Installing the USB to Serial Adapter on Linux:
IMPORTANT: If you purchased our USB to serial adapter after October 24, 2004, your adapter uses the chipset PL-2303HX. The Linux kernel 2.6.9 and above comes with a native driver that works with this chipset. Earlier versions of the kernel do not come with a native driver for PL-2303HX.
The USB to serial adapter from Sewell Development (sold before October 25, 2004) uses the PL-2303 chipset. Redhat 8.0 and higher include a native driver for this chipset, but other distributions of Linux may also support it. Please consult your distribution’s documentation for information on usb to serial support.
- Boot Linux.
- Open a terminal window.
Enter the following lines at the command prompt. Depending on how many usb ports you have on your computer, you may only need to type the first few. The usb to serial driver can handle up to 16 separate devices.
- mknod /dev/usb/ttyUSB0 c 188 0
- mknod /dev/usb/ttyUSB1 c 188 1
- mknod /dev/usb/ttyUSB2 c 188 2
- mknod /dev/usb/ttyUSB15 c 188 15
- Attach the device to the serial connector on the adapter.
- Plug in the usb to serial adapter into a usb port on your computer.
- You should now be able to access the device via /dev/usb/ttyUSBn, where n is the usb port into which the adapter is plugged. NOTE: If you are using the usb to serial adapter with the Fastlynx Linux Slave, just type slx /dev/ttyUSBn (where n is the usb port) at the command prompt.
If you have trouble connecting to the device, first make sure the device works with a normal serial port or consult the device’s documentation and make sure it is compatible with Linux.
You may also need to try using a different port. For example, instead of ttyUSB0, try ttyUSB1.
More problems? Like all problems with Linux, try the man pages, online discussion forums, or a good manual. For information on usb to serial support for Linux, visit: http://www.linux-usb.org/USB-guide/x356.html.
