#2 Interrupt error using USB ir tower

[Pieter Smit]

Hi,

I have the USB IR Tower.
Kernel 2.6.2-rc3 with Lego module.
The kernel finds the Lego tower perfectly and loads module.

trying to execute any nqc commands cause the errors
below in syslog. The green led in the IR tower lights
up for a second

$nqc -Susb -run
