The most common interface cables are:

HEX-V2: This is a wired interface that works with USB only. It supports all vehicles based on VW's MQB platform, as well as most older vehicles that use K-line or CAN protocols.
HEX+CAN: This is an older wired interface that works with USB only. It supports most vehicles that use K-line or CAN protocols, but not the ones based on VW's MQB platform.
KII-USB: This is an older wired interface that works with USB only. It supports most vehicles that use K-line protocol only, but not the ones that use CAN protocol or are based on VW's MQB platform.
You can buy these interface cables from Ross-Tech or from authorized distributors. You can also find some clone or counterfeit cables online, but they may not work properly or damage your car or PC.
