Created attachment 612 [details] sigrok-cli log Pulseview is not able to connect to a Rigol 1054Z over USB, even though the USB device has +uaccess permissions. Applicable release versions: Fedora 31 libsigrok: 0.5.2 pulseview: 0.4.1 sigrok-cli: 0.7.1 Additional info: sigrok-cli log shows a USB timeout error, then a degmentation fault (will attach log)
This looks like the same problem as bug #1272.
On the version that you have, I think you should also be able to work around this by adding "-d rigol-ds" to specify the driver.
I understand this was reported against an older software version. Does it reproduce with recent software? Does the combination of -D and -d succeed as a workaround? The "ECHO-TEST" literals strongly suggests that the issue got fixed long ago.
Hi, please try to reproduce with git master as of today, a few fixes have been merged which might affect this. The segfault should be gone, and a simple "sigrok-cli --scan" works fine for me (DS1054Z, attached via USB) as well as a basic PulseView acquisition.
