ℹ️ Resolved: Raspberry Pi 4B Rev 1.4 may need EEPROM bootloader update for HAOS …17.2 compatiblity
---
Older versions of Raspberry Pi 4B (Rev 1.4) may be using an old EEPROM bootloader which results in USB devices becoming unavailable after the update to HAOS 17.2. While reverting to 17.1 works around the issue, it is **strongly recommended to perform update of the bootloader**.
## Summary
According to the current reports and logs, this issue appears to affect only **Raspberry Pi 4 Model B Rev 1.4** boards.
On affected systems, the USB controller can fail to initialize after the update to HAOS 17.2, which makes all USB devices unavailable. Affected boot logs usually contain:
```txt
xhci_hcd 0000:01:00.0: can't setup: -110
```
Reverting to 17.1 works around the issue, but it is **strongly recommended to update the EEPROM bootloader**.
## How to check if my board is affected
You can confirm this in either of these ways:
- Check the early boot host logs for:
```txt
Machine model: Raspberry Pi 4 Model B Rev 1.4
```
- Check `cat /proc/cpuinfo` (e.g. in Terminal & SSH App) and look at the `Model` value. For example:
```txt
$ cat /proc/cpuinfo
...
Model : Raspberry Pi 4 Model B Rev 1.4
```
## Workarounds
If you need to restore USB before updating the bootloader, you can revert to the previous version or 17.1 using one of the following commands:
- `ha os boot-slot other`
- `ha os update --version 17.1`
## How to update the bootloader
The best long-term fix is to update the Raspberry Pi EEPROM bootloader.
If you have access to the device's console (meaning you can attach an HDMI display and a keyboard) or have the [developer SSH](https://developers.home-assistant.io/docs/operating-system/debugging/#enabling-ssh-access-to-the-host) enabled, use the `rpi-eeprom-update -a` command followed by a reboot. **Note that the SSH terminal apps available from the store can't be used to run this command.**
Alternatively, if you can't use the above method, see the [pinned comment](https://github.com/home-assistant/operating-system/issues/4627#issuecomment-4206823784) for the method using Raspberry Pi Imager and a spare SD card.

<details>
### Describe the issue you are experiencing
**Describe the issue**
After updating Home Assistant OS on a Raspberry Pi 4B, the entire USB subsystem stops working. No USB devices are detected at all — not serial adapters, not storage, not HID devices.
- `/dev/ttyUSB*`, `/dev/ttyACM*` do not exist
- `/dev/serial/` directory is entirely absent (no `by-id`, no `by-path`)
- No USB devices appear under Settings → System → Hardware
- Plugging in any USB device after boot produces no kernel events
- Host logs show no xHCI host controller initialization
**Attempted mitigations — none resolved the issue**
- Multiple reboots and full power cycles
- Restoring multiple full backups
- Moving devices between USB 2.0 and 3.0 ports
- Testing with multiple known-working USB devices
- Downgrading HA Core
- Downgrading HA OS using `ha os boot-slot other`
- Upgrading HA Core and OS once again
**Edited: workaround using ha os update --version 17.1 does work for now!**
From my research it seems the USB host controller (xHCI) fails to initialize at the kernel level.
### What operating system image do you use?
rpi4-64 (Raspberry Pi 4/400 64-bit OS)
### What version of Home Assistant Operating System is installed?
17.2
### Did the problem occur after upgrading the Operating System?
Yes
### Hardware details
RPI 4B works on an SD card that I flashed a few years back.
USB devices used in my case are a Zigstar stick v4 for Z2M and a P1 port measurer (DSMR FTDI_FT232R_USB_UART).
### Steps to reproduce the issue
1. Run HAOS on Raspberry Pi 4B
2. Update to latest stable HAOS + Supervisor (supervisor-2026.03.3)
3. Reboot
4. Observe complete absence of USB devices
### Anything in the Supervisor logs that might be useful for us?
No relevant supervisor logs.
### Anything in the Host logs that might be useful for us?
This might be relevant from Z2M:
