Hi mitcdavi

Have your Ubuntu machine connected other Qualcomm platform? Just wonder if adb , fastboot had been installed.

You can do  things:

1. Capture boot up log from debug port and make sure device booted up successfully

2. Tried to connect RB5 to windwos machine, and check ports from device manager and see if there are adb port there.

Thanks

Kevin

Trying to connect qualcomm 9206 device.  Yes I connected the platform to my ubuntu machine and adb, fastboot are both installed on my machine and on the rb5.  Wondering if this is an rb5 issue as I wasn't able to connect a smart phone using adb either.  Appreciate any suggestions

There is an ADB Interface under universal serial bus devices when I connect RB5 to windows.

Hi mitcdavi

If you connected  RB5 to Windows PC, in device manager,  check the Ports (COM & LPT)

You should  see :

1. Qualcomm HS-USB Android DIAG 901D (COMM11)

2. USB Serial  Port

If you could not see Android port, you could not ADB devices.

Have you green LED light on RB5?

Please try these steps:

1. Unplug USB and Power connection

2. Plug Power  and USB connection

3. Press Power on button and hold for 5 seconds.

4. catpture the boot-up log and send to use.

Let us know your result.

Thanks

Kevin

Hi mitcdavi,

We are checking the issue regarding connecting adb devices to RB5, with our hardware engineers. Will get back to you with an answer as soon as we figure something out.

Thank you

Hi mitcdavi,

Please run this command before starting adb command
