I concluded it must have been some kind of loose connection inside and installed the bluetooth drivers from here But, my laptop decides to surprise me today and the Broadcom Bluetooth card suddenly shows up on lsusb after a suspend session. I thought maybe that was a hardware issue and I'd solve it later by checking if the card is seated properly or not. lsusb does not show the broadcom bluetooth (for others in the forums with the same card, it did) Online forums suggest that although bluetooth and wifi reside on the same card, the bluetooth connects to the USB bus. I don't want to buy a separate bluetooth dongle since my USB ports are pretty occupied already with the mouse and USB WiFi dongle and what not. My problem arises when I want to use bluetooth. Note: USB WiFi card uses rtl8812au and has driver support from aircrack-ng. The USB WiFi card started working when I removed the broadcom driver. Giving up, since I don't use that WiFi card anyway, I tried using my USB WiFi dongle and that also didn't turn on while the broadcom driver was installed. rfkill shows that the card is hard blocked. The WiFi appeared to be recognised but it doesn't turn on. I installed it and WiFi, and bluetooth didn't work. The recommended driver for the card is the bcmwl-kernel source. I installed Zorin-OS throughout the system recently and it's been going awesome except for one problem. I have an integrated (Bluetooth+WiFi) Broadcom BCM43142 PCI card on my HP Laptop.
