The CM4 works just fine.

If the carrierboard you're using does include USB3 support (the "official" CM4IO board does) you can enable it by adding the line: otg_mode=1 to the config.txt file that you find on the MSDOS partition of the SD-card or eMMC that you're booting from. Additional options may be needed to enable other devices on your carrierboard. For example, to enable the RTC on the CM4IO board you need to add: dtparam=i2c_vc=on dtoverlay=i2c-rtc,pcf85063a,i2c_csi_dsi This isn't in any way OpenBSD-specific; refer to the Raspberry Pi documentation instead (which admittedly isn't great).
