lsusb applet not found

Hi,

When I run the 'lsusb' command, it tells me 'lsusb: applet not found' message. How do I solve this ?

When I plugin a USB flash drive into the system, I get a weird message. It must be plugged in for the first time into the USB port and after that subsequent USB drives will not spawn the message again.

[ 14.935514] Clocksource tsc unstable (delta = 200916449 ns) [ 14.826599] Switching to clocksource l4kipclk

I am missing something in the L4Linux/Fiasco.OC build image I made to enable USB support ?

Are the clocksource and lsusb messages correlated ?
