I have uninstalled Saleae software and drivers (just to have everything clean) and then I have installed WinUSB (v6.1.7600.16385) via Zadig (see attached screenshot). I run PulseView and got the same error (see below for transcript). On 2020-01-10 10:50, soe...@apelpie.net wrote: > Yes, you can do that.

Thanks for pointing that out. It turned out that PulseView was trying to locate a different firmware: sr: backend: libsigrok 0.5.1/5:0:1 (rt: 0.5.1/5:0:1). sr: backend: Libs: glib 2.44.1 (rt: 2.44.1/4401:1), libzip 1.5.1, libserialport 0.1.1/1:0:1 (rt: 0.1.1/1:0:1), libusb-1.0 1.0.20.11003-rc3 API 0x01000104, libftdi 1.2. sr: backend: Host: x86_64-w64-mingw32.static.posix, little-endian. ... sr: hwdriver: Scan found 0 devices (saleae-logic-pro). sr: ezusb: uploading firmware to device on 3.15 sr: ezusb: setting CPU reset mode on... sr: resource: Attempt to open '...\PulseView\share\sigrok-firmware\saleae-logic16-fx2.fw' failed: No such file or directory sr: saleae-logic16: Firmware upload failed, name saleae-logic16-fx2.fw. sr: hwdriver: Scan found 1 devices (saleae-logic16). sr: device: saleae-logic16: Opening device instance. sr: saleae-logic16: Firmware upload was not needed. saleae-logic16: Failed to open device: LIBUSB_ERROR_ACCESS. sr: saleae-logic16: Unable to open device. Notifying user of session error: "generic/unspecified error" while correct (or, let's say, one that is present) is '...\PulseView\share\sigrok-firmware\fx2lafw-saleae-logic.fw' I got confused... Where to get saleae-logic16-fx2.fw from? It is not a part of binary download [1], right? While trying to locate it I found the issue #650 which looks to be the same as I experience.

WinUSB driver was installed by PulseView, right? So I decided to install libusb driver as that comment advises. However instructions on [4] generally contradict with comment #25: > Currently, this means installing *one of* Microsoft's WinUSB, libusb-win32 or > libusbK drivers. > Use the most recent version of Zadig, an Automated Driver Installer GUI > application for WinUSB (recommended), libusb-win32 (not working well, not > recommended) and libusbK (only if you hit WinUSB limitations). Now I am lost what to do next... Thanks in advance for help.
