Re: How do I boot my RPi4 from an SSD?

Not really sure what's going on with that SSD, but if returning it is an option, you might be better off doing that. I use a SATA SSD with a USB 3.0 to SATA-III adapter based on the ASMedia 1153E chipset. Been using similar adapters on Pi computers since the 3B model and most have worked well for me...

Re: Connect to monitor through USB-C hub

The USB-C power port on a Pi is just a plain ol' USB 2.0 port. It does not have any other USB-C functionality (no audio, no video) but it does have data, so you can use it as an extra USB 2.0 port (with the appropriate overlay).

Re: How do I boot my RPi4 from an SSD?

You could have a bum SSD. Have you used it before (or was it a new purchase)?

If you write RPiOS to an SD card or USB flash drive (other than your SSD) and connect it to your Manjaro PC can it read and mount those?

Re: How do I boot my RPi4 from an SSD?

Try sudo mount -t vfat /dev/sdb1 /media/usbdrive

If that doesn't help, install gparted and see what it can tell you about the SSD.

Re: Several Minecraft Server's

As imgamingbear said, use different port numbers for each server (I have a couple of different servers running that way, and like you want to do one of mine is vanilla and the other is an older one running Spigot).

Yea, the 2 second default timeout seems short but it's supposedly based on the USB spec (haven't looked that up myself). The Pi3 had the same 2 second default.

Could be different things. These are some things to check...

  1. Your USB drive could be taking too long to get ready.
  2. Identical PARTUUID on the card and USB drive.
  3. Third party OS incompatibility.
