troorl Posted October 5, 2021 Share Posted October 5, 2021 Hi. It's my first experience with this laptop. I'm using the default Intel combo card with Jake Lo's E7x70 pack. WiFi works well, but Bluetooth is not detected at all, despite all the right kexts in place. I mapped USB ports using USBMap. The number of ports is limited now, everything works including the webcam. Yet there is no sign of Bluetooth. It didn't show up in USBMap at any point. I'm using Big Sur and the latest BIOS if it makes a difference. Does someone have any ideas? The list of the kexts and config.plist are down below.

Moderators Jake Lo Posted October 5, 2021 Moderators Share Posted October 5, 2021 If it didn't show up in USBMap, then it's not detected properly. Re do your USBMap kext. You might have to enable USBInjectAll.kext to pick up all the ports so you can create USBMaps. Did you check under USB in system report? Link to comment Share on other sites More sharing options...
troorl Posted October 5, 2021 Author Share Posted October 5, 2021 Yes, I've done all that, following the guide. With USBInjectAll and xhciportlimit=true, Bluetooth doesn't show up anywhere, including the USB section in the System Report. Just checked with Hackintool to be sure, no luck. Initially I used a different pack with an older OC, and at first Bluetooth worked (or at least it was detected). Then after one of the countless iterations it just disappeared. Interestingly enough, when I return to that exact pack, Bluetooth still doesn't work. And of course it's enabled in BIOS, I checked. It feels like some kind of magic is involved. I used to experience something similar on E6430, specifically with Bluetooth. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 5, 2021 Moderators Share Posted October 5, 2021 disable xhciportlimit. I think it was broken some version ago Link to comment Share on other sites More sharing options...
troorl Posted October 6, 2021 Author Share Posted October 6, 2021 I'm not sure how this works, but I solved it by loading Ubuntu. Bluetooth was available in it, and after rebooting to macOS it showed up in USBMap under HS08. I think it might be some soft airplane mode that was turned on but couldn't be turned off in macOS itself. And then Ubuntu reset it. I don't know, just a theory. Unfortunately I discovered another unrelated issue. When the laptop is charging, the trackpad is practically unusable. Oh well... Link to comment Share on other sites More sharing options...
