# - control: any device can do this
# - out, in:  out needs 'bulk sink' firmware, in needs 'bulk src'
# - iso-out, iso-in:  out needs 'iso sink' firmware, in needs 'iso src'
# - halt: needs bulk sink+src, tests halt set/clear from host
# - unlink: needs bulk sink and/or src, test HCD unlink processing
# - loop: needs firmware that will buffer N transfers
#
# run it for hours, days, weeks.

d86e64768859, an error in the edit results in the wrong firmware
being loaded for some models of the RTL8188/8192CE. In this condition,
the connection suffered from high ping latency, slow transfer rates,
 and required higher signal strengths to work at all

https://bugzilla.opensuse.org/show_bug.cgi?id=1017471, and
https://github.com/lwfinger/rtlwifi_new/issues/203 for descriptions
of the problems. This patch fixes all of those problems.
