Bluetooth problem

[Menchen]

Hi, yesterday I opened up my laptop and inserted wifi card from taobao, and tried solder usb cable(probably bad soldering skill... Can I solder like one to pin 3,4 and other one on pin 5,6?). After replaced usbport kext I still cannot get Bluetooth working.. not showing in system information/ Bluetooth nor in usb. Wifi is working good. Also I noticed that touchpad is a little "soft" is it problem about battery screw (too soft )?

@Menchen Hi, D+ have to be soldered into pin4 and D- to pin5. These two pins are only two pins for USB protocol. I think there are two things you can do.

• Check whether there are kexts called USBPower or USBInjectAll in CLOVER/kexts/Other. If yes, you have to delete them.
• Go to Windows or use IORegistryExplorer to check USB ports. You can generate an ioreg file and send back to me.

I'm sure I have soldered at these pins, what I'm not sure is maybe it have a bridge with 3 and 4 ; 5 and 6....

IOReg after delete USBPorts, no USBPower nor USBInjectAll.

IOReg after reboot with USBPort (The one that supposed to enable bcm bluethoon)

IOR with USBPort.zip

I think soldering is ok... and what about trackpad? Is normal that trackpad is softer than before?

@Menchen In your IOR with USBPort, I see port HS02 is enabled, which is for WLAN_LTE USB. Technically, BT should work if you soldered correctly. Maybe you can go into Windows or other OS to verify that your solder process is successful or not.

For softer trackpad, I can help little. The driver VoodooI2C is from https://github.com/alexandred/VoodooI2C, and I have limited knowledge about how it works. You can create an issue at https://github.com/alexandred/VoodooI2C/issues to get professional help.

@stevezhengshiqi After booting into Linux, There is only one Bluetooth device, so It must be soldering problem (Or linux driver?). Also the intel one didn't shown on lsusb and lspcie....

About the trackpad, what I meant is that it's physically soft (a small gaps, and it move with little force without click ), Is it normal as we added antenna under it or it's just me?

Also it's safe to bridge when soldering pin? like 3 with 4 and 5 with 6..... Because I have no prior soldering experience and it's too small..

Thank you for your time.

@stevezhengshiqi I have tried to solder another time.. and I have made sure that the pin is correctly solder using a multimeter... I'm using the kext in wiki with SolderBT(md5 end with 08aaeadb2e1) and HS02 is not showing in ioreg(only 1,3,4 and 9 ,nothing plugged beside power source).. so maybe wrong kext or....
I will update full log ASAP as I'm currently using phone data without wifi... (btw I changed thermal paste and it solve the thermal throttles, at full load instead 100c, now it's 75c, and 5c differences in idle.)

Thanks you for your time.

Update:

Sorry about bothering you again.. it seem the download got corrupted. After reboot HS02 showed up.. this led me think that maybe it's my card issue... I will check it in linux..(and if no luck I think I will give up Bluetooth...)
