Windows 98 Installation Guide Troubleshooting Windows 98 cannot find drivers for my device This error can occur if the VID and PID programmed into the device EEPROM do not match those listed in the INF files for the driver. The VID and PID programmed into the device EEPROM may be found by using the the VID and PID entries in the driver INF files.
Windows 98 forces a reboot after installing a device This problem can occur if an application is accessing a file while the New Hardware Wizard is trying to copy it. This usually occurs with the FTD2XX.DLL file. If installing a D2XX device, selecting not to restart the computer then unplugging and re-plugging the device may allow the device to function properly without restarting.
Windows 98 Installation Guide Driver installation fails and Windows 98 gives error code 10 Windows error code 10 indicates a hardware error or failed driver installation. This error may appear if a device has insufficient power to operate correctly (e.g. plugged into a bus powered hub with other devices), or may indicate a more serious hardware problem.
FT232BM or FT245BM device hangs randomly during operation under Windows 98 This is not caused by the driver, but is a hardware compatibility problem. Some newer USB 2.0 hubs and host controllers can be susceptible to noise and can cause random device failures. This can be overcome by fitting 47pF capacitors to ground on the USBDP and USBDM lines on the USB connector side of the 27W series resistors.
Windows 98 Installation Guide Windows 98 complains about missing .CAT files Files with the .cat extension are signature files issued by Microsoft that indicate a device driver is WHQL certified. If a driver is not certified, there will be no .cat files available. When installing drivers in Windows 98 or Windows ME, the user is prompted to locate the .cat files if the operating system cannot find them.
Windows 98 complains about missing ftccomms.vxd file This can occur when the USB Composite driver has been installed if the user has not browsed to the location of the driver files. If this message appears, do not skip it but browse to the driver file location.
Windows 98 Installation Guide Windows 98 installs FT2232C device as VCP even though D2XX drivers are selected in the EEPROM This problem can occur when the device EEPROM is set to use D2XX drivers and the user is attempting to install using the combined FTC drivers for D2XX and VCP for Windows 2000 and Windows XP.
