Dear All, I have Gigabit USB NIC, Buffalo (Melco Inc.) LUA3-U2-AGT. That NIC use AX88178. I use that NIC with CardBus USB 2.0 port. http://www.avlab.com.tw/usb/1005_0004_000cx.htm
But I often could not use that NIC with CardBus USB 2.0 port. With Another USB port(USB 1.1), I always use this NIC(but poor performance) Pleae let me know to how to fix this problem. [NG Steps] (with CardBus USB 2.0 port, about 9 times NG, 10 times tests) 1. Insert USB NIC. 2. This USB NIC was not probed USB 2.0, only USB 1.1[NG] # usbconfig ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.1: <OHCI root HUB NEC> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen2.1: <OHCI root HUB NEC> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen3.1: <EHCI root HUB NEC> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen1.2: <product 0x006e vendor 0x0411> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON <----- Why? 3. set IP address (ifconfig) [OK] 4. ping from another host, 9 of 10 packet was lost[NG]. [OK Steps](with CardBus USB 2.0 port, about 1 times OK, 10 times tests) 1. Insert USB NIC. 2. This USB NIC was probed **USB 2.0**[OK] # usbconfig ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.1: <OHCI root HUB NEC> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen2.1: <OHCI root HUB NEC> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen3.1: <EHCI root HUB NEC> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen3.2: <product 0x006e vendor 0x0411> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON 3. set IP address (ifconfig) [OK] 4. ping and ssh [OK] [OK Steps] onboard USB 1.1 port always OK 1. Insert USB NIC. 2. This USB NIC was probed **USB 1.1**[OK] # usbconfig ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.1: <UHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen0.2: <product 0x006e vendor 0x0411> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON 3. set IP address (ifconfig) [OK] 4. ping and ssh [OK] Best Regards, --- MIHIRA, Sanpei Yoshiro Tokyo, Japan. _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
