Bluetooth Dongle Loses Functionality on Windows 7

I have a bluetooth drawing tablet that I use with my laptops, but I'm unable to get it to work consistently with my Windows 7 laptop. The problem seems to be with the USB dongle.

I can initially connect my device, but after some time with the tablet powered off, the laptop is unable to find the tablet again until I unplug the dongle from my laptop, then plug it back in.

Is there a fix for Windows 7 putting the dongle "to sleep," so to speak?

Thanks,
Spacer

Hi,

try looking in power options and disable usb selective suspend, this might help.
(go to advanced power options for the plan you are using)

If not consider trying another dongle, but this should help.

start->run->devmgmt.msc->OK

explore the tree and find your BT device.
right.click it and select properties.

Check if there's a "power saving" tab. If it's there, adjust the options accordingly.

Thanks for the responses, guys.

I tried hax1's solution first. I found the settings in Power Options, and changed them, but I'm still having the issue.

ienaxxx, I looked in Device Manager and found the Bluetooth devices, but they have no power settings.

The device appears to be working, it's green status light blinking, but even with the USB settings set to power continuously, I need to "wake up" the device by unplugging it, then plugging it back in.

Thanks,

Then there's a problem with the device itself or with the device driver.

Try to search for updated drivers / firmware from the manufacturer site... pay attention: download just verified updates that surely works with the tablet

I've got a couple each of the tablets/dongles, and they're doing the same exact thing. I downloaded the latest release (stable) driver from the manufacturer's website before I even started.

Looks like there might just be compatibility issues. Guess I'm stuck contacting the manufacturer.

Thanks anyway, guys.

try another thing -> remove the tablets batterys or replug its power source so you know if the error comes from the pc or the tablet!

oh and of course try uninstalling the manufacturer's driver and use the default windows one, those sometimes tend to work better! (you can do that trough device manager) and as I said before also try another dongle, might just be an incompatibility or something ...

I've tried the power source... it definitely looks like the laptop is the cause. I tried another dongle as well. I also tried checking services to make sure the Bluetooth service wasn't crapping out on me.

I'll give the Windows default drivers a shot.

Thanks!

Just thought I'd check in and close the question. Sorry about the delay... due to the difficulty of the situation related to the lack of urgency in getting this thing figured out, the project was put on hold.

I finally tested out the default drivers, and the device didn't show up in the list of discoverable devices at all. I also contacted the manufacturer, and you can probably guess how that went.

I've decided to go with another model tablet that I know works with our equipment. Thanks for the responses, anyway.
