I'm trying to connect to a KaiOS device with adb but whenever I run adb devices I get an empty list of devices, however when I run lsusb I get:

Bus 001 Device 017: ID 1782:4001 Spreadtrum Communications Inc. Spreadtrum Phone

I've done all the pre-setup which include:

  • Adding SUBSYSTEM=="usb", ATTR{idVendor}=="1782", MODE="0666", GROUP="plugdev" to /etc/udev/rules.d/51-android.rules

  • Adding 0x1782 to ~/.android/adb_usb.ini

  • Running sudo udevadm control --reload-rules

But I still get an empty list (I'm on Linux to emphasize). I believe the issue may be that I need a spreadtrum drivers to connect to the device through adb. However I can't seem to find any spreadtrum drivers for Linux, they seem to only be available for Windows?

  • I have the exact same situation (Linux adb not seeing device with lsusb ids 1782:4001) with a phone called Accent Nubia 50k – luvzfootball Feb 16 '21 at 22:32
  • This page solved my issue: https://sites.google.com/view/bananahackers/devices/spreadtrum-based , I had to type the code `*#*#33284#*#*` on my phone for adb to list my Spreadtrum. Also, code `*#*#0574#*#*` enables a debug menu. I can now see my phone on Kaiosrt WebIDE! – luvzfootball Feb 16 '21 at 23:00
