USB on Kernel 2.6.10

My brand new DERI-Korea pendrive finally works on my slack running kernel 2.6.10. It was so frustrating to have a 512 MB pendrive and not being able to use it, so, after a lot of googling, I found something I can call a ``solution'': boot the 2.6.10 kernel appending ``pci=noacpi'' string or edit lilo.conf adding the line

append="pci=noacpi"

in the section relative to kernel 2.6.10 and then issue a `lilo -v`.
It worked for me and for my pendrive, now I can't try with my other usb devices (an mp3-player pendrive and a camera), I hope it won't give more troubles.
