Does the X825/X829/X855/X856/X857/X862/X872/X835/X832 support USB boot?

Network and USB boot
Support for these additional bootmodes will be added in the future via optional bootloader updates. The current schedule is to release network boot first, then USB boot.

OK, Raspberry Pi Foundation release BETA version to support USB boot on May. 2202, please refer to Pi 4 Bootloader Configuration, TESTED!

More detail please refer to and

But USB mass storage boot is available on Raspberry Pi 3B, 3B+, 3A+, and 2B v1.2 only.

I managed to use this board for Homeassistant ( and used the beta v5.1 HassOS that supports SSD booting. I can confirm this is working with this board, however i get Kernel Messages about UAS mode. After applying usb.quirk as describerd here (https://www....php?t=245931) there are no errors anymore. How well is UAS mode implented in youre device?

Exactly the same here. I had to apply quirk in order to avoid this messages. I'd like to know a SSD drive fully supporting UAS mode
