 Posted: Sun Oct 24, 2004 1:34 am Post subject: USB 2.0 High-Speed with nForce3 250GB: How? |
 |
|
I have an Epox 8KDA3 (AMD64 nForce3-260GB) board which most definately supports high-speed USB 2.0. However, when I compile both OHCI and EHCI support into the kernel*, I can no longer get any USB storage devices to work - the kernel doesn't assign a /dev device to them, so I can't mount anything. When I compile just OHCI, it all works, but I have to run everything at full speed (12 Mb/s) instead of high speed (450? Mb/s).
* I've never been able to get this to work. I originally thought it was a bug in 2.6.8, but it's still there in 2.6.9...
This is the relevant dmesg output (immediately after inserting a USB thumb drive), first for OHCI only:
| Code: | ohci_hcd 0000:00:02.1: wakeup
usb 2-3: new full speed USB device using address 2

And for both OCHI and EHCI:
| Code: | usb 1-6: new high speed USB device using address 2

Anyone know what's going on?

| I've now tried UHCI as well. Has anyone gotten high-speed USB to work with an nForce3 board? |

With OHCI+EHCI, my low-speed USB devices work fine: keyboard and mouse. However, the system tries to use EHCI with my USB key and my external IDE HD enclosure, and it doesn't assign a /dev node to either device (see my first post above).
dmesg from just OHCI:

With just OHCI, everything works fine. The storage devices are assigned /dev nodes, but everything runs at low- or full-speed - no faster than 12 Mb/s (I think that's the full-speed standard, anyway), even though the key and the HD enclosure support high-speed USB (450 Mb/s, I think).
just EHCI:

With just EHCI, nothing works. The keyboard and mouse aren't recognized, and the key and the HD don't get /dev nodes (but are detected).
OHCI+UHCI:

OHCI+UHCI is just like OHCI alone. Since my motherboard doesn't support UHCI, it seems like the drivers aren't activated. |

Just for laughs I tried OHCI+EHCI and EHCI only with no other USB devices attached. Since Linux doesn't see my keyboard when it's attached to the PS2 port, I had to SSH in to do the tests.
Regardless, high-speed still doesn't work. The same dmesg output appears as in my first post, and the USB key doesn't get a /dev node. |
