On my otherwise stable 32bit Windows 7 Ultimate Retail Asus P8H67-M PRO MOBO/Intel I5-2400/4GB system built in early April 2011, whenever I have my D-Link DPH-50U (also known as ATCOM AU-600) USB Analog Telephone Adapter for Skype plugged in, Windows 7 crashes when entering the Sleep state. Skype itself is not running when Windows 7 attempts to enter Sleep mode.
Other than the crash entering sleep with the DPH-50U plugged in, Windows 7 behaves without issue, and the DPH-50U works correctly when connected to Skype. If I unplug the DPH-50U, Windows 7 successfully enters the Sleep state without issue.
I have tried multiple workarounds without success such as installing the DPH-50U drivers
in different compatibility modes (e.g., XP SP2, Vista, etc), setting the installed DPH-50U applications in different compatibility modes, and using different system USB ports. I am using the most recent available drivers which are Vista 32bit capable.
I would like to leave the DPH-50U plugged in full-time to benefit from Sleep power savings without the hassle of constantly plug-in/unplugging the unit.
Any suggestions based on the attached log files would be greatly appreciated.
Thank you for helping.
