Usb2 and hal issue

Hi all,
I don't know how provide further details, but on my system there is
something of wrong between new usb2 drivers and hald.
Top shows hald's cpu load at 100% while with old drivers it's 2-4%.
I tried rebuilding hald, loading/unloading each usb2_* device but
nothing changed, so I suspect the problem is located in usb2_core.
