I recently experienced problems connecting to Samsung Android devices with Android Studio from my work computer.
No Connected Devices were available.
I checked Device Manager and noticed a warning for: SAMSUNG Mobile USB Composite Device
Checked Properties and noticed the Device status:
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
I checked driver details and noticed that the driver was unexpectedly: usbpcap.sys.
(The problem occured after installing Wireshark and USBPcap…)
I decided to uninstall USBPcap. However this didn’t solve the problem, but changed the message for driver details to:
No driver files are required or have been loaded for this device.
Fixed the problem this way:
1. Clicked: Update Driver…
2. Clicked: Browse my computer for driver software
3. Clicked: Let me pick from a list of device drivers on my computer
4. Selected: SAMSUNG Mobile USB Composite Device Version: 2.12.4.0 [24-08-2016]
5. Clicked: Next
6. Noticed the message: Windows has successfully updated your driver software
7. Checked driver details, which now had the desired driver file:
C:\Windows\system32\DRIVERS\ssudbus.sys
This fixed the problem. It was again possible to connect to Samsung Android devices from Android Studio.
