I have a module with ADB enabled running the exact same firmware (and options) as another module:
The other module is connected to a Linux machine and adb works fine. However, on this module on windows 10, I just can’t access the adb shell: adb devices is empty, while I can see the ADB port in the device manager.
I tried running windows 10 without driver signing, with the manual changes to android-winusb.inf, and even after adding 0x1199 then instead 1199 to my userdirectory.android\adb_usb.ini : adb devices Is always empty
I did adb kill-server, nothing helps, even if I have in the device manager “Android Composite ADB Interface”. Also I can send AT commands with putty, so the problem is just with ADB.
I have read Adb devices - Win 7 x64 no devices attached - any ideas? but I still can’t make it work.
I read https://forum.sierrawireless.com/viewtopic.php?f=177&p=32430#p32430 but it did not help either: my DM and NMEA port are showing up and working.
