      Hello, I would like to ask if you have noticed the instability of the virtual serial port drivers created by microKEYER (MKII) version 8.0.7 in Win7 64bit environment. After updating from ver. 7.7.1 to 8.0.7, my system started to 'freeze'. Usually during the PC shutdown process and occasionally during the USB router shutdown.

      During the system logout, a blue screen appeared at irregular intervals in all cases indicating a critical error of the system driver evserial7.sys.

      After uninstalling and returning to the previous version 7.7.1, the system seems stable...

      I have also noticed unstable behavior under Win XP. For example, if the PC goes to sleep, the router will not connect to the device.
      After restarting the PC everything is OK. This error appeared only with the last version from December.

      microHAM programmers have confirmed that the Router 8.0.7 instability
      is due to bugs in the FTDI hardware drivers - specifically FTD2XX.DLL
      version 2.8.14 but the issues exist in all 2.8.x versions of the FTDI
      drivers. Unfortunately, there is no current replacement for the
      defective DLL *and* Router will need to be recompiled when FTDI
      releases a stable replacement.

      Until FTDI release a stable driver, the programmers are working he a
      *BETA* version of Router that will use version 2.6.0 of the FTDI
      drivers (the same drivers used in Router 7.7.1). When that version
      is ready it will be announced here - it *will not* be available for
      automatic installation through Router. I have no target for the beta
      but would guess it will be available before the end of the month – it
      it is necessary to remove developmental and debugging code from the code
      base before preparing any Software for release.

      Users who can't wait can reinstall Router 7.7.1. To do so it will
      be necessary to follow a special procedure:

      1) Open Router 8.0.7
      2) delete all virtual ports (Virtual Port | Delete All).
      3) then close Router.
      4) Open Windows Device Manager
      5) right click on each "microHAM USB Device" entry and
      select *Uninstall*. Check the box that says "Delete the driver
      software for this device"
      6) Close Device Manager
      7) select "Uninstall USB Device Router" from the Uninstall folder
      in the microHAM Folder of the Windows Start menu (do not use
      the Windows Control Panel)
      8) Disconnect *ALL* USB devices
      9) Reboot the computer (do not allow the computer to sleep or
      hibernate). This must be a cold boot to remove *all* old drivers
      from memory or the new drivers will not install properly.

      10) After rebooting, download the Router 7.7.1 installer from:
      http://www.microham.com/Downloads/urouter_release_07_07_01.exe
      11) Without connecting *any* USB devices (except keyboard and mouse)
      run the Router installer to reinstall Router 7.7.1. Connect *only*
      the microHAM device when prompted to do so when the installer is
      finished.
      12) When you have connected the microHAM Interface, you will need to
      manually restore the proper firmware (Device | Upload Firmware):
      microKEYER II – v 4.6
      digiKeyer II – v 1.0
      MK2R/MK2R+ – in 5.7
      micro2R – v 1.2
      Station Master – in 2.8
      13) after updating the firmware if necessary create your Virtual Ports
      and Configure Router 7.7.1.
      14) After your configuration is complete, close the Router to save it
      changed to the Windows Registry.
      Restart Router and reconnect any other USB devices one at a time
      while checking for conflicts.

      *NOTE* If you reinstall Router 7.7.1 or the forthcoming beta, you *MUST*
      disable Windows Update or set it to *manual* updates (so any update is
      manually selected). Windows Update will attempt to replace FTDI driver
      version 2.6.0 used in 7.7.1 with the current defective driver.

      Thanks for the info from the Yahoo forum. The unstable behavior manifested itself again today right after transitioning from hibernation mode to normal mode. The blue screen reported a critical error in the system driver 'evserial.sys' (ELTIMA Software, version 6.2.41.0). After a cold restart, the system booted without the need to enter login credentials, the drivers for microHAM mK II did not activate. They had to be activated manually.
