Installation of USB-to-serial driver in laptop + win7

For the convenience of travel, changing equipment, changing a notebook, tangle for a long time ......

The tangle of using a notebook for underlying development is not something we can understand. After all, we are in the second class. The laptop is okay. Maybe you still use XP. It's good. Laptop + win7 is a little headache, USB to serial port driver, looked for a long time, really pull, but still get it done.

I searched for a channel on the Internet, but I changed to a dozen drivers, which were not identified. I was depressed for a long time, not general. Although many people installed it easily, different laptop manufacturers and different win7 systems (some family, some flagship, some genuine, some pirated, some simplified, and some unstable ), from this point of pain. Looking for him in the crowd, he did not find any other websites in China or abroad.

However, a miracle always happens by accident. If you accidentally find a usable one, it may be luck.

Generally, the USB-to-serial port chip uses pl2303, and the driver of pl2303 is unavailable. On the other hand, the hl2303 driver is installed. It turns out that the donkey lips can be reached, in fact, the miracle is not accidental.

Next, we will describe the specific solution steps:

First of all, download the installation package: USB-232.zip

1. Install pl2303_prolific.exe In the downloaded folder first. This is the official driver of original pl2303, without a doubt. After installation, right-click my computer --- manage ---- device management ----- other devices ---- there is a USB-serial similar device, either with an exclamation point, it is either a question mark. If there is no, but "prolific USB-to-serial COMM port" is added to "port (COM and LPT)" (if there is an exclamation point, you have to continue ), the icon is normal and has no other symbols. Congratulations, you are lucky to use it directly theoretically. (PS: This driver is an all in one package installer found on a foreign website. The installation is more likely than other versions .)

2. If it is described above, it is unavailable. Then, continue. Right-click the USB-to-serial words of the device, choose Update driver ----- browse computer to find the driver software ----- select extracted directory USB-232, directly select this home directory, let it traverse the subdirectories and find them. The installation is successful without an accident. The default enabled port may be com3 or another port. You can set it in advanced settings of the device Properties Based on the port usage on your computer.

Just so. Hope it's helpful to you.
