Any advice on Thunderbolt equipped display?

[ckunte]

Any advice on connecting two (Thunderbolt USB-C connector equipped) computers (HP 830 G5 and 2020 Mac Mini) to a single display with two thunderbolt ports (LG 24MD4KL-B)?

Here's what I did but did not succeed with the instructions in README:

1. Installed pyusb with python3 -m pip install pyusb

2. With a mouse connected to the UGREEN hub's central port, I ran the following script to get vendor ID and product IDs

   #!/usr/bin/python
   import sys
   import usb.core
   # find USB devices
   dev = usb.core.find(find_all=True)
   # loop through devices, printing vendor and product ids in decimal and hex
   for cfg in dev:
     sys.stdout.write('Decimal VendorID=' + str(cfg.idVendor) + ' & ProductID=' + str(cfg.idProduct) + '\n')
     sys.stdout.write('Hexadecimal VendorID=' + hex(cfg.idVendor) + ' & ProductID=' + hex(cfg.idProduct) + '\n\n')

   For this, I got the following output for my barebones Logitech M90 mouse:

   Decimal VendorID=1133 & ProductID=49271
   Hexadecimal VendorID=0x46d & ProductID=0xc077

3. Followed the rest of the process described in the README.

hex ids should be 4 hex characters I believe

try looking at the logs when you run. You can find where logs are in this issue: https://github.com/haimgel/display-switch/issues/6

Thank you. I fixed it to "046d:c077".

On MacOS Catalina, I get:

com.apple.xpc.launchd[1] (dev.haim.display-switch.daemon[419]): removing service since it exited with consistent failure - OS_REASON_EXEC | Gatekeeper policy blocked execution

I then explicitly allowed it under Security and Privacy.

On Windows 10, the application display_switch.exe does not run perhaps because I am a locked user. I suppose it is too much of a stretch for end users like me with handicap(s) like these.
