If you are a beginner to Raspberry Pi I advise NOT using the USB boot features - stick to SD cards - they will work fine for you just as they have done for the last 8 years for the majority of users.
The beta firmware and bootloader for USB mass storage boot on Pi 4 are now available.
Documentation and setup instructions are on the bootloader configuration page, please read it.
This is a beta release. If you aren't already comfortable with manual firmware updates then please wait until this is available in a standard release. It won't be very long!

General interoperability reports should be posted on the forums. The rpi-eeprom issue template has been updated to indicate what sort of logs will be required in bug reports.
Mini-HOWTO if you have a USB card reader:-
- Burn Raspian to a fresh SD card using the Raspberry Pi Imager.
- Select beta bootloader and use rpi-eeprom-update -d -f to update it (the new configuration settings are required)
- Reboot to update the bootloader
- Eject the SD card and boot using USB card reader instead of direct SD boot.
N.B. The 'pass' criteria for the beta is no regressions and enough USB pen-drivers, SSDs + mouse + keyboard + powered hub working i.e. usual desktop configurations. Bugs with more complicated setups will be fixed in the usual incremental releases.
Anyway, code released, time to run (literally). Have fun!
