Unfortunately some of these USB to legacy adapters seem to have been designed with more optimism than engineering knowhow.

It may be time to trade in that old printer.

it's all about using the LPT port for controlling some (leds , motors) , but the problem is how I can deal with the the Lpt that haven't any IRQ or Port address .
best regards .

AYHAMm, did you figure out a solution to this? I am running into the same problem. I use USB-serial adapters all of the time, so I thought an LPT adapter wouldn't be a big deal, but it doesn't map like an LPT.

Thanks,

actually , you should make sure that the device exist in the device manager or not (lpt1) and then you should use the visual basic code :

open "lpt1" for output as #1
output #1, 111
close #1

the main problem is : - the usb-to-lpt didn't have a IRQ
-the usb-to-parallel didn't designed for taking a commands
-finally , you should give the device (25 pin) a feed back between the common and the status pins

i have the same problem, i want to run a Dongle on LPT1. Looking at my system, the usb 2 parallel installs itself as "USB printing support" instead of a line printer port. i'm hoping a PCIE card will solve my problem
