I am having almost the same issues.  I want to share my story because some • of
the key elements in your story match mine exactly:

Computer: Toshiba Satellite/WinXP/3-USB 2.0
RCX 1.0
USB tower
Software: RIS 2.0, SDK 2.5, Bricxcc (all have same results)
Problem:  Computer locks up when accessing the USB IR tower.  Light on • tower

USB tower checks out fine.

Possible solution:  It may be possible that the Toshiba people didn't put • enough

(if the PCMCIA card does not work).  Another possible solution I will try • is
hacking the USB tower to accept alternate power sources (like the old • serial
tower did).
