FX2 LA (8ch) not acquiring in latest PulseView 64-bit Windows.

PulseView 0.5.0-git-3d396c8 exhibits this problem.

Log:
sr: asix-omega-rtm-cli: Cannot execute RTM CLI process: Failed to execute helper program (Invalid argument)
sr: ftdi-la: Failed to get the FTDI strings: -4
sr: usb: Failed to get libusb file descriptors.
pv: Acquisition took 0.00 s

(note, there was an FTDI lead also attached which is always present and should not be relevant to the issue.)

I did a reinstall of the driver using zadig.exe which made no difference.

If I close this new version of PulseView and run an earlier version (0.5.0-git-7e5c839) I can acquire normally.

Both versions of PulseView are installed side-by-side and I run only one instance at a time.

I've just re-opened the new PulseView to check something else and it can't even see the FX2 LA.

Comment 2 Joe Butler 2023-10-06 23:48:31 CEST

Ignore Comment 1, above. I could not open the FX2 because it was still running in a previous instance (reporting another issue elsewhere).

The bug report remains valid.

I am also affected by this bug.
