USB Tap Issue with CW 8.8

I'm trying to set up CodeWarrior (CW Dev Studio, Power Architecture v8.8) to use USBTap (looks like REV A) with a board using MCP885VR133 chip and a WinXP host.

The problem I'm having is getting CW to see the USBTap device. The TAP is connected via USB2.0 and it shows up fine in "Device Manager"/"System devices"/"CodeWarrior USB TAP". The TX/RX LED on the TAP is blinking GREEN, RUN/PAUSE LED is off.

When I try to go to "Debug"/"Attach to Process" in CW, I get an error "JTAG Clock Speed Change Error: Please check your JTAG clock speed." This same message comes up even if I DON'T have the TAP connected to the PC. I tried going to CCS (CodeWarrior Connection Server version {4.13}) and running "show cc", I get "0: USB open failure", and when I try "updateutap" I also get "USB open failure". Once again, these errors are the same whether or not I have the TAP connected. What else can I try?
