Hallo Ruud and the list,

While I have no practical experience of USB to parallel converters, I 
wouldn't expect much from them. Recently I bought two cheap USB to RS232 
converters: one HL-340 based and one PL-2303 based. I managed to get the 
HL-340 to speak to a serial EPROM programmer, but failed miserably to use 
both with C2N232I which was my intended use. I have looked up the matter and 
there are several factors such as choice of chipset, whether the adapter 
also have voltage level converters onboard, of course drivers and more. 
Since not even serial communication seems to be possible to "get right", I 
think you can look for a long while to find a USB adapter that better 
simulates a parallel port.

Then again, there may be some people with experience of the X-series cables, 
connected to modern computers via USB adapters. I know a few years ago it 
was pretty much hit and miss if you tried to wire up e.g. an XE1541 via a 
USB adapter.

Best regards

Anders Carlsson
