Query: Equus 3130 Innova code scanner

I purchased this tool on friday and recieved it on monday. I had been getting a check engine light on my 99 Accura cl and every-time I took it to Autozone it came up as an "exhaust leak" code. I had replaced the exhaust from the cat back and had not replaced the catalytic converter. When I pluged in the 3130 a "PO420 Catalyst system Efficiency below Threshold" code popped up.I changed the cat and cleared the code with the 3130 and have not had the problem again. I am very pleased with the code reader with the exception of it will not plug into a USB port on my computer, you have to purchase a seriel to USB adapter for $10.00 which is hard to find in your local Best Buy or Radio Shack. They carry a $39.99 Special Adapter which is over-kill.Thank-you Amazon.Com for providing fast shipping and Reasonable prices on Items I need!!! I have several Honda vehicles and tried this code reader on all of them including a 2007 Civic Si and it works on them all.
