Hi,
I am trying to install
(two) USB to parallel (IEEE1284) adapters on a Windows XP
system to control some previously working specialized hardware (using
parallel ports on an ISA bus machine). I follow the info at
http://zone.ni.com/devzone/cda/tut/p/id/4478 about creating the INF/PNF
files. The INF file looks OK to me (has the correct VID and PID).
However, when I insert the adapter (ATEN UC-1284B) Windows recognizes
it and uses the Windows printing utility driver for it. It is as if the
INF file I created is ignored. I don's see the USB to parallel adapter
in MAX. I also have a USB hub on the "other" USB output of the computer
(for mouse and keybd).Of course under
System>>Harware>>DeviceManager>>USB
Controllers>>Drivers I see the device. I have placed the
INF/PNF file in
c:\windows\inf . I determined this to be %SystemRoot%\inf by going to a
DOS window and doing a "cd" to that location. This is urgent/time
critical as the equipment needs to be shipped internationally so
development time with it is limited. Thanks
Why are you trying to create your own .inf file? The procedure you mention is only for creating your own driver and using USB RAW commands. Surely the converter came with it's own driver and this is what you are seeing in the windows device manager. My suggestion would be to remove the .inf file (and the compiled version) from the system and reboot the pc. Then see if the new parallel port shows up in MAX. I've only had experience with USB<->RS232 converters but using those, the driver that comes with the device is all that you need.
