Mavericks installed but with bluetooth issue

[stevensun1982]

I clean installed Mavericks successfully today and everything seems working well except bluetooth.
I'm using a BTD 300 adapter which works fine on my mountain lion machine.
The adapter is on and can connect to my devices but the devices kept on connect and disconnect.
Tried modify .kext with the vendor id and product id, but doesn't help.

Anyone's having similar issues?

I am having the same issue but with the IOGEAR GBU521.

Anyone's having similar issues?

Yes. After installing Mavericks, my Trackpad connects at startup, but disconnects after sleep, and won't connect again. After disconnecting the dongle for a moment it connects again.

I am using an Apple BT module A1114, that worked flawlessly under SL.

No idea what I could do to resolve this.

No guarantee this will work but I resolved issues with my Bluetooth this way.

Try rebooting with UseKernelCache=No

and see if it helps.

If not try also removing the devices from Bluetooth preferences, putting them in afresh and reboot with with UseKernelCache=No.

The other thing that helped my Bluetooth functionality was attaching it to one of the Intel USB 3.0/2.0 ports on my Z77X-UD5H

edited to add
afterwards return to UseKernelCache=Yes (assuming you were using that in the first place).

Thank's, the Gael.

I have tried around a bit with the Boot Options. Now it seems to work fine. Maybe it has been for activating "Generate CPU States", but I am not sure about that. Not sure if I had kernel cache deactivated before. Might be that one, too, as you suggest. I pase my boot.plist below.

Klaus, what I had experienced was that if I made changes to the machine as I sometimes do - such as adding devices or changing bios settings I would experience these issues with wake from sleep - I found that if i reboot with UseKernelCache=No it would generally resolve the issue and I could then revert to using UseKernelCache=Yes.

Not sure why it works but thinking it could be because generally on a Apple machine the bios and devices don't change and when on a Hack they change the system does not cope with it - clearing the kernel cache seems to resolve.

The problem occurs with a new Mavericks install; Mavericks uses AppleUSBXHCI.kext for USB and ML uses AppleUSBEHCI.kext. Without a rebuild of cache, the OS is looking for the USB device in the wrong place.

Easy way: DPCIManager/Rebuild Cache

thank's for the tip. Now BT is awaking well, but for future issues it will be useful.
