If the output of
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
should be "powersave", then run
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
for testing purpose.
They are set to performance with the indicator-cpufreq
Don't troubleshoot by running too many command,
start with simply
testing by using different USB ports.
BIOS settings might be important, too, but IMO you first should follow
my hints, before digging deeper.
