forgot to mention that I changed the USB cable, but the bug remained and lsusb and other messages remained the same. You probably failed to install the udev rules to the correct location. To check if it's udev, you can try running PV or sigrok-cli as root. If the device is recognized there, you need to install the udev rules (see https://sigrok.org/gitweb/?p=libsigrok.git;a=tree;f=contrib) and force udev to reload the rules (a reboot works, too). Nicolas, do you have an update for us? Yes, sorry I was away from home for a while. The installation of udev rules (which I don't very much understand !) solved the problem. Great, many thanks for the answers. Hello I'm trying to do the same thing as Nicolas, to use Pulseview on Rpi3 and I think I encounter the same problem. I'm working on this from several days, I've tried different things like: updating fx2lafw again and again in different ways, Trying even to build the entire thing on VMBox with Raspbian, I also found a script to compile and install PulseView on Ubuntu Linux (https://gist.github.com/onetransistor/3e12e2e3a900b1110c111a0efda6ee4a) but unfortunately because I have only 1 Gb Ram I cannot pass the Pluseview build step. I found some Snap thing build related to the sigrok and use that build in different ways and somehow I manage to make the Pulseview app to work but in the end I get the same error : fx2lafw: Failed to open potential device with VID:PID 0925:3881: LIBUSB_ERROR_ACCESS. If you have any advice on how to proceed or have any idea I will be very grateful. Thanks, Marian! |
