RELEASE NOTES
=============
Silicon Labs Virtual COM Port (VCP) Universal Driver for Windows 10
Package version: 10.1.8
Release date: 2019-06-24
This package contains a Virtual COM Port Universal driver for Microsoft
Windows 10 for use with Silicon Labs VCP USB Serial Bridges. These devices
include the CP2102N, CP2102, CP2103, CP2104, CP2105, CP2108, CP2109.
OS VERSIONS
-----------
This package provides the CP210x VCP driver for the following versions
of Windows:
- Windows 10 (x64, x86)
CHOOSING VCP DRIVER VERSION
---------------------------
VCP drivers of version 10.0.0 and later are released for Windows 10 as
Universal Drivers. This means they do not work on older version of Windows
such as Window 7 and 8.1. You should use this driver if you only need
support for Windows 10, or you need the Universal driver. If you require
support on older versions of Windows, you should use the legacy VCP driver
which can be found on the Silicon Labs web site. The legacy Windows VCP
drivers have version numbers less than 10.0.0.
CONTENTS
--------
The VCP driver package contains the following files and directories:
- silabser.inf -- Driver information file
- CP210xVCPInstaller_x64.exe -- 64-bit installer
- CP210xVCPInstaller_x86.exe -- 32-bit installer
- SLAB_License_Agreement_VCP_Windows.txt -- Software License
- CP210x_Universal_Windows_Driver_ReleaseNotes.txt -- this file
Additional files needed by installer

alternate PID values of 0xEA63, 0xEA7A, and 0xEA7B. These are not default
values.
Otherwise, unzip the .zip file and you will have a directory containing the
driver installer files.

RELEASE NOTES FOR 10.1.8 (2019-06-24)
Changes for VCP Driver
==============================================================================
MCUSW-412 | Certified for Windows 10 RS6.
MCUSW-484 | WDFVERIFY() added to the driver. Configurable via Registry.
MCUSW-495 | Clear RTS on CloseHandle().
MCUSW-508 | IOCTL_SERIAL_GET_COMMSTATUS refactored to reduce USB-bus
| bandwidth, while still offering timely reporting.
MCUSW-518 | WDFVerifier parameter ForceLogsInMiniDump Registry parameter
| added for improved supportability.
MCUSW-519 | Resolve an SDV-identified issue: do not double-complete a
| Request on error paths.
MCUSW-526 | Creates the framework USB device object with client contract
| version USBD_CLIENT_CONTRACT_VERSION_602/0x602 (I.e. Register
| with "new" (to Windows 8) Windows USB driver stack).
******************************************************************************
RELEASE NOTES FOR 10.1.7 (2019-03-26 (DriverVer = 03/26/2019,10.1.7.2399))
Changes for VCP Driver
==============================================================================
MCUSW-473 | Fix length of nul-terminated legacy Dos Name string written to
| HARDWARE\DEVICEMAP\SERIALCOMM Registry key.
MCUSW-483 | Fixed bug for Max Baud rate for CP2101, CP2104, CP2105 and
| CP2108 devices.
******************************************************************************
RELEASE NOTES FOR 10.1.6 (2019-03-19 (DriverVer = 03/15/2019,10.1.6.2388))
Changes for VCP Driver
==============================================================================
MCUSW-445 | Fix a blue-screen system crash bug with handling of ioctl
| IOCTL_SERIAL_WAIT_ON_MASK during power state changes.
******************************************************************************
RELEASE NOTES FOR 10.1.5 (2019-02-19 (DriverVer = 02/19/2019,10.1.5.2368))
Changes for VCP Driver
==============================================================================
MCUSW-414 | Implement an undocumented Registry-configured feature to ignore
| IOCTL_SERIAL_PURGE.
MCUSW-417 | Read many of the Registry "parameter"-type settings first from
| the "parameters key" and then from the "hardware key", with the
| "hardware key" taking precedence (allows "driver wide, all
| devices" setting, but provides the capability to specify per-
| device settings (before we only supported per-device
| settings)).
|
MCUSW-439 | Fixed a bug whereby Close()-Open() on a CP2102N could get USB
| data toggle confused (I.e. issue USB CLEAR_FEATURE(HALT) to
| bulk endpoints to reset data toggle back to DATA0).
MCUSW-449 | Fix a Max Baud Rate bug (use device-specific MaxBauds (from the
| data-sheets): 3 Mbaud for CP2102N, 1 Mbaud for all other CP210x
| devices.).
MCUSW-450 | Fix Verification BSOD (race condition in the VCP device driver
| that can cause double completions): Only call
| DetachForCompletionUNcancelable on success of UNmark as
| cancelable in handling of IOCTL_SERIAL_WAIT_ON_MASK-related
| requests.
******************************************************************************
RELEASE NOTES FOR 10.1.4 (2018-12-07 (DriverVer = 11/26/2018,10.1.4.2290))
Changes for VCP Driver
==============================================================================
MCUSW-134 | Fixed an issue with handling of IOCTL_SERIAL_SET_WAIT_MASK,
| IOCTL_SERIAL_WAIT_ON_MASK, with the SERIAL_EV_RXCHAR event and
| data arriving from the device into the driver. Previously, an
| indication of arriving data was made before making the data
| available, causing, in some conditions, subsequent requests for
| data after notification of data available to not deliver any
| data.
MCUSW-144 | Onecore-based editions of Windows 10 (I.e. Windows 10 IoT Core)
| do not, by design, create PortName entries in the Registry to
| specify the device's legacy DOS name (I.e. COM<n).
