Since Dapper pre-releases USB-related problem with booting

Bug Description

Binary package hint: initramfs-tools

I was running breezy without any problem, just perfect.

- Trying to load dapper flight7 from a live-CD, it stops and freezes defnetly on "mounting root file system".

- Upgrading from breezy to dapper via upgrade-manager, it works perfectly till rebooting system where it stops and freezes defnetly on "mounting root file system".

- booting from live-CD but removing "quiet and splash" from F6 command-line: it works and starts live-CD. Dapper works, installed in RAM, but installing on hd, it starts till creating partitions: ERROR, not able to create partitions!
So dapperflight7 is not able to "mount root file system" and not able to create the necessary partitions hda1 (/) and hda5 (swap), even they are present on the hd from previous breezy installation!

- I found that disconnecting the memorycard reader Icybox during boot session makes ubuntu start well, without problem. Hotplugging it afterwords, it works well.

So that means, with my poor experience, that there should be no problem with kernel but rather in booting session, booting script...? Something changed since breezy?
The problem occurs only during boot session and probably is related with USB

The problem still exists booting with ubuntu 6.10: freeze on "mounting root file system"
System runs well with Windows XP.
Motherboard is ASUS 8N32-SLI DELUXE

A seemingly random comment was posted (by "vijay") on a bug report that (I believe) is not at all related, but the comment may provide valuable information: https://launchpad.net/ubuntu/+source/initramfs-tools/+bug/30333/comments/32
Hopefully vijay can chime in and help us out...

I was testing Vijay's solution: switsching motherboard USB from High speed to Full speed and it works now without problem.
Comment from Asus: EHCI hand-off support is missing.

What's EHCI? Is it finally a bug or not?
Thanks for your precious help.

I am referring to a comment you posted on bug 30333 ( https://launchpad.net/ubuntu/+source/initramfs-tools/+bug/30333/comments/32 ).

I believe I reported bug 30333. Are you sure you aren't thinking of another bug report? Furthermore, I'm pretty sure my problem was not related to USB.

Right - I created this report so we can collaborate here and get down to the heart of the issue. :)

Marc, could you please chime in here.
