Q: How to install USB 1.1 TO RS232 Cable Linux driver and compile? A: 1. Under root folder, create a new folder and copy USB 1.1 TO RS232 Cable source code to new folder. 2. Open "Makefile" with GEDIT or KATE under new folder. 3. Modify line 5 "KINCLUDES=/usr/src/linux/include". Example: "KINCLUDES=/usr/src/linux-2.4.7-10/include". You could find folder name on Linux. 4. Open terminal mode and login root user. 5. Go to the new folder and then type "make all" to compile the PL-2303 source code. This will create two files: "pl2303.o" and "usbserial.o". 6. Type "make inst" that will install the PL-2303 Linux driver into Linux. 7. Plug the PL-2303 cable into USB port and key-in "dmesg", it will show "Prolific USB Serial Adapter converter now attached to ttyUSB0 (orusb/tts/0 for devfs)". This means the cable is now working under Linux. Note: You must login into root user in order to successfully compile and install.
