I need some advice how to best tackle this problem I'm having with an = ADMtek USB To LAN Converter in conjunction with an nVidia nForce MCP79 = USB chip: --- config begin --- root@creutzfeld:(~)# uname -a FreeBSD creutzfeld.z.net 8.2-STABLE FreeBSD 8.2-STABLE #7 r226546: Wed = Oct 19 22:08:28 CEST 2011 = root@creutzfeld:/usr/obj/usr/src/sys/CREUTZFELD amd64 root@creutzfeld:(~)# usbconfig list ugen0.1: at usbus0, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE ugen1.1: at usbus1, cfg=3D0 md=3DHOST spd=3DHIGH = (480Mbps) pwr=3DSAVE ugen2.1: at usbus2, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE ugen3.1: at usbus3, cfg=3D0 md=3DHOST spd=3DHIGH = (480Mbps) pwr=3DSAVE ugen3.2: at usbus3, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DON ehci1: mem = 0xfae7e800-0xfae7e8ff irq 21 at device 6.1 on pci0 --- config end --- This ADMtek device gets roughly 10MBit downstream with the configuration = above. When used with the same OS on a board with an Intel 82801GB/R = (ICH7) USB 2.0 controller it gets 64MBit downstream, which is the = maximum I can get from my ISP. I don't see anything unusual in the system messages, thus I suspect it's = an issue with the USB implementation for the nForce chipset. What can I do in order to find out what's the bottleneck here? Thanks in advance, Marcus
