Subject: Re: high load with usb device
Date: Tue, 14 Sep 2010 09:51:27 -0600	[thread overview]
Message-ID: <4C8F99FF.8060808@cisco.com> (raw)

What's your clock source on the host?
cat /sys/devices/system/clocksource/clocksource0/current_clocksource

With the usbtablet device the host clock source is read 2-3 times for
frequently which for acpi_pm and hpet jack up the CPU.
