What are the units for sysctl.hw.usb.timings?  Seconds?  Milliseconds?

I ran sysctl hw.usb.timings and got

hw.usb.timings.port_reset_delay: 50
hw.usb.timings.port_root_reset_delay: 250
hw.usb.timings.port_reset_recovery: 250
hw.usb.timings.port_powerup_delay: 300
hw.usb.timings.port_resume_delay: 40
hw.usb.timings.set_address_settle: 10
hw.usb.timings.resume_delay: 250
hw.usb.timings.resume_wait: 50
hw.usb.timings.resume_recovery: 50
hw.usb.timings.extra_power_up_time: 20

I checked man sysctl, sysctl.conf, loader.conf and more, no clue.

I could guess milliseconds, but maybe 1/100-seconds?

I get console messages about keyboard and mouse being disconnected when that is not true, for both FreeBSD and NetBSD; also wlan under FreeBSD.

So I would like to increase these times by a factor of 100, if it is milliseconds.
