Rusty Russell 57673c2b0b Use 'E' instead of 'X' for unsigned module taint flag.
Takashi Iwai <tiwai@suse.de> says:

Note: this code should be cleaned up, so we don't have such maps in
three places!

Description: Maximum time allowed for periodic transfers per microframe (μs)
[ USB 2.0 sets maximum allowed time for periodic transfers per
microframe to be 80%, that is 100 microseconds out of 125
microseconds (full microframe).
However there are cases, when 80% max isochronous bandwidth is
too limiting. For example two video streams could require 110
microseconds of isochronous bandwidth per microframe to work
together. ]
Through this setting it is possible to raise the limit so that
the host controller would allow allocating more than 100
microseconds of periodic bandwidth per microframe.
Beware, non-standard modes are usually not thoroughly tested by
hardware designers, and the hardware can malfunction when this
setting differ from default 100.
