ehci cause my umass0 to hang at boot, no ehci kills my mouse...

[Nicolas Blais]

I have a Mitsumi 7/1 multi-card reader with integrated floppy which works 
great in XP. In FreeBSD 6-CURRENT, the floppy part works fine (it's a 
seperate cable) but the memory card part causes a 5 minute delay at boot 
(during probe) and ends up not working at all. With ehci enabled in my kernel, 
I get this at boot:

Here's the  snipped dmesg -v (with ehci enabled in kernel):

At that probe part, there is about a minute between each tries which is quite 
long downtime.

When I remove ehci from my kernel, boot is very fast, no longer hangs at probe 
and umass0 is still detected:

And yet no 5 minute delay during the probe.

Unfortunatly, my mouse is not detected at boot and doesn't work unless I 
unplug it and replug it, then it will work (bug in uhci?). 

Also, although my cardreader is still detected, I can't seem to make /dev/da0 
whether I :
camcontrol rescan 0
camcontrol rescan 0:0:1 (to 4)
and camcontrol devlist shows my dvdr:
<HL-DT-ST DVDRAM GSA-4163B A104>   at scbus2 target 0 lun 0 (pass0,cd0)

Please help,

Nicolas.
