I need to connect to a parallel port device which uses EPP mode to communicate. However, I get an error "An EPP connection error occurred: poll : Interrupted system call". When I try to debug using gdb or use strace to find what is going wrong I don't this error and I am able to connect to the device. What is going wrong? How can I get this fixed?
[edit] I use linux. The device used is a haptics device connected to the parallel port. Opening of the device is done through the initialization routine provided by the haptic device SDK.
It is fixed now.
The problem was with the BIOS. We had to ship the motherboard back and got the BIOS updated and it worked fine.
