What's the difference between atausb and umass?

[Zeng Nan]

Hi,

As FreeBSD 6.2 is available now, I notice that a new feature is that ata
driver can support usb mass transport by enable atausb in the kernel. 
I'd like to know if atausb has any advantages over traditional umass.
Sometimes when I use external hard disk through usb, the system may
hang. I wonder if atausb solved this problem or not?

Regards,
