their can be a number of reasons but this is the
most common
as quoted from ftdi web site
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 USBView utility
from the FTDI web site. These
can then be checked against the VID and PID entries in the driver INF files. If
they do not match, that driver cannot be installed for that device without
either re-programming the device EEPROM or modifying the list of VID and PID
numbers in the INF files.
Please note that only your company VID and PID
or FTDI's VID (0x0403) and FTDI PID issued for use by your company should be
used in the EEPROM and INF/INI files.
i am presuming that because you have built the pcb that the eeprom
will not be programmed with a default VID & PID , as is the case with the
pre built convertor cable .
are you using windows xp or windows 2000
?

Hi
,
I could not get
TTL-232R-3V3 USB - TTL Level Serial Converter cable in China,so I made the
cable myself according to usb_flasher.sch and usb_flasher.brd download
in http://cvs.savannah.gnu.org/viewcvs/paparazzi/paparazzi3/hw/in_progress/.When
I connect it with computer, Winxp found an unknown usb device but failled to
intall the driver(download from
http://www.ftdichip.com/Drivers/CDM/Win2000/CDM%202.00.00.zip). I don't known
why. Is usb_flasher.sch and usb_flasher.brd have some problems? How can I
do?
Another question is, I
can not get mlx90247-dsa , can I replace mlx90247-dsa with
tps334\3161
in ir_dual board?
Good
luck,
Longxin
Wei
