Installation issue on macOS Mojave with FineOffsetUSB

[Sean Timm]

I have a WS-2080 connected via USB (FineOffsetUSB) to a Mac Mini running Mojave 10.14.2.

I am receiving a driver error:

default 23:55:14.233775 -0500 Python import of driver failed: No backend available (<class 'usb.core.NoBackendError'>)

default 23:55:14.233817 -0500 Python engine: Unable to load driver: No backend available

default 23:55:14.233836 -0500 Python     ****  Exiting...

I installed WeeWX following the directions for MacOS. Two deviations were made from the installation instructions: I installed Pillow instead of PIL, and I ran pip with --user instead of sudo.

Next I installed libusb from homebrew to see if I could fix the above error. Now I get the following:

default 00:12:21.154045 -0500 kernel 002458.086826 Python@(null): IOUSBUserClientLegacy::start: missing entitlement com.apple.ibridge.control

default 00:12:21.157183 -0500 Python fousb: Unable to claim USB interface 0: [Errno 13] Access denied (insufficient permissions)

default 00:12:21.157250 -0500 Python import of driver failed: [Errno 13] Access denied (insufficient permissions) (<class 'weewx.WeeWxIOError'>)

default 00:12:21.157465 -0500 Python     ****  Exiting...

Running as 'sudo bin/weewxd weewx.conf' does not change the error messages.

It looks like Monte had a similar problem in this thread: 'version 3.3.1 on Mac OS X Yosemite "No backend available".', but I do not see that he got it working.

Any ideas?

Thanks,

Sean

Ah, I found another thread that is useful... https://groups.google.com/forum/#!topic/weewx-user/tFGnDKSXgfo

Too late to play with it tonight, but I'll try the usb branch tomorrow. Anything that I need to be aware of?

Thanks,

Sean

Matthew Wall,

I installed your "usb" branch of WeeWX. I'm still getting insufficient permissions. Are there code or configuration changes that I need to make to get it to work?

Thanks,

Sean

Put the user that is running the weewx into the dialout group?

when in doubt Google the error message you get....

See if https://forum.mongoose-os.com/discussion/1719/help-connecting-adafruit-huzzah32-to-new-macintosh helps any

I gave up and purchased WeatherCat.
