Apple branded bluetooth module in USB hub - Solved Sleep

[mikeetastic]

The diodes will go on the positive wires. Take note of the cathode and anode sides.

Red=positive
Black= ground

The other two I'm not quite sure and you may have to test it. Wire everything together soldering the green wire from the USB cable to the data- cable from bt module (blue wire) and the white from the USB cable to the gray of the module, D+. If it works then no further work is required. If not then swap those data wires. Good luck.

what do you mean by "Take note of the cathode and anode sides"

im off to my local radioshack in a few to buy a soldering iron and diodes (hopefully i can find one)..

my first time soldering so hoping it goes well later

*it goes like this right*

Thanks thanks..

Check out the link. Their should also be a diagram on the diode packet itself. Basically a diode only allows current to flow in one direction while also reducing voltage. Current flows in through the Anode and out through the cathode. The set up looks right also were just not sure of the data wires so well test that.

Thanks thanks..

i think i already broke my module coz no matter what combination i do windows says USB has malfunction and OSX doesn't detect anything under system profiler..... i also notice that the module gets too hot to touch?? or im not doing it right??

here's what i did

 

[mikeetastic]

working now yey! macaddictcr's module and mine are the same so i just copied what he did on the first page - i used an old Belkin 4 port USB hub until i can make the diode method working

system profiler on a MBA

good to know that the module is still working..

now anyone has an idea why the diode method is not working for me???

 

[mikeetastic]

yey! diode now working..the reason it's not working is because

BLACK = POSITIVE / GREEN = GROUND on the BT module

*pretty* it's my first time soldering

system profiler

Thanks sumsaykra-z and the thread starter for the help

[quote="sumsaykra-z":2b92rijl][quote="the_gael":2b92rijl]Is it possible that the machine will remember which was the first port the module was plugged into. I have just discovered mine only works on the one port on the front. Luckily it works perfectly there. Does not work at all on the rear ports but might revisit that with a bit more knowledge of what voltage the rear ports are outputting.

Initially, for testing purposes, I had the module spliced into a usb cable and it worked on every usb plug I plugged it into. I know have it spliced into a usb header cable and plugged directly into the motherboard and it's working like normal. So in my situation nothing was remembered and it just worked. It's weird that you're getting this issue. Typically usb is standard 5v so if anything the module is getting too much. How sure are you those ports actually work. Dumb question but I had to ask [/quote:2b92rijl]

Valid question - but brand new board and everything else i.e. USB Hard Drives, USB Storage Keys, USB Webcam... all work.
Agreed, it is strange hence my question about whether the OS stored info on which port the USB Module was associated with.[/quote:2b92rijl]

I have now taken the front panel out of the equation. I created a cable to attach to the USB headers on the board (there are 3 available 10 pin headers - each giving two usb ports) of these the module only works with one USB Port but it no longer sleeps. The one it works with is USB Header 1 and only works on the pins 2,4,6,8. If I connect the cable to any of the other connectors on the board the module is not recognised and this is the same whether I use no diode, 1 diode or 2 diodes. This is where it was connected to via the front panel usb port. My Bluetooth module is A1114

A point to notice which I suspect may be relevant is that on my board the USB Header which works is on F_USB1 which is coloured red and therefore different to the other two headers. The manual explains that only this header can support On/Off Charge should the machine be in S4 or S5 mode. It would make sense to me that this functionality could affect voltages. Maybe I will ask Gigabyte support?

If anyone with electrical expertise can help me understand this it would be greatly appreciated.

OK I have it working but I don't understand why!
I wiped my hard drive - I keep my user accounts on a large HDD and system on an SSD so it doesn't take me very long. I then dismantled my USB Cable and attached the Bluetooth A1114 module directly to the F_USB1 header using pins 2,4,6 & 8.
I also fitted my Apple Wireless N mini PCI-E card in its mini PCI-E to PCIE adapter.

I rebuilt using Multibeast 3.4.0 and Wireless and Bluetooth work perfectly and Bluetooth Keyboard works in Chameleon. I did not fit the diodes to the positive line.

I don't understand why it works now but would not auto-sleep when I fitted it there after having originally had it in the front USB port.

I suspect that the reason I had no success on the other USB headers is that I was unaware that diodes ran in only one direction. I bought a pack of 100 diodes and there were no instructions although I do see that they are packed with a white strip of tape retaining at one end and a red strip at the other. Also on the cylinder of the diode one end has a grey metallic paint band around it. Maybe these are some sort of indicators that someone with electrical knowledge can tell me about.

The one issue I have is that the machine will not auto-sleep with an external USB drive (either USB 3.0 or USB 2.0) attached but that is not related to Bluetooth as it is the same with a normal USB Keyboard as well.

Incidentally if anyone is having issues with range after fitting the module inside their case - I have a dramatic improvement in range after fitting mine inside the case and connecting to the spare antennae on my MiniPCi-e to PCi-e Wireless adapter. These are widely available on ebay and are relatively cheap.

Just finished my BT hack using the voltage converter rather than diodes !

It works a treat and the range is crazy - I stopped being able to see the cursor before the range cut out !

I LOVE IT !!!!

IR module next !

Ah - could you elaborate on the voltage converter! I have mine working but it bugs me that it only works on one port! So I may have a go at the voltage converter!

Here's the guide I followed - I had to order the part from the USA to UK but it arrived quickly. I bought a double USB bracket that attached to an internal header and used that to connect to my motherboard.

What do you mean "one port" ?
