USB 3.0 support

[geronimo1958]

Late last year I remember reading in these forums that USB 3.0 support was planned.

A few days ago I implemented the suggestion in the follwoing thead:

http://forums.freenas.org/showthread.php?6833-ASMedia-ASM1042-USB-3-0&highlight=usb+3

I added the tunable variable:

xhci_load set to YES.

I reenabled USB 3.0 support in my BIOS and rebooted.

It did not work.

Any ideas????

Planned doesn't mean it automagically happens in a year. USB 3.0 support isn't available until FreeNAS upgrades to FreeBSD 9.0 much later this year, *maybe* Christmas.

OK. Thanks for the update.

I hope a month and a half doesn't deem this a zombie already.

Could you elaborate on the state of USB 3? The known issues page mentions how support is disabled by default because it panics some motherboards, but provides information on adding the tunable to enable it. But, if support won't arrive until FreeNAS is based on FreeBSD 9, what does the xhci_load tunable do? Would USB 3 ports simply not function at all without that enabled?

I enable xhci_load and was able to have a working usb3 on my p8h77-i
Enabled in my bios and with the following settings:
- legacy usb3.0 support enabled
- ehci hand-off disabled.

I know my USB3 ports on one of my servers worked as USB2.0 without enabling USB3. Big picture, USB3 doesn't bring much to the table except for when you are plugging in drives to copy data to/from the server. Hopefully it's not permanent since most people that do result in data loss untimately.

Bootup times from a fast USB3 drive is only marginally better than using the same drive in USB2.

That's good to hear. That's the board I'm using so I'll have to check the BIOS settings. Thanks.

I'm not sure what you mean here. Most people using USB3 or copying data to/from external drives ultimately lose data?

Ah, gotcha. Yeah, I'm looking at it for keeping offline backups up to date.
