No USB devices detected in Android Studio 6.0.1 - android-studio

I used to run applications in my Redmi 3s Prime device. Usually it worked, but now it's showing as no USB devices detected.
Developer options and USB debugging is ON, but it is still not detecting. What should I do?

Please check the Android Studio "event log" information.
If the information is like "ADB server didn't ACK * failed to start daemon *", it means that other software holds the port. Referring to this can solve it.
If you cannot find log information, probably it failed to install the driver.
You may disconnect the phone from your computer, restart the mobile phone and try again.

I have a Redmi 3S and that happened to me too. I solved it by installing the correct drivers from here and MI PC Suite and connected the device.
Also in developer options, turn on "Install via USB", "USB debugging" and turn off "Verify apps over USB". If nothing works, try another USB cable or other port.

Restart PC, Restart phone, if no luck,
Try installing usb driver from this link

and try again

Download suitable USB Driver, ADB driver and fastboot driver for Xiaomi Redmi 3s Prime from below link and install them on your computer.

Mac node serial-port not detecting connected USB device

I am using node serialport library in my Simple node console application.
I Installed the required driver for the USB Dongle and seems like its not getting detected.
But when i checked the mac i can see the device listed
All i can see is
path: '/dev/tty.Bluetooth-Incoming-Port'
I am expecting to see the CEL EM3588 Zigbee USB stick in the list.
Am I missing something?
const SerialPort = require('serialport');
SerialPort.list().then(o=>{console.log(o)});
Finally figured the solution.
Actually even after installing the Driver for the particular dongle, Security in my Mack Was not allowing it to load.
I manually had to allow the driver to run from the Apple-->Security &Privacy -->General Tab.
Image Attached,
Once I clicked the allow button after installing the driver it started showing-up.
I ran the command
`npx #serialport/list`
and I started seeing my connected dongle

Android Device Monitor/DDMS can't connect to device over network

I am trying to debug a memory leak on a Android based VOIP desk phone with Android Studio 2.1 (For what it's worth it's a Grandstream GXV3275 phone, which has a 7in Android tablet embedded in it).
As best I can tell this device has no direct USB connection. I've enabled "Developer Mode" on the phone and am able to connect to it using "adb connect" from the command line. I can use Android Studio to then download and run/debug applications over the network.
But Android Device Monitor will not connect to the device and the phone does not show up in Device Monitor's list of devices. In the Device Monitor's console i see:
[2016-08-30 15:17:32 - DeviceMonitor] Adb connection Error:EOF
[2016-08-30 15:17:32 - DeviceMonitor] Connection attempts: 1
[2016-08-30 15:17:33 - DeviceMonitor] Connection attempts: 2
[2016-08-30 15:17:34 - DeviceMonitor] Connection attempts: 3
Any ideas how to make Device Monitor recognize devices over the network?
Well, the alternative is to use the Android Monitor tab built into Android Studio. This does indeed seem to work without a direct usb tether. Android Monitor supports initiating GC and performing heap dumps (HPROF). The downside that I have seen, is that performing an HPROF dump temporarily disconnects my ethernet connected Android desktop phone from the network.

how to update prolific USB to serial driver?

I have a device (R31D) that read RFID card with USB port(convert serial port to USB port). When I connected it to my computer, ( windows 8.1 - drivers update - X64 ) , It does not work .
When I checked it in device manager it shows small yellow alarm on Prolific USB-to-Serial port(COM3). and when I want to connect to my device with putty. show this error : unable to open connection to COM3. Unable to open serial port.
solved the problem.
First should remove all drivers that related to prolific
second install old version of prolific (I used 2009 v).
then it works.
I have wasted enough time on this subject I will share my final answer regarding "Please install corresponding PL2303 driver to support Windows 11 and further OS"
Device Manager -> Ports COM
Right-click "Please install corresponding PL2303 driver to support Windows 11 and further OS"
Update Driver -> Browse my Computer for drivers
Let me pick from a list...
You probably have old Drivers installed from ages gone by. If not go get PL2303_Prolific_DriverInstaller_v1_12_0.zip
Once you have the legacy drivers, simply chose an older one.
It appears that if you "force" Windose 11 to use a specific Driver it doesn't keep throwing it away.
This solution Survived a Reboot and a Windows Update.

Android 6.0 device not recognized by adb on Linux after reboot

In Samsung Galaxy S6 Edge with Android 6.0, when the device is rebooted, phone complains that the connected computer doesn't recognize the phone and the device is not any more reachable over ADB from the connected Linux PC. The phone in fact instructs user to install proper drivers for Windows or Mac OS, but as the phone is connected to Linux host, there is no help here.
This means, that in order to continue debugging over ADB, one must manually toggle the USB mode from phone from MTP to PTP, after which phone is connected through ADB again. This makes test automation impossible, as the test scheduler needs to reboot the target device between test rounds.
With previous Android versions, rebooting the device remotely and getting ADB connection back was possible, but with Android 6.0, this became a problem. This particular device had earlier Android 5.1 and there were no problems with remote reboots.
As manually toggling of USB mode solves the problem, it might help, if this mode could be automatically toggled after reboot. So far, only solutions I have seen require device rooting and that is out of question.
Does someone have any idea, how Android 6.0 device could be automatically recognized by ADB after reboot?
The solution was after all simple: the Linux user, who starts up the adb server, needed to be added to the "plugdev" group. This group was defined in file /etc/udev/rules.d/51-android.rules with line:
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666", GROUP="plugdev"
With previous Android versions, this didn't seem to be important as we didn't have any users in that group and everything worked fine.

How to connect plantronics wireless headset to windows 8

When I try to connect my plantronics wireless headset via Bluetooth to my windows 8.1, I find that the device is not visible to pair.
Hence I am not able to connect to it.
I have made the settings to enable my laptop detect the bluetooth devices. Still its not able to search.
Try to install [Broadcom Bluetooth 4.0 Driver for Windows 8.1 ] LINK=>> 1 !
At least works fine on my HP-EliteBook-8570p with stereo "BlueDio 99B" headset. After switching the headset ON the Windows connect the device automatically, and switch Audio-Stream into new-attached device. Optimal!
PS - Unfortunately it is still the Problem with Windows 8.1 + Skype( MIC-Problem) :( Windows 8 is the first OS, than not support Skype at all! ;)
