Fast Boot: USB devices impact on BIOS post times

**simplex** · 11-27-2009, 03:49 AM

Maybe you should add USB devices after 10-30 secs, for example,
give power to the USB hub 10s after computer boot.
First, try to do this manually, and if it works,
you can get some timing electrics for it.

More: I'm planning do this on-demand, for example, with an RS232 or USB relay controller,
and a program for it, integrated on the frontend/window manager. For example:
-it gives power to the touchscreen after OS fully booted
-when you start the GPS in the frontend, it gives power to the GPS device
-when you start the music player, it gives power to the USB DAC/sound card
etc, etc...
You can also control other devices with it, like mirrors, windows, etc...

FusionBrain can do all that and more, and you'll support fellow board members by buying it

Delayed power to USB hub is one way to do it. Just make sure the hub-ports is inactive/disabeled when the hub is offline. Otherwise it will try to power the devices with the power coming on the line; PC - > USB-Hub.

I've not tested this to the extent of you lot and I don't have the same board.

My board is a zotac 9300-ITX which is a completely different kettle of fish.

However I believe if you change your BIOS to 'PnP OS: Yes' (not exact wording as it changes from board to board). I think this will stop your bios issues as it won't bother addressing any PnP devices, it will leave it for the OS to deal with.

This SHOULD solve your problems, I know this and a few other select settings in my XBMC HTPC at home greatly improved boot times where it used to hang for long periods due to PnP devices.

Let us know if you have success with this.

U have all the right components, except your motherboard's bios sucks.
Believe me i've dealt with this board, and the bios is complete garbage. However, this board does support S3 hibernation, this will definitely solve all of your problem. After all these years of looking for the best boot time. I finally gave up and use s3 hibernation and i'm glad i did. There's more and more members trying this, so you should give it a try as well.

Powering a hub after windows starts is fine, but make sure it is still powered when windos resume from hibernation/STR.

Oh my god, I searched the whole net for something like this, and as always,
the most trivial solution wins: it's in the shop!!! Thank you

I don't think my MB has that option...I'll check it out though.

I wonder why would BIOS care if there was a HID or a webcam or whatever plugged. There shouldn't be any difference, as they're all usb devices! They should have a int, mem allocated, 5v and that's it.

And how Apple computers can get rid of bios altogether? How can we do that too?

Finally, is this board any good? I want a 775 or better mini ITX board and I was thinking about anything NOT-intel. Suggestions?

Zotac GF 9300, $117.00 at Amazon. [edit: it's not this one, my mistake, it's the ITX version)] Is this the one you have? How about boot times?

How can you disable or render inactive a usb port with Windows 7? Xport won't work with windows 7, not that feature at least.

I'm trying S3 right now! I think it's going to work, except for the Garmin GPS which does not work after hibernation. I'd like to disable it and then enable it after resuming...

My xport works perfectly with windows 7 RC. No idea why it wouldn't work for you. When u get xport running that problem will be solved.

Xport DOES work for me with Windows 7, but the COM port replication thing. It does not work for stopping and reestarting USB devices.

It's an issue with Garmin drivers, they're really poorly written. Lot's of posts on Garmin forums, no answers from them.

Now I've just found out, after adopting the hybrid sleep solution with the DSATX + Windows 7, that Garmin apparently DOES wake up fine after sleep, it just does not after hibernating (full off). After hibernating, just a restart will fix things.
