Packets are 55received and transmitted over separate USB bulk transfer endpoints. 56.Pp 57The Kawasaki adapter supports only 10mbps half-duplex mode, hence there 58are no 59.Xr ifmedia 4 60modes to select. 61.Pp 62For more information on configuring this device, see 63.Xr ifconfig 8 . 64.Sh DIAGNOSTICS 65.Bl -diag 66.It "kue%d: watchdog timeout" 67A packet was queued for transmission and a transmit command was 68issued, however the device failed to acknowledge the transmission 69before a timeout expired. 70.It "kue%d: no memory for rx list" 71The driver failed to allocate an mbuf for the receiver ring. 72.El 73.Sh SEE ALSO 74.Xr arp 4 , 75.Xr netintro 4 , 76.Xr ifconfig 8 77.Sh HISTORY 78The 79.Nm 80device driver first appeared in 81.Fx 4.0 . 82.Sh AUTHORS 83The 84.Nm 85driver was written by 86.An Bill Paul Aq wpaul@ee.columbia.edu . 87.Sh BUGS 88The 89.Nm 90driver does not accumulate ethernet collisions statistics because the 91Kawasaki firmware does not appear to maintain any internal statistics. 92
