As far as I know, NKRO USB keyboards could work in two modes: "Legacy" a= nd "Bitmap/NKRO". HID (and each USB Keyboard is HID device) is very flexible standard, and= it allows several ways to report pressed/released buttons: as event with= 8 modifier keys and up to 6 "simple" keys per event, or by transferring = bitmap with bit for each button (pretends that all buttons are modifier o= nes, which allows NKRO). "Standard" events could have only 6 different keys reported due to packe= t size constrains. But this way was historically first and "standard" key= boards work this way to this day. "Bitmap" reporting could transmit any state of keyboard with as many pre= ssed keys as there are keys total (NKRO!), but requires additional suppor= t from drirver. NKRO keyboards start in "Legacy"/"Boot" mode because many BIOSes/EFI can= not understand "bitmap" reporting. Conditions to switch to "bitmap" repo= rting are different for different NKRO keyboards. You could read more here: https://www.devever.net/~hl/usbnkro Looks like, FreeBSD HID/kbd driver has problem with "bitmap" reporting a= nd this keyboard switch to NKRO mode after boot regardless. I've CC: this message to usb@ mailing list, as it looks like USB problem= on FreeBSD side, in HID driver. --=20 // Lev Serebryakov --eOlllRxVLdgo3hThzTOYzDRWUJRlatvRf-- --vgoPU7rZ7JpA3aQuGfWGBGzI0bbZfDqxl Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE+W0coLX0MYtnSzMK6rA8WL/cR48FAl8NwzBfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEY5 NkQxQ0EwQjVGNDMxOEI2NzRCMzMwQUVBQjAzQzU4QkZEQzQ3OEYACgkQ6rA8WL/c R49cYRAAy8udW2K8s+wm8jNGf/+tV+l97yan0fnNcgeg1z97JLQM9bM83yWGjpmx +UHJgs8M75NaHOjplSUApzsjFDT3ZOpMI+fgjnujR96S1d1GUiOC44LK+UlnHY0e iChHHPI9/D01f5EhHIs7Z2ScPLFJ77omZmhP+PUlFM/bqtTAilIHg/PEVCI9gqA1 pOhvRmorIimLtulPT5iVfngeCuOgQaNvovNsE++Pcfe3qeXubxQ4UzvtaDsRwsRl Li5lZ8TVQh72TQ7v1yb1D7UL5NGox7RnmAZniICPHl+xWNzjAA9hQ+F4yrYibtk+ sJikjBpHI4qdA1KzIH0IrWEACTSY7YglPvTMignc2Dor2fkuRXaOnbU1k5JYSMH0 0VW6TJsxyGAZKHuzI2f2BuYtoa0b41k7yPYqPCTIIk7BfaN0lgBaQeFmq3py4ruB zDynWpjh0C6737JRbc2xtjKHz8YepfiuJNFMRpPSiNBSn1Pl9ItJDzIGiebgpQ4c 5ZIMyqmiezQXQZ093ivY8rOq43ZoxHMSXlcTPcpEr8vRiB4nxP0SY30PqSQ5yXJu BF1ZdKneQsVzzkTDs+/ZyTrz2JehArhPy+UM4We2+LVYvsQR0i6BQZJA1yaUP/iF bSMmdjp9ys+HG3pN9CYnl2KrDN65W7Xb5LKk0knTekelQQJIqZY= =nRow -----END PGP SIGNATURE----- --vgoPU7rZ7JpA3aQuGfWGBGzI0bbZfDqxl--
