Re: how I know if a interrupt is ioapic_edge_type or ioapic_level_type? [Was Re: [Fwd: Re: [Linux-usb-users] Fwd: Re: 2.6.17-rc6-mm2 - USB issues]]

Chris,

If you keep me posted on the patch when released (I'm not on the kernel 
list, too high volume for me) I'll be happy to give your patch a whirl 
on my test box against whichever kernel you patch.

Your last point is real good, how DOES Windows figure it out? In saying 
that, without the VIA drivers I only have USB1.1 support on this 
motherboard... Again, happy to test some theories if you have some tests 
you'd like ran...

Cheers,

:)Johny
