Using haiku's USB with R5

Has usb in haiku advanced enough to call for some newer prebuilt binaries for R5? Is this something that should be on bebits.com? I would love to see full usb support in R5. Refer to this blog http://haiku-os.org/blog/mmlr/2007-04-20/using_the_haiku_usb_stack#comment-8328
