Description Fridtjof Busse 2012-06-26 20:30:11 UTC
Running FreeBSD 9.0 on an HP Microserver N40L, my external backup discs are only detected as full speed instead of high speed:
$ sudo usbconfig

Writing to the disc is only possible at <1 MB/s. The same happens with a different USB disc (tried both a USB2 and a USB3 disc with different enclosures).
The only way I could get more USB speed so far was with a USB3 PCIe card, but unfortunatly I get a kernel panic after some time during rsync transfer (I'll file a different SR for this, seems to not only happen to me [1]).
Worked fine in a linux live-CD, so it is not a hardware-problem.
If you need any additional logs, please let me know.

Hi,

Please check with pciconf -lv that all EHCI PCI devices have a driver 
attached.

Also check that:

sysctl hw.usb.ehci.no_hs

Is not set.

Have you tried all ports?

Hi,

Your EHCI hardware is quirked and has known issues:

sys/dev/usb/controller/ehci_pci.c

        switch (pci_get_vendor(self)) {
        case PCI_EHCI_VENDORID_ATI:
                /* SB600 and SB700 EHCI quirk */
                switch (pci_get_device(self)) {
                case 0x4386:
                        ehci_pci_ati_quirk(self, 0);
                        break;
                case 0x4396:
                        ehci_pci_ati_quirk(self, 1);
                        break;
                default:
                        break;
                }
                break;

Do you see a QUIRK printout in dmesg?

Maybe you can also need to try setting quirks in /boot/loader.conf:

hw.usb.ehci.lostintrbug: 0
hw.usb.ehci.iaadbug: 0

--HPS

Only this line:
umass0:  SCSI over Bulk-Only; quirks =3D 0x0100

> Maybe you can also need to try setting quirks in /boot/loader.conf:
>=20

>=20

I set the configuration in /boot/loader.conf, but no change after =
reboot. Still less than 1MB/s write speed.
