OTG error and Hid errors

[BiskottoScriptato]

• [✓] I have read the FAQ.
• [✓] I have searched in existing issues.

Environment

• OS: Windows 11 x64
• scrcpy version: 1.23
• installation method: Downloaded the folder from github
• device model: S7
• Android version: 8

When i try to use the otg i get this error:

scrcpy 1.23 https://github.com/Genymobile/scrcpy
INFO: Killing adb daemon (if any)...
ERROR: Could not find any USB device

and when i try to use the command --hid-keyboard i get this:

ERROR: On Windows, it is not possible to open a USB device already open by another process (like adb).
ERROR: Therefore, -K/--hid-keyboard and -M/--hid-mouse may only work in OTG mode (--otg).

Is USB debugging enabled on your device or not? On Windows, there is a problem if USB debugging is not enabled: #3050.

I'm also having this problem. USB debugging is already enabled in my Phone. I'm using Samsung Galaxy S20 FE on Windows 7 Pro.

I'm also having the same problem and my debug is active.

I find a little solution on windows 11.

1- run scrcpy in OTG : scrcpy --otg -s xxxxxxxx
2- back to your shell & force close the process with CTRL + C
3- run scrcpy, now you should got scrcpy without the keyboard

I can confirm the same behavior. USB debugging is enabled, with the normal non-otg version working as intended. It doesn't seem to find my device either.

INFO: Killing adb daemon (if any)...
ERROR: Multiple (5) USB devices:
.
. (Devices left out for privacy, but my Android device is not among them.)
.
ERROR: Select a device via -s (--serial)

Is there any progress on this issue? Thanks!

how do i even mirror screen and use keyboard/mouse controls for me only one of them works in windows10

(You mean keyboard/mouse HID controls, I guess.) Yes, on Windows you can't have both mirroring and HID.

See https://github.com/Genymobile/scrcpy/blob/master/doc/hid-otg.md

Note: On Windows, it may only work in OTG mode, not while mirroring (it is not possible to open a USB device if it is already open by another process like the adb daemon).

is it possible to use the linux wsl instead so i can mirror and have the keyboard/mouse hid controls at the same time

I don't know, I never tried wsl.

But a LiveCD/LiveUSB of a linux distribution should be sufficient to test. You could download the latest Ubuntu, "burn" it to USB key (with rufus for example), and boot on your USB.

I have an interesting case of solving this problem. I have Samsung Galaxy M02. In my windows pc I did not have the Samsung USB Driver and the scrcpy --otg did not work, so I installed the driver and even after that it did not work. Then, I deleted the driver and tried again. This time it magically works as it should. I don't know why did this happen but you can try this method if you are having problems.
