Hi, I am new to pulseview and logic analyzers for that matter. I've uploaded the latest firmware to a rp2040 zero board but is not detected by pulseview and the "choose driver" dropdown is empty.

I need to install something else?

lsusb shows the device conected as:

Bus 003 Device 011: ID 16c0:27dd Van Ooijen Technische Informatica CDC-ACM class devices (modems)

using Ubuntu 23.04

Hey @darkbox Could you please run ls /dev/tty*?

The output is:

I guess it is this one: /dev/ttyACM0

Is this /dev/ttyACM0 disappear when disconnecting Pico? Also could you try following command: sigrok-cli -d ols:conn=/dev/ttyACM0 --scan?

yes

Also could you try following command: sigrok-cli -d ols:conn=/dev/ttyACM0 --scan?

sigrok-cli -d ols:conn=/dev/ttyACM0  --scan
Driver ols not found.

I've been looking for a solution on the Sigrok web but didn't find anything related. For what I understood, all the drivers are on share library called libsigrok which looks like is installed already. This are the packages installed on my system (apt list --installed | grep "sigrok"):

libsigrok4/lunar,now 0.5.2-4 amd64 [installed]
libsigrokcxx4/lunar,now 0.5.2-4 amd64 [installed]
libsigrokdecode4/lunar,now 0.5.3-4 amd64 [installed,automatic]
sigrok-cli/lunar,now 0.7.2-1 amd64 [installed]
sigrok-firmware-fx2lafw/lunar,lunar,now 0.1.7-1 all [installed]
sigrok/lunar,lunar,now 0.3 all [installed]
pulseview/lunar,now 0.4.2-3 amd64 [installed,automatic]

Update: I've tested it in Windows 10 and works. So maybe there is some problem with the builds of Pulseview for Ubuntu. Meanwhile I'll use Windows and if I found a solution in the future, I'll post it here.

I had the same problem on Ubuntu and Manjaro but it works if run pulseview with sudo: sudo pulseview The problem is the permission to acces to /dev/ttyACM0. https://stackoverflow.com/questions/49063139/why-do-i-need-to-execute-sudo-chmod-arw-dev-ttyacm0-command-again-after-every

I have the same issue even with sudo :

sudo sigrok-cli -d ols:conn=/dev/tty.usbmodem_ula_1 --scan
Driver ols not found.
