Hi Val and WeatherCat Davis users,
Just wondering if anyone has come across this before and found a solution?
I upgraded my hard drives on my iMac and did a fresh install of Mavericks. Everything went well with no issues. However, every time I restart the system (programmed every day) Weathercat fails to find my Davis Vantage Vue console as it is finding two instances of the USB to Serial link port '/dev/cu.SLAB_USBtoUART' and 'cu.SLAB_USBtoUART1'. I have to manually select the second for Weathercat to function.
I have reinstalled the latest Silicon Labs drivers.
Any ideas how I can correct this?
Hmm, that dredged up an old memory about where those drivers are stored. When I went to that location I had a surprise of my own!
There is a file associated with the drivers and you'll find it at this location on your hard drive:
/System/Library/Extensions/That's using UNIX filesystem conventions.
When I check out this location I also find two files -
eek!/System/Library/Extensions/SiLabsUSBDriver.kext
/System/Library/Extensions/SiLabsUSBDriver64.kextThe file
SiLabsUSBDriver.kext has a much older modification date and I'm guessing that's an unused 32 bit version of the driver, but it is surprising to still find it on my system nonetheless.
For your predicament, the most user-friendly solution would have been an uninstaller. Alias, I just checked, Silicon Labs doesn't provide an uninstaller. So if you find yourself with two files you'll need to remove one manually.
I'm not entirely sure, but my best guess would be to reboot your Mac in "safe mode" (hold down the shift key.) Then go to the folder noted above and drag the offending file to the trash. You might not be able to delete the file until you reboot, but in safe mode it shouldn't have loaded the extension.
Just to be safe, I would suggest that you trash anything that looks like
SiLabsUSBDriver.kext and then install a fresh copy of the driver using the latest installer from the Silicon Labs website. That way you avoid any contamination from the previous files and the Silicon labs installer would have a clean slate to work with.
Given the oddity of this situation, definitely have a backup of your system before doing -
ANYTHING!Hope this gets you unstuck.
Cheers, Edouard
