How to enable support for the Perle Ultraport USB for Linux kernel 2.4.20 and higher kernels (including 2.6.x)

Solution:

For Linux kernel 2.4.20 to 2.4.22:

Copy the new UltraPort USB files ftdi_sio.c and ftdt_sio.h from the CDROM into the kernel (source directory)/drivers/usb/serial.

For example, cp /mnt/cdrom/drivers/ultraport USB/linux/1.3.4/ftdi_sio.c /usr/src/linux 2.4.x/drivers/usb/serial.

Go to step one below (Linux 2.4.23 or higher section)

If you have a Linux 2.4.23 or higher kernel:

1. Enable support for the FTDI USB driver in your kernel.
• change directory to your Linux sources
• run "make menuconfig" or "make xconfig" to enter the kernel configuration
• navigate to USB Support -> USB Serial Converter Support
• enable Modular support for USB FTDI Single Port Serial Driver
2. To build and install the module run: run "make modules" and then "make modules_install"

If you have a Linux 2.6.x kernel then:

1. Enable support for the FTDI USB driver in your kernel.
2. change directory to your Linux sources
• run "make menuconfig" or "make xconfig" to enter the kernel configuration
• navigate to Device Drivers -> USB Support -> USB Serial Converter Support
• enable Modular support for USB FTDI Single Port Serial Driver
3. To build and install the module run: run "make" and then "make modules_install"

The module will be called "ftdi_sio"
