I am new to using the STM32 nucleo board. I have bought an STM32F767ZI nucleo board. I installed the STM-link utility V4.6 version and stm-link009 drivers. When I connect the micro-USB port of nucleo to my computer, its not getting detected. The COM LED LD4 is blinking. From the manual, I saw that its trying to connect if the LD4 RED led is blinking.
I have tried different computer and different USB cables.
The problem was with the micro-USB cable. I had tried different USB cables which I thought was good and worked with my phone to transfer data. But didn't work with STM32F767ZI. I bought a new one and it worked well.

I've got a new STM32L496G board I'm trying to program but running into an "st-link no target connected" issue. I've tried reinstalling the drivers multiple times but this hasn't resolved the issue. I'm running dual booted off a Mac and have to use a USB converter to connect the device, so I was wondering if using that converter could be causing the device to not be recognized. I'd appreciate any insight, I'm completely new to working with the board
I tried working with my RPi Pico today and my computer doesn't recognize the usb I triple checked the cable is power and data. And yes I'm holding the button
I've also had this annoying issue. Seems to happen even more often on the Pi Pico W.
Use my laptop USB-C port to connect via a USB-C to USB 3.0 hub and this happens every so often.
Bought a powered hub from Amazon: "UGREEN USB C Hub 4 Ports, USB C to USB Hub 3.0". It has a separate USB-C power input in addition to the laptop USB-C connection and it works fine when no other USB devices are connected to the hub. Seems to be an issue similar to what Foibled2 mentioned where the underlying issue may be power related.
I'm struggling with the same thing. Other than uninstalling in Device Manager and rebooting (sometimes several times) I can get it to recover.
There must be a better way.
I've seen references to Zadig, etc. But finally figured out the issue in my circumstance.
I disabled all of my other USB serial devices (Prolific USB for GPS tracker; and CH340 USB for Android Nano).
After that, I could plug / unplug my R Pi Pico between application and USB drive mode without rebooting.
Works now as advertised. Hope this helps short cut a few hours for someone else!
I'm working on a project where i have two raspberry PI connected in ad-hoc mode. the project is for transmitting streaming data using UDP supported by a self developed ARQ protocol for reliable data transmission. the thing is that i want my 2 raspberry Pi to be synchronized! i tried to install the NTP server on one device and get the time on the other (as an NTP client) but when i wanted to reconnect them on ad hoc mode again, it was necessary to reboot the devices where the time was lost because the devices don't contain the hardware clock!
is there are any idea how to synchronize the two raspberry in ad-hoc mode ?
thank you!
I wrote an app which runs on two android tablets at the same time. The app enables both devices to communicate with a java server which is running on the pc, via WLAN socket communication.
The problem with the WLAN connection is that it doesn't always seem to be reliable. So I wanted to setup a socket communication to the server via USB cables.
My problem no is how to connect TWO android devices to the server via USB cables. I found this tutorial for connecting ONE device to the server via ADB, but I see no possibility using this approach for two devices:

Has anyone an idea how to solve it? Thanks!
If your tablet is runs ICS or newer Android OS, then it is very likely that it has OTG capable micro-USB socket, and you can add a USB-Ethernet dongle, and then connect the 2 tablets to your PC over ethernet, instead of USB. This, might be the most elegant solution.
Of course, you'd need a switch (or hub) to connect them together. Also note that, not all USB-Ethernet dongles may work out-of-the-box. You might have to experiment with few models, especially the el-cheapo ones to get them to work.
I made an WinCE 6.0 R2 image and load it into VMWare Player 3.1.3. The host operating system is a Windows XP Sp3. I followed this article and all worked fine (the article uses VMWare Workstation, but it worked fine also with VMWare Player).
My final goal is from the virtual machine WinCE to use the Bluetooth USB dongle attached to the Windows XP host computer. In the WinCE image I had added support for Bluetooth USB like in this Mike Hall's post. Also I want to mention that I had included support for USB Host when I created the BSP, and also USB drivers are checked.
When I go in WinCE -> Control Panel -> Bluetooth Device Properties, Bluetooth Manager is launched. But if I try to make a "Scan device" I am getting the following error:
Bluetooth hardware error 10050 (controller not present)
But the dongle is attached to the VMWare Player and disconnected from the host, so theoretically the transport layer is controlled by the virtual machine and WinCE can talk with EHCI of the USB.
Can anyone give me a hint to follow? Any suggestions are welcome.
I have no idea whether the stuff described at http://www.codeproject.com/KB/windows/bth4devemul.aspx is required in your case...
There the FreeBT.NET stack is installed on the host PC to enable the WM emulator to use a host-attached Bluetooth dongle...
