Analog Discovery 2 stopped working with Raspberry Pi 4

[Chuankun]

Hi,

 I had my Analog Discovery 2 working with Raspberry Pi 4 before. However, it stopped working today after me executing "sudo reboot" on the Raspberry Pi while the Analog Discovery 2 was connected and running. 

 I checked that the Analog Discovery still works fine on other computers (Windows 10, Ubuntu 20.04). I tried different USB ports / cables on the Raspberry Pi, and had no luck. The Raspberry Pi is powered from the original power supply, and I am now connecting only the Analog Discovery, so there should be no power issue. 

I ran "usb-devices" on the Raspberry pi to see if there is something. However there are no differences with the Analog Discovery connected or not. I listed the output below anyway if this might be helpful.

The Raspberry Pi USB ports seemingly are still working. I can read my HDD portable drive on it without any problem. I purged and reinstalled the following packages on my Pi, but still couldn't get connected. 

pi@raspberrypi:~ $ dpkg -l | grep digilent
ii  digilent.adept.runtime                  2.21.2                              armhf        Digilent Adept Runtime
ii  digilent.adept.utilities                2.4.1                               armhf        Digilent Adept Utilities
ii  digilent.waveforms                      3.14.3                              armhf        Digilent WaveForms

I guess I should use the same version for the Waveforms and adept packages. However I can't find the same version number on the webpage. The earliest version of Waveforms that I can find is 3.0.16 while the most recent version of adept runtime is 2.21.2. So I just installed the latest version anyway...

 

Any suggestions on how I can proceed? Thanks a lot for your help!

Could also be a Kernel-related issue?

pi@raspberrypi:~ $ uname -r
5.4.79-v7l+

Hi @Chuankun

Does the lsusb detect the AD2 (FTDI device)?
Please also try running: python /usr/share/digilent/waveforms/samples/py/Enumerate.py

Hi @Chuankun,

I had a similar problem. I have just bought and updated a Raspberry Pi 4 B and installed Adept Runtime 2.21.2, Adept Utilities 2.4.1 and Waveforms 3.14.3 without any issues.

When I run Waveforms from the applications menu its Device Manager doesn't see my AD2, despite it's connected to one of the USB 3.0 ports.

I tried both lsusb and sudo lsusb, and there was a difference, the latter showed more devices, so I also tried to run Waveforms from the command line sudo /usr/bin/waveforms, and it started to work!

(I probably made a mistake when I installed the Digilent packages as root, and not as the user pi.)

Thanks! Sorry I have just used the Analog Discovery 2 on a PC instead recently, until it broke somehow... Thank you very much for the suggestions!  I unfortunately cannot test your suggestions unless I can repair it or get a new one?
