OS VERSIONS ----------- This package provides the CP210x VCP driver for the following versions of Windows: - Windows 10 (x86 32/64 bit) - Windows 8.1 (x86 32/64 bit) - Windows 8 (x86 32/64 bit) - Windows 7 (x86 32/64 bit) CONTENTS -------- The VCP driver package contains the following files and directories: - slabvcp.inf -- Driver information file - CP210xVCPInstaller_x64.exe -- 64-bit installer - CP210xVCPInstaller_x86.exe -- 32-bit installer - SLAB_License_Agreement_VCP_Windows.txt -- Software License Additional files needed by installer - dpinst.xml - slabvcp.cat - x64/ - x86/ INSTALLING ---------- Unzip the .zip file and you will have a directory containing the driver installer files. ### Prompted install ### If Windows prompts you to install a driver for a CP210x device (for example, if you plug a CP210x into your computer): 1. Use the dialog to browse for the driver location 2. Locate the driver folder (that you previously unzipped) 3. Follow the instructions ### Manual install ### 1. Using Windows File Explorer, locate the driver folder (that you previously unzipped) 2. Determine if you have 32-bit or 64-bit Windows 3. Double click to run the .exe file named CP210xVCPInstaller_xnn.exe (where xnn is x64 for 64-bit and x86 is for 32-bit) 4. Follow the instructions UNINSTALLING ------------ 1. The device must be plugged in 2. Run Device Manager 3. Locate the device you want to uninstall 4. Right click on the device and choose "uninstall" 5. Follow the instructions SUPPORT ------- For technical support please visit the Silicon Labs support site: https://www.silabs.com/support ****************************************************************************** RELEASE NOTES FOR 6.7.5 (2017-10-13) Changes for VCP Driver ============================================================================== MCUSW-17 | IOCTL_SERIAL_GET_STATUS TransmittedCount fixed. MCUSW-19 | CP210x_GET_CONFIG_DESCRIPTOR_IOCTL returned byte count fixed. MCUSW-21 | Revert IOCTL_SERIAL_GET_COMMSTATUS behaviour to return cached | information (reverse slowdown reported with v6.7.4 in some | applications) | | Improve windbg logging, w.r.t. doing less when logging is not | enabled (say, Release builds), or when particular subsystem is | not enabled for logging. | MCUSW-110 | Windows 10 certified against RS2 (Creators Update). MCUSW-207 | In a failed initialization, discard a reference to dynamically | allocated memory once memory has been freed. MCUSW-234 | timestamp SHA2 Signatures with SHA2 timestamps ****************************************************************************** RELEASE NOTES FOR 6.7.4.261 (2017/01/30) - Device Guard compliant - CP210XFW-747: Add 3 new parallel PIDs one each for the single-, dual- & quad-port CP210x devices (to be distributed via Windows Update) - CP210XFW-741: Fix driver to use correct interface string index for the multi-interface CP210x devices (CP2105 & CP2108). Return iProduct string for other CP210x devices. - CP210XFW-713: Add protection against IRP_MJ_CLOSE coming before IRP_MJ_CLEANUP. In such case EvtFileCleanup callback was called with 0 FileObject, causeing a crash. Serenum is suspected of causing this, even though there is no proof except that it's present, was introduced recently and this crash was never registered before. - CP210XFW-691: Fixed race between timer activation and request cancelation during processing of read rwquests. - Changed raw WDF read request timer to our wrapper. - CP210XFW-693: bugfix: WMI command "wmic path Win32_SerialPort get Availability^, DeviceID^, Name" is unable to enumerate the port. - CP210XFW-686: EvtRequestCancel for wait mask IRP crashed because the request was already completed. It didn't serialize well with other places that can complete it. It looked like XOff IRP may have the same proble. This patch is adding an extra check into *all* other EvtRequestCancel functions to make sure this doesn't happen again. - Changed IOCTLs returning polled-cached MDMSTS to explicitly read the status. Use reg value DisableHwAccessInModemStatusIoctls to revert this new functionality to old behavior. - Improved debug prints. - SerialDbgPrintEx used 1K of stack for the string, reduced to 256. - Resolved many static Code Analysis warnings - Added accounting for data in chip's TX queue. Added translation of COMM_STATUS::ulErrors into SERIAL_EV_BREAK and SERIAL_EV_ERR. - CP210XFW-549, CP210XFW-536, CP210XFW-546: Generate events for IOCTL_SERIAL_SET_WAIT_MASK from COMM_STATUS::ulErrors. Can be disabled by DisableCommStatusPolling reg value. - Added spinlock around ModemStatus change detection. Refactored modem status event signalling to use common function. - Move passive level functions into the paged section. - MCUFW-740: Made device close operation wait for chip's Tx queue to empty. Added registry settings DisableTxEmptyCheckInClose and TxEmptyTimeoutOnCloseInMs. - Improve control transfer debug prints and clean up code, otherwise no functional changes. - MCUFW-740: Fixed EV_TXEMPTY to account for bytes in chip's Tx queue. - MCUFW-740: New functions to sync access to comm error storage from multiple threads. - Added DisableTxEmptyCheckInGetCommStatusIoctl reg value. - Refactor control request I/O. MCUFW-740: Fixed IOCTL_SERIAL_GET_COMMSTATUS. - MCUFW-740: Made device close operation wait for chip's Tx queue to empty. Added registry settings DisableTxEmptyCheckInClose and TxEmptyTimeoutOnCloseInMs. - CP210XFW-648: Set a three second timeout on WdfUsbTargetDeviceSendControlTransferSynchronously(). ****************************************************************************** RELEASE NOTES FOR 6.7.3 (2016/03/03) - Down-rev the verison of KMDF the driver uses (CP210XFW-591. Use version of KMDF natively included on Windows release) - Bug fix of blue-screen system crash (CP210XFW-575. driver tries to clear a Cancel Routine in a Request that doesn't have it.) ****************************************************************************** RELEASE NOTES FOR 6.7.2 (2015/11/23) - Unified Windows 7, 8, 8.1 & 10 support (XP, Vista and Server 2003 available in version 6.7). - ARM support added for Windows 10 and Windows 10 IoT Core. - Silicon Labs-specific Serial Enumeration driver silabenm removed in favor of the Windows "in-box" serenm. - UpperFilter Serial Enumeration driver not enabled by default - Updated to latest Microsoft build tools - Resolved /W4 compilation warnings - Resolved code analysis warnings - Added a registry value ControlHandShakeForcedSetBits that can force certain bits in the ControlHandShake variable to always be set. - Add SAL-annotations to API header files. - Bugfix an invalid memory access on device stop. - Standardize branding Properties resources across all deliverables. - Digitally sign all signable deliverables. - Rewrote driver synchronization for data transmission paths. - Resolve bugs arising from extended stress test. - Added diagnostic variables to
