WD_Open fails intermittently
« on: May 02, 2012, 14:07:07 »
Occasionally, my call to WD_Open fails. If I call WD_GetErrorInfoMsg, both the error string and info string are empty. Does anyone have any idea what could be causing the problem?

I am using the PCIe card under Win XP Pro SP3.

I don't know if this has any bearing on the problem but all USB ports have been disabled in harware manager for security reasons. Could this upset WD_Open()?

Does this happen after a power-up? Could you check device manager to see if you have two PCIe COM ports. The PCIe interface on that board uses a dual COM port chip.
