Public bug reported:
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.
