Windows 7: Bluetooth Adapter Fails on Wake

Bluetooth Adapter Fails on Wake

I've been scouring the internet for a while and have yet to find an answer to this problem.

Basically, when the computer goes to sleep, upon wake, the blutooth adapter does not reinitialize. It works fine on hibernate, and re-inserting the adaptor fixes the problem but that is a bit of a hassle to keep doing that to continue to use a simple bluetooth mouse.

I've tried both the default windows bluetooth stack aswell as the manufacturers stack, and still get the same issue with both. I am at my wits end trying to figure this out on my own.

Bluetooth Device: Cirago BTA-3210 Micro USB Bluetooth Dongle
Laptop: HP Pavilion dv7-1468nr Entertainment Notebook PC

One more example of why sleep mode in Windows is a horrible idea... Good Luck.

I'm experiencing this same Event on my computer. It happens only when I wake from sleep. Dell shipped an updated driver that, from my perspective, just reboots the BT stack. So the pain I experience is about 20-30 seconds wait time when waking before my BT keyboard reacts. On rare occasions I have to reboot. I used to be able to reset the notebook wireless (in bios that controls wifi and BT) then restart all BT related services.

I'm not using a BT USB adapter. This event is caused by the internal BT card from Dell. Dell calls this the Wireless 370 bluetooth minicard, however, it doens't present in msinfo32.exe in any such fashion. I think Dell is wrapping something from Broadcom.
