Hi, I have a problem with MSI Z87-G43 MB and a haptic device Sensable Phantom Desktop that has a parallel port connector.

The device needs an on-board paraller port with EPP support. When I run calibration application for the device which initiates connection using paraller port, my computer hard resets (no BSOD, no minidump, no kernel panic). I tried every possible mode of paraller port in BIOS settings with EPP support (ie. 1.7/1.9 and ECP/SPP).

The problem seems to be in the HW part because the same thing happens in Windows 7 x64 and Linux CentOS x64. The computer resets immediatly when I run calibration software. In one case, in Linux, it actually worked without EPP (i.e. [PCSPP,TRISTATE]) for a while. The calibration app printed out warnings about EPP, but it hard reset after few seconds anyway.

Sometimes, after the hard reset, the computer does not even start until I unplug the parallel cable from the device. The power led turns on, DVD drive starts spinning and it resets after 1-2 seconds again and again until I unplug the cable from the device.

I updated the BIOS to the lastest version. Tried different IRQs and still no luck. The device works on older computer perfectly. Any idea what might be the problem?

Thank you!
 
This is a long shot but what PSU (Power Supply Unit) are you running on your PC?

Haptic devices are noted for a comparatively high Wattage requirement and if your PSU is only just powerful enough for your system it's possible the device is overloading the PSU resulting in system restarts.
 
It is Corsair CX Series CX750 V2 750W. However, the haptic device has its own power supply Skynet electronic SNP-A079.

We also tried different electric plug sockets - no difference.

Thanks
