, and have written a program for it in the stm32cubeide. I have enabled USB_OTG_FS and also selected VCP under USB_DEVICE under middleware. I sent a simple message using CDC_Transmit_FS() within my main.c file. I wanted to then display the message using minicom but the stm32f405 is not recognized as a virtual com port when i plug it in. Please can anyone help with this problem?
This what i get from dmesg

It appears that there is an error when reading the usb device descripter, any ideas how i can solve this?


HAL_PWREx_EnableUSBVoltageDetector() at end of MX_USB_DEVICE_Init for older Firmware it appears.
I updated from Jan to July release of IDE, MX and STM32CubeF4 releases and my USB_OTG_FS started working (the call above is not present in the latest).

Linux does not create /dev/ file for USB modem

My USB modem called Anydata W150. My goal is to send AT commands to the modem via USB and get some information from it.
When I'm connecting the USB modem, first of all it connects for a few seconds as /dev/ttyACM0,
then changes it's mode to flash drive mode and then becomes an internet interface with address like enp0s...
Here is my lsusb output.

The device with address 0e8d:2004 is my USB modem.

I googled a lot and found out, that I need to create udev rules. I created rules file with path /etc/udev/rules.d/99-usb-modem.rules
Contents of the file:
ACTION=="add", KERNEL=="enp0s*", SUBSYSTEM=="net", ATTRS{idVendor}=="0e8d", ATTRS{idProduct}=="2004", SYMLINK+="/dev/ttyUSB10"
So, I'm trying to create a symlink, but it does nothing. I tried a lot of variations of this file and it's contents but nothing is working.
Also, I tried to load drivers via modprobe command. Command syntax was like this:
# modprobe rndis_host
And also tried this with defining the ID from lsusb.

Read from HID device

I have remote HID device but seems to be constantly reconnected.
Is there a way to use it on linux? For windows computer the driver is available but not for linux. I assume it's possible to be used but doesn't have clue how.
I try to list devices with python code like:
import evdev
devices = [evdev.InputDevice(fn) for fn in evdev.list_devices()]
print (devices)
for device in devices:
print(device.fn, device.name, device.phys)
but script doesn't list any device. Appear that device is constantly reconnected. Here is lsusb and dmesg output:

STM32 Virtual COM Port device not work then linux start

I have a device(STM32 Virtual COM Port).In Linux it is detected normally /dev/ttyACM0. After starting the operating system, I do not receive data from the device. If turn it off and back on it works fine. The problem appears only when I reboot the operating system. Can you tell me how to make it work after restarting the OS.
Its my dmesg

OpenOCD cannot open connection to STM32L4 board (STEVAL STWINCSV1)

I have a STEVAL STWINCSV1 board with an STM32L4R9 chip connected to my computer via USB. I am trying to use OpenOCD to flash a new image. I am using the command openocd -d -f board/stm32l4discovery.cfg to try to open a connection to the board. Here are the contents of the cfg file
# Explicitly for the STM32L476 discovery board:
# http://www.st.com/web/en/catalog/tools/PF261635
# but perfectly functional for any other STM32L4 board connected via
# an stlink-v2-1 interface.
# This is for STM32L4 boards that are connected via stlink-v2-1.

When I plug in the board via USB and check the output of dmesg | grep usb, here is what I get (I plugged the board in multiple times):

When I run openocd -d -f board/stm32l4discovery.cfg, here is the output (pastebinned since it was a bit long): https://pastebin.com/biVLuf7U
Does anyone know what might be going wrong here?

I figured out the issue. First of all, the eval board I was using does not support stlink over its usb port, so I had to use a stlink/v3 mini external programmer instead. Also, the latest OpenOCD release on my distro did not support stlink/v3, so I had to compile OpenOCD from source. That fixed my issue.

How to prevent this?

This command seems helps me:
