LK202-24-USB - Win98 driver problem

Russ B · Post by **Russ B** » Fri Mar 07, 2003 3:01 pm

Please help a newbie!

Although the device in Win98SE is installed and is listed in Device Manager as both COM3 and the USB device, no software can connect to it as they cannot see the device!

So, LCDC on setup goes to COM1... not found, COM2... not found, and back to COM1...

Display Tuner only has COM1 and COM2 in the drop-down box.

Tested on a fresh Win98SE build too, and still didn't work. Tried the updated driver posted recently, and that didn't work either.

All drivers and firmware (esp. motherboard and chipset) are the latest versions on the PC.

Tried on a Win2K machine, and works like a dream! But I need this fantastic hardware to work on my Win98SE PC.

Help!

ok, try this. Go to the download section and there is a program called Alpha Demo, try it. Windows 98 testing was light, but it should work.

Thanks Henry.

The Alpha Demo could communicate with the screen OK. However, I'm guessing that this is because all of the configuration is manual, rather than querying the installed 9x driver which doesn't seem to report available ports properly(?).

Is a driver update imminent to address this issue?

LCDC and Display Tuner both look into the registry for COM ports. I wonder if Win98 treats them differently. And how.

Maybe try shuffling your COM ports? Make port 2 port 4 and port 3 (the usb lcd) port 2? You should be able to do this in the device manager...

Thanks Rob: don't know why I didn't think of that!

I can confirm that this workaround is successful, although it's a bit fiddly!

1) Go to Device Manager and change the COM port for the USB device to COM2 and change the baud rate to 19200
2) Remove the standard COM2 from the device list (if you don't need it)
3) Start LCDC. Will detect and connect, but will stop with an unknown device error!
4) Go to the config screen and select COM2, and the LK202-25-USB screen type
5) May need to restart LCDC
6) Success!

Glad to hear you got it working, win 98 doesn't handle its com list very well...
