Whistler WS1095/WS1098 USB serial driver (INF, 2018-08-20)
==========================================================

WHAT THIS IS
------------
The WS1095/WS1098 USB driver that Whistler published on its downloads page
(zip uploaded 2021-10-20; the INF inside is dated 2018-08-20). It is a single
Windows INF file, derived from Microchip's CDC template (its DriverVer line
still reads 11/15/2007, 5.1.2600.0), that binds Windows' own usbser.sys to the
scanner's serial interface:

    USB\VID_2A59&PID_000E&MI_01  ->  "Whistler WS1095 Serial Device"

The scanner is a composite USB device: its memory card appears as a card
reader without any driver, and this INF is needed only for the serial port EZ-
Scan and the firmware updaters use. EZ-Scan's installer places the same driver
in its Drivers folder, so this standalone copy matters mainly when Windows has
lost or replaced the driver.

APPLIES TO
----------
Whistler WS1095/WS1098.

The hardware ID in the INF is model-specific; it will not bind to other
models. An un-upgraded GRE PSR-800 uses GRE's own INF (GRECOM_PSR-800.inf,
USB\VID_0C97&PID_0008&MI_01), which is installed by GRE's EZ Scan Digital.

BEFORE STARTING
---------------
- A Windows PC and the scanner's USB cable.
- On Windows 10/11, the INF is unsigned (it names a catalog file, mchpcdc.cat,
  that is not supplied). RadioReference owners report needing to boot with
  driver signature enforcement disabled to install it. A WS1088 without the
  driver appears only as a card reader.

    Whistler's zip containing WS1095-Scanner-Drivers.inf (dated 2018-08-20):
    a Windows INF that binds the stock Windows usbser.sys driver to the
    scanner's serial interface, hardware ID USB\VID_2A59&PID_000E&MI_01,
    device name "Whistler WS1095 Serial Device".

INSTALLATION
------------
 1. Unzip the file to a folder.
 2. Connect the scanner by USB and switch it on (or connect it in the state
    EZ-Scan expects).
 3. In Device Manager, find the scanner's unknown serial/CDC device (the
    card-reader half installs on its own).
 4. Update driver > Browse my computer > point to the unzipped folder. Accept
    the warning about an unsigned driver if Windows offers it; if Windows
    refuses outright, restart with driver signature enforcement disabled and
    repeat.
 5. The device appears under Ports (COM & LPT) as the name above. Note the COM
    number for the CPU updater.

The exact Windows prompts depend on the Windows version and were not recorded.

VERIFYING
---------
Device Manager > Ports (COM & LPT) lists "Whistler WS1095 Serial Device
(COMn)". EZ-Scan connects to the radio without a port error.

IF SOMETHING GOES WRONG
-----------------------
- Only a card reader appears: the serial interface has no driver. Install as
  above.
- Windows Update replaced the driver or only some USB ports work (a known
  complaint on this platform): reinstall this INF on the port in use.
- The port exists but EZ-Scan cannot talk to the radio: close any other
  program holding the COM port.

DOWNGRADING
-----------
Nothing to downgrade: this is the only driver version Whistler published. To
remove it, uninstall the device in Device Manager.
