ADB devices not found

marian

Hi, for the same voxl cam I ordered, i tried to use adb to connect to it and doesn't work. I tried via un Ubuntu client and via my mac too.

The answer is always like this:
% ./adb devices
List of devices attached

Via Windows (where i use an ubuntu client) I see the devices connected on the usb port, but on linux the command adb doesn't see it.
Via Mac I don't see at all the devices connected.

I use the power module delivered with the voxl package and a 4s battery to power it.

Please advice how to proceed.

I see the device when I run lsusb on the ubuntu client, but not when I run the adb devices command as below:

marian@RM:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 05c6:901d Qualcomm, Inc. APQ8096-MTP _SN:4549C070
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
marian@RM:~$ adb devices
List of devices attached

marian@RM:~$

@marian Does it show up with fastboot devices perhaps?

marian

@tom Thank you for your reply.
No, it doesn't.

I verified the link and it's fine as per below:

On Windows
PS C:\WINDOWS\system32> usbipd wsl list

@marian Were you able to connect to the VOXL-Cam via ADB in the past? Or have you been having these issues out of the box?

marian

@tom I have being issue out of the box, it never connect via adb

tom

@marian And using this same PC, are you able to ADB onto a different VOXL-Cam?

marian

@tom I have only one voxl-cam

tom

@marian So is SSH working then? I see that you've done some work with this VOXL Cam already based on your post history?
Or were you connecting directly to the Flight Core via JST to USB?

marian

@tom Yes, the ssh and connecting the flight core via jst to usb is working.

When I bought the voxl-cam I understood that came calibrated and ready to use. But, as I used it on a custom frame the sensors like accelerometer, compass and gyroscope are not calibrated.

I used it on the frame on the same way like seekers (of course, I needed it to adapt the /etc/modalai/extrinsics.conf file for my configuration), but

whenever I use a GPS with compass (as M8N u-blox) I can't calibrate the compass, it will see a different position instead of the position the drone really is, it is finishing the calibration anyway, but after reboot it will ask me again to re-calibrate the compass
whenever I used it for indoor navigation, so GPS and compass disabled, I calibrate the accelerometer with ROTATION-NONE as per modalai documentation,then once I have the local position on, the QGC tell me that I have a roll failure detected and, of course, can't proceed with arming.

So, basically I can't use at all the voxl-cam

@marian Okay that is good that at least ssh is working so the board should be functional. I wonder if it is some sort of user privileges issue that ADB isn't coming up. What if you do sudo adb devices? And what if you remove that android rules file: sudo rm /etc/udev/rules.d/51-android.rules and reboot your PC? I'm not sure that file is necessary.

For those other questions, I would open a new forum topic so that the whole team can get eyes on it.

marian

@tom The results are the same even if I use sudo or I remove the 51-android.rules

tom

@marian Did you reboot after removing the android-rules file?

tom

@marian We may have to take a look at your hardware in house, checkout our RMA info here: https://modalai.com/rma

marian

@tom yes, I rebooted the pc

marian

@tom In terms of RMA, can we try to have a remote diagnostic? I'm far a way from US ...

tom

@marian Have you been able to ADB in to any other VOXL devices on this PC in the past? From what I see in your lsusb output everything looks correct. I'm wondering if there's an issue with your ADB install

tom

@marian Here is what a working VOXL looks like on my machine running Ubuntu 18: Bus 001 Device 068: ID 05c6:901d Qualcomm, Inc. We have others at the company who use 20 so that shouldn't be an issue

@tom I see the same things, but stiill the adb or fastboot commands don't see my device. I tried with two different laptops, and the problem is the same as per images below:
