@xmiinc Can you confirm what you see on this location in Finder. You’ll need to ‘show invisible files’.
@xmiinc You might also try brew reinstall libusb from terminal.
Sorry for the delay in responding…
Hmm…after searching for awhile (and not finding the directory) I came across this from the 'net:
If this is a booted out-of-the-box M1, without a time machine migration, then there may not be a /usr/local folder by default, and you will have to make one. You won’t see the contents of /usr/local in the Finder unless you enter that path in the Finder’s Go to Folder (shift+command+G) dialog. Apple includes Apache in macOS 11.*, so unless there are specific features that you must have from a newer version, adding it from brew might be unnecessary. If you are running homebrew 3.0.0 or later (advised) on an M1 Mac, it wants to put things in /opt/homebrew, which would explain why you were surprised about the empty /usr/local — where it would have placed things on an Intel Mac.
In my case, I have the /usr/local directory and, as it was a tm migration it has files…but not the ‘opt’ directory and therefore no /libusb/lib/…until I searched using Terminal and found the following lines:
/opt/homebrew/lib/libusb.dylib
/opt/homebrew/lib/pkgconfig
/opt/homebrew/lib/pkgconfig/libusb-1.0.pc
/opt/homebrew/lib/pkgconfig/libusb.pc
/opt/homebrew/lib/libusb-1.0.dylib
/opt/homebrew/lib/libusb-0.1.4.dylib
/opt/homebrew/lib/libusb-1.0.0.dylib
/opt/homebrew/lib/libusb.a
/opt/homebrew/lib/libusb-1.0.a
/opt/homebrew/lib/.keepme
/opt/homebrew/opt
/opt/homebrew/opt/cowsay
/opt/homebrew/opt/dfu-util
/opt/homebrew/opt/libusb-compat
/opt/homebrew/opt/cowthink
/opt/homebrew/opt/libusb
…which would explain why the installer reported a successful installation of the tools, but not in a location that the installer expected in order to update the firmware of the Kordbot. That leads me to think maybe I should create an empty /opt directory in the /usr/local directory and re-run the installer? Does that sound plausible that it would work by designating the destination directory and letting the installer do it’s thing? Thanks for your suggestion, rozz3r, I never would’ve gotten this far without it!
@xmiinc It’s worth a shot. If it doesn’t work, private message me, I may have something else you can try but I don’t want to bog this thread down too much.
Trying to update the firmware but the pc says the STM Bootloader is not right for the PC. I tried both x64 and x86 but neither work. Its an Intel Celeron machine…‘The location you specified does not contain any driver software installation files.’ Update got the STM driver from another website ST Microelectronics and was able to update the firmware. Once the PC has finished its 125th update I’ll reformat the SD card and try again as I’m getting [sdc] no update files…tried 4gb, 16gb and 64mb. None of them work. The boot screen looks like this
HELP!
Ordered new Sandisk Extreme SDHC UHS-1 Card 16gb from Amazon and success! Kordbot loaded the firmware and is now running again - hurray!

@Keith.holmes Can you please link me to the exact card you used?
