Slightly OT: Need a USB-to-LPT adapter for Xilinx Parallel IV Cable

I am trying to run 2 ChipScope instances connected to two different boards. 
Unfortunately, Xilinx doesn't support more than one USB cable... I found in 
the past that you can actually have 2 cables running at the same time if one 
of them is parallel... My problem now is that my new Dell PC doesn't have a 
parallel port (neither does it have a serial port )... So I got myself a USB 
to Parallel adapter, but the ChipScope doesn't want to work through it... It 
seems that it is only good for a printer. It doesn't even create a proper 
virtual LPT port... So, I was wondering if someone knows of an adapter that 
will work?

Thanks,
/Mikhail

There are PCI parallel ports, and probably not to expensive.

Parallel ports used for other than printers often use the status
bits in unusual ways.  Writing the device driver to emulate a parallel
port used that way through USB would be more work than most want to put
into one.

PCI is out of fashion too :) This PC of mine only has PCI Express and only 2 
slots altogether. I guess I will go this route if I can't find another 
solution, but I hoped there is a proper USB-to-Parallel adapter somewhere...

NO way.

cable III/IV will **NOT** work over USB2LPT adapter

It would if one made a true emulation of a parallel port, including
the virtual device driver that would execute on I/O to the real
I/O port.  I agree that isn't likely.  Though many printers do
bidirectional I/O that would require the hardware to do some of that.

Even if the adapter would work, it would crawl like a snail. Bit-banging via
USB isn't a good idea.

I had a similar problem with my MacPro. It only has PCI Express, and I 
had 2 parallel dongles, one for HyperLynx and one for MXE. The HyperLynx 
people swapped my parallel dongle for a USB with no problem - they even 
FedEx'd it to me at their own expense. Xilinx refused to do the same for 
MXE. I use the LF652KB PCI-E parallel port board from Axxon.

They also make a parallel port/ serial port board for PCI-E.

We have tried a lot of USB-Parallel adapters for our Chameleon POD.
No result. Why, the USB-to-parallel are dedicated for parallel PRINTER 
port !

Do you have PCMCIA, use the Quartech SPP-100. It work nice for your 
Chameleon Pod !

Mikhail,
How about using VMWare to run another instance of Chipscope? Maybe that 
would work, you can try their software for free. I've not tried this.
