Windows 7: Win7 BSOD Entering Sleep with D-Link DPH-50U Skype VoIP ATA

Hi,




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.

Hello,

I hate to be the one to say this, but I'll just have to bite the bullet I guess. You're experiencing a driver issue, as you already know. Really, your only options are to keep on doing what you have been, or downgrade to an earlier OS such as Vista or XP.

I suppose there's a chance you could try installing drivers for some similar but newer device. If you're up for it, start downloading drivers for similar models, give them a shot.

So far a workaround for my Sleep Windows 7 crash problem appears to be working.


I added a PCI card with four USB ports, plugged in the D-Link ATA USB adapter into it, and made sure the motherboard BIOS power management had “Power on by PCI” Disabled --- and so far it works!


Windows 7 power management must go only as far as the PCI card, and does not/can not interact with the attached D-Link ATA.


Now the system goes to sleep without crashing. And during normal operation, Skype sees the D-Link ATA and all work together successfully.


Thank you for your suggestion that the problem was with the drivers. Yes, I think that is the problem.

Well glad to hear that; however the method, at least it's working for you!
