guys, what usb OBD should I buy for my windows 7 carputer in a 2011 prius...(cheap one) I dont want the com, bluetooth or wirless one. just the plain USB type that will work and comes with the software.
Go to eBay and search for V1.4 ELM327 OBD2 OBDII CAN-BUS Diagnostic Scanner USB. I bought one from ebay seller tomtop_digital for about $14 and it shipped free from China. Got it in about two weeks. The guy has sold way over 1,000 of them. You can also get the Elmscan 5 Compact from Amazon (which I don't have, but it is a little more expensive, and others here have reported it works).
