# cannot connect to Seeker using usb: adb devices not found Source: https://forum.modalai.com/topic/1468/cannot-connect-to-seeker-using-usb-adb-devices-not-found Category: General Questions (https://forum.modalai.com/category/2/general-questions) Posted: 2022-10-19 07:08:47 UTC by ahmed-mustahid Replies: 7 · Views: 1783 ## ahmed-mustahid · 2022-10-19 07:08:47 UTC I was trying to write a python script to automate the image flashing (using install.sh file proveided inside voxl_platform3.8) and package installation processes. I stopped the process installation process before completing and after this, adb could not find the device anymore. Previously, adb could always find the device. The python script for installation: ``` In [3]: p = subprocess.Popen(['./install.sh'], cwd="/home/ahmed/work/modalAI/voxl_platform_3.8.0-0.7/", s ...: tdin=subprocess.PIPE, universal_newlines=True,shell=True) [INFO] adb installed In [4]: [INFO] fastboot installed ----Starting System Image Flash---- This process will completely wipe your VOXL's file system but will preserve the /data/ partition which contains things like calibration, wifi config, and docker images. you can optionally wipe the /data/ parition, although we encourage you not to unless you have a good reason. 1) preserve(recommended) 2) wipe In [4]: p.communicate(input="1") [INFO] Rebooting into fastboot...

You will need to unbrick it by following the unbricking procedure which you've found. For your Seeker, the fastboot switch is on the back of the Voxl-Cam. There should be a small slot from which you can flip the switch on and off. ![Voxl-Cam Fastboot Switch Location.jpeg](https://forum.modalai.com/assets/uploads/files/1666192892907-voxl-cam-fastboot-switch-location.jpeg) ![0_1666193766215_Seeker Fastboot Switch Location.jpeg](Uploading 100%) ## Reply by Adrian Hidalgo (ModalAI staff) · 2022-10-19 15:44:04 UTC ![Seeker Fastboot Switch Location.jpeg](https://forum.modalai.com/assets/uploads/files/1666194238678-seeker-fastboot-switch-location-resized.jpeg) ## Reply by ahmed-mustahid · 2022-10-24 01:27:08 UTC (in reply to Adrian Hidalgo) @Adrian-Hidalgo Thank you for the reply. Is it possible to switch it on **without disassembling** the seeker ? I have tried flipping the switch that you have shown in the image from outside the green cover. There was no **click** and `sudo fastboot device` was showing only `< waiting for any device >`. 1. Is there any specific tool or some specific way to flip the switch ? Does it make a **click** when flipped ? 2. Is it not possible to flip the switch without disassembling the device ? If so, would you let me know the tools with which I can disassmble it? Thank you ## Reply by tom (ModalAI staff) · 2022-10-24 16:18:31 UTC @ahmed-mustahid When you power and plug in your Seeker to your host PC what do you seen in `lsusb`? Does a new device appear? That would be the place to start to ensure your host machine is seeing the VOXL. ## Reply by Adrian Hidalgo (ModalAI staff) · 2022-10-24 20:39:01 UTC @ahmed-mustahid The switch should be able to be flipped without taking the Voxl-Cam off of the Seeker. The switch doesn't make any noise when it's flipped. You can use an angled spudger tool/ scratch awl/ or flat-tipped screwdriver. ## Reply by ahmed-mustahid · 2022-10-25 07:12:00 UTC (in reply to tom) @tom I have tried the following steps, but still adb could not find the device 1. I can see it using `lsusb | grep Qual` ``` ➜ work lsusb | grep Qual Bus 003 Device 006: ID 05c6:900e Qualcomm, Inc. QUSB__BULK ``` 3. ``` ➜ work cat /etc/udev/rules.d/51-android.rules SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="900e", MODE="0660", GROUP="plugdev", SYMLINK+="voxl%n" SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="d00d", MODE="0660", GROUP="plugdev", SYMLINK+="voxl-fastboot%n" ``` 4. ``` sudo service udev restart ``` 5. ``` ➜ work adb kill-server && adb start-server * daemon not running; starting now at tcp:5037 * daemon started successfully ``` 2. adb still could not find the device ``` ➜ work adb devices List of devices attached ``` 3. fastboot could not find it either ``` ➜ work sudo fastboot device < waiting for any device > ^C ``` 4. just to try out, I made the `SYMLINK+="voxl-fastboot%n"` identical to that of `SYMLINK+="voxl%n"` and repeated the above steps. ``` ➜ work cat /etc/udev/rules.d/51-android.rules SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="900e", MODE="0660", GROUP="plugdev", SYMLINK+="voxl%n" SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="900e", MODE="0660", GROUP="plugdev", SYMLINK+="voxl-fastboot%n" #SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="d00d", MODE="0660", GROUP="plugdev", SYMLINK+="voxl-fastboot%n" ``` But adb could not recognise the device this time either. Is there any other way that I can use to make adb recognise the device? ## Reply by tom (ModalAI staff) · 2022-10-25 17:38:51 UTC @ahmed-mustahid Unfortunately the "QUSB_BULK" mode that your VOXL is enumerating in cannot be fixed by our unbricking process and will have to be sent in for an RMA.
