[axe] Gigabit USB NIC, Buffalo (Melco Inc.) LUA3-U2-AGT could not be often use with CardBus USB port.

[MIHIRA Sanpei Yoshiro]

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]
