Hi everybody I've finally got my FreeBSD 6.2-release working, and even compiled my own kernel and everything, so that's good. However when I connect my USB pen drive and/or USB-IDE external harddrive, I can only transfer at about 1 MB/s as if they were USB 1.1 devices (and they're 2.0). This is even more puzzling to me, since when I plug them in my dmesg says: da0 at umass-sim0 bus 0 target 0 lun 0 da0: <Maxtor 6 Y080L0 0811> Fixed Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 78167MB (160086528 512 byte sectors: 255H 63S/T 9964C) da1 at umass-sim1 bus 1 target 0 lun 0 da1: < USB Flash Memory 6.00> Removable Direct Access SCSI-2 device da1: 40.000MB/s transfers da1: 489MB (1001472 512 byte sectors: 64H 32S/T 489C) I also looked at the output from "usbdevs -v": Controller /dev/usb0: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), nVidia(0x0000), rev 1.00 port 1 powered port 2 powered port 3 addr 2: low speed, power 98 mA, config 1, USB-PS/2 Optical Mouse(0xc025), B16_b_02(0x046d), rev 98.02 port 4 addr 3: full speed, power 50 mA, config 1, Hub in Apple Extended USB Keyboard(0x1003), Mitsumi Electric(0x05ac), rev 4.10 port 1 powered port 2 powered port 3 addr 4: full speed, power 50 mA, config 1, Apple Extended USB Keyboard(0x020c), Mitsumi Electric(0x05ac), rev 4.10 port 5 powered port 6 powered port 7 powered port 8 powered port 9 powered port 10 powered Controller /dev/usb1: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), nVidia(0x0000), rev 1.00 port 1 powered port 2 powered port 3 powered port 4 powered port 5 powered port 6 addr 2: high speed, self powered, config 1, USB TO IDE(0x0702), vendor 0x05e3(0x05e3), rev 0.33 port 7 powered port 8 addr 3: high speed, power 100 mA, config 1, USB Flash Memory(0x6533), vendor 0x0930(0x0930), rev 1.00 port 9 powered port 10 powered So the system seems to recognize the devices correctly, but still only transfers at low speed. I have no problems on other peoples winxp's or with ubuntu (which unfortunately doesn't recognize my new motherboard's ACPI-something and crashes at will). Mighty experts, please help! -esben
