Can't boot gentoo due to USB V2.0 vs V1.1 problem [SOLVED]

Hi,

I'm installing gentoo 2005.1 AMD64. When I first entered my universal bootcd, the gentoo install kernel wouldn't start, gentoo -fb told me it wouldn't pass USB blablasomething. I didnt worry about it, because I just choose "gentoo nousb".
Installation went pretty well. Got GRUB(dual-boot) up and running and all seems to go well.

But when booting Gentoo using the GRUB screen, I again run into the USB problem. This are the last lines before it hangs:

ehci_hcd 0000:00:02.2 EHCI HOST Controller
ehci_hcd 0000:00:02.2 debug port 1
ehci_hcd 0000:00:02.2 new USB registered assigned bus number 1
ehci_hcd 0000:00:02.2 irq 185, io mem 0xdf00400

Do I have to recompile the kernel again?(don't really feel like it) Or is there an easier sollution? I'm not planning to use any USB devices yet om my Gentoo machine. Can I disable/hide the USB ports anywhere, so Gentoo won't wine about it?\

Thanks,
David (Holland)

Yes, it is a problem with the USB. When I go into my bios and switch Onchip USB from V1.1+V2.0 to just V1.1, the gentoo boot still gives alot of errors when it talks about USB stuff, but it goes on (just to another unrelated error unfortuatnally) But now I know it has got something to do with USB 2.0 vs USB 1.1

I've got two questions
1) how to resolve the USB 2.0 problem (I have to, because when I switched to windows with V1.1 only my mouse didn't work)
2) why DID my USB mouse work during the gentoo install when my USB was set to V2.0.

I find this matter rather confusing, the kernel refuses to boot due to USB 2.0, but during install session my mouse works perfectly...

Goot with the live CD da a

Code: Select all

lspci 
lsmod

this will give you an idea of what the livecd is doing and how. Then do the same to your kernel

Ok, so I booted my live cd (gentoo nousb)
Mounted the neccesary stuff.

lspci tells me:

nforce3 EHCI ISB2.0 controller (rev a2)

(and some other USB stuff which I think isn't the issue, although it might explain why my USB mouse does work...)

lsmod tells me:

uhci_hcd used by 0
ehci_hcd used by 0
ohci_hcd used by 0
usbcore used by 5 (uhci_hcd,usbhid,ehci_hcd,ohci_hcd)

Ok, now, I am the mother of all noobs, do you mean I have to do this?:

Code: Select all

chroot /mnt/gentoo/ /bin/bash
env-update
source /etc/profile

If this means "I am doing the same for the kernel" the the results of lsmod are the same as in the live cd environment. Furthermore I would like to add my usb mouse worked in both environments. So I'm also wondering what booting the live cd with "gentoo nousb" is all about.

So what do I have to do to let my kernel boot beyond the errors I have stated before?

Yes you have to chroot or boot if you can and then include the same usb support in your kernel . YOu also have to install coldplug and hotplug and add them to run level boot and default, respectively.

Now I have used genkernel to configure my kernel to be just like the live cd kernel. I have installed hotplug and coldplug and made then to run boot level. I ajusted my grub to deal with the genkernel config. when I now boot, I still get the same USB error. I'm sick of it. I just want to get the show on the road. I don't need USB on my linux. Can anyone tell how to go past the error in my boot?

Ok, correct me if I'm wrong,

configuring the kernel using genkernel results in a kernel environment just like the livecd environment right? And for me to enter the live cd environment I HAVE to boot using the command:

Code: Select all

gentoo nousb

Or else it will not boot due to USB-blablabla.
So, now I have the same kernel config as the livecd. And just like the livecd, my kernel will not start due to USB-blablabla.

So, is there some kind of command I can implement in my grub.conf which works just like the "nousb"option while booting my live cd?

I really would appreciate an awnser so I can go on with my install.

Thanks.

That "nousb" command also seems to works if you put it in grub.conf
