Exar USB Serial Driver ====================== Version 1A, 1/9/2015 This driver will work with any USB UART function in these Exar devices: XR21V1410/1412/1414 XR21B1411 XR21B1420/1422/1424 XR22801/802/804 The source code has been tested on Linux kernels 2.6.18 to 3.4.x. This may also work with other kernels. Installation ------------ * Compile and install the common usb serial driver module # make # insmod ./xr_usb_serial_common.ko * Plug the device into the USB host. You should see up to four devices created, typically /dev/ttyUSB[0-3]. Tips for Debugging ------------------ * Check that the USB UART is detected by the system # lsusb * Check that the CDC-ACM driver was not installed for the Exar USB UART # ls /dev/tty* To remove the CDC-ACM driver and install the driver: # rmmod cdc-acm # modprobe -r usbserial # modprobe usbserial # insmod ./xr_usb_serial_common.ko Technical Support ----------------- Send any technical questions/issues to uarttechsupport@exar.com.
