Bug Description

Resolution of LP: #1645591 added support for Exar USB UART devices in Ubuntu Xenial kernel. However, the devices fail to RX data after system resumes from suspend-to-ram(S3) and suspend-to-disk(S4). This bug is to track the integration of the driver released by the vendor to fix this issue.

Changelog:

Version 1B, 11/6/2015
Fixed Bug: The conditional logic to support kernel 3.9 was incorrect(line 396 in xr_usb_serial_common.c).

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

Exar serial devices are typically enuremated as /dev/ttyXRUSB[0-3]

This bug is used for tracking purposes, please do not triage.
