We experienced several problem when the parallel on host was used with a sample parallel cable or via the wiggler interface.
To avoid them an USBTap can be used.
For details, please have a look to our web site:

Some customer meets a problem similar to your issue due to the voltage of the Parallel port.
See below details:
Customer engineers examined the parallel port and found that the voltage supplied to the wiggler through the parallel port was about 1v. At least 3v must be supplied to the wiggler for proper operation.
Several users meet the same problem.
Can you please check it on your side ?

Try the following steps in the CCS Console window:
1. ‘show wdv’ à"WinDriver V5.05b Jungo (c)2002 Build Date: Aug 4 2002 X86 SYS"
2. Start à Settings à Control Panel à System à Hardware à Device Manager
Ports à Printer Port(LPT1) double click on this and on the window go to the Resources tab.
Look at the I/O Range. The first I/O range is the address of the parallel port.
3. delete all
config cc parallel:0x0378
After doing this you should connect to the board without any problems.
This error was appearing when a customer would try to connect to the debugger.
