I was talking in context of usb/ip's show_status. It writes a lot of data
into this buffer. Which seems to over flow the buffer. But anyways, I
will check if it can be reduced or at least be splitted into differnt
device attributes.

BTW, Greg, Did you take a look at other patches I had sent? Are are worth or
I need rework?
