Subject: Problem with USB 1.1 Storage plugged in USB 2.0

Hi kernel folks,

I just enter this bug because I want to buy a new laptop and very often
there's only USB 2.0 port on new ones...

Quickly my problem :
I try to mount as a usb-storage my Minolta DiMAGE F200 (which seems to
be USB
1.1) on a kernel 2.6

If I plug it on a USB 2.0 plug, it hangs
If I plug it on a USB 1.1 plug, it works

With kernel 2.4 (module usb-uhci) it works whatever the plug I use.

I've posted more information there :
http://bugme.osdl.org/show_bug.cgi?id=3711

If there's a patch around or something that I can test, ask.

Thanks for your job.

PS : Please cc me as I'm not on the list

Reproductable, I have an Adaptor for SecureDigital Cards to download images
from a cammera, And only works in USB 1.1 plug, Kernel is 2.6.6 and 2.6.7.
Cause I not own the adaptor, I don't have a chance to try without ehci enabled
(rmmod ehci-hcd).
