I disabled the three entries for uhci, ohci and ehci: # USB support options USB_DEBUG # enable debug msgs # device uhci # UHCI PCI->USB interface # device ohci # OHCI PCI->USB interface # device ehci # EHCI PCI->USB interface (USB 2.0) device xhci # XHCI PCI->USB interface (USB 3.0) device usb # USB Bus (required) device ukbd # Keyboard device umass # Disks/Mass storage - Requires scb= us and da and maybe this will help already. I will let you know and update the PR later the day. matthias --=20 Matthias Apitz, =E2=9C=89 guru@unixarea.de, =E2=8C=82 http://www.unixarea.d= e/ =E2=98=8E +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub --TakKZr9L6Hm6aLOc Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEXmn7rBYYViyzy/vBR8z35Hb+nREFAllV8OoACgkQR8z35Hb+ nRE0+Q//XmsMYL4u1z3SY4QairQ1KaObgEhA5sRqS68PkLQJ1gj24cyKdHXzEJaC BDSZfQoTnq0EKaPRDvtYiPuTN8apYGYwfDhjz/S24H+mwIK0U+YuL7mousdzSgOQ GQhePspJWC0PIVzTQt+VxBgeGoS//iWa5AKUVAGBHB9DtbZtNLyxK3yhElZI7ea/ 6RRGICewfxyA3VU8F1d4raU+nVKNcmtwK9gc529IPHT7/u7GdHU006rkDbXANp1c TO/LoZF2Xd8jZ6EVWi6vcnhUCf8WqFeKjU2zT9OmW9hizgjrFGCxChOwahM5pnuX YjNdD0tAn+rY6oDTq1wjm2AbG8Lb77gXrcwriozqEHGw60oY77iiGfAb9y/Vqyuh H3A3sCuepT87ee/IyiY68uOnT9uAkzYxugqk1F4izb0E8HK0sKlpkhpsQY+65o/Z 4XDPfgGtll59wWKAksNc2dX6cb8LMn9KhnmQzcGSEB4SwGcofoS0e1HGbqiC2TDQ Tb5tW17HOR/rfvSuIwZX3PwlvhGNV8w5jhR3QHmwMMF48N7AvUK5X+TRA0PU2hYi jez4Mw+s2YRAjo2OKT05m9MBONcyZMlYxbyC/FdXAPkH3l9aEdaUZElHkT+Kj/TB egfSAbvWRbP1cf81UCzm0yV7edFklunCITFuigLWHIxWMhD2Tns= =raW4 -----END PGP SIGNATURE----- --TakKZr9L6Hm6aLOc--
