The USB cable is used for connection and communication between the computer and external devices, as well as for charging the phone and connecting it to the outside. In layman's terms, it is used to transfer data and charge. So what are the main categories of USB data lines:
1, ordinary USB data cable
This does not have a central control chip, you must plug in the mobile phone computer to recognize the line, the price is cheap. Typical models: Samsung CDMA series, D500 series; Motorola E398 series, V3 series; Nokia DKU-2; NEC N720 series; Siemens 65 series and so on.
2, with IC USB data cable
With a central control chip, the model number of the ordinary chip is 2303, 2101, 3116, and the line will be recognized without plugging in the mobile phone computer. Since the price of an IC is more than 10 yuan, the price is more expensive than without the IC. The working principle of the data line with chip is USB to COM, which converts the USB interface into a serial port and displays it on the computer. Typical models: Samsung E638 series, D418 series; NEC N610 series; Siemens 25 series, 55 series; Sony Ericsson mobile phone data cable; Panasonic mobile phone data cable; Lenovo mobile phone data cable and so on.
3, special USB data cable
This is a non-ordinary popular chip, special special models such as: DKU-5, CA-42, DCU-11 and so on. Note: Do not mistakenly believe that the quality of the IC is good, the quality of the IC is not good, and the actual without the IC is based on the applicable model of the mobile phone.
