How to Fix Dell Inspiron 15 3542 - USB 2.0 Ports not working on macOS

Wi-Fi, Bluetooth, AWDL, Continuity and Location Services problems usually come from chipset support, kext pairing, privacy settings or network-location corruption. On Hackintosh systems, Location Services and Continuity depend on working Wi-Fi, Bluetooth, AWDL and correct AirportItlwm or itlwm/HeliPort behaviour.

Quick Checks

• Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
• Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
• Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.

Fix Steps

1. Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
2. Confirm the exact chipset: Identify the Wi-Fi, Bluetooth and Ethernet controller from System Information, Hackintool or Linux/Windows device manager.
3. Use the correct network stack: Match AirportItlwm, itlwm, HeliPort, IntelBluetoothFirmware and BlueToolFixup to the exact macOS version.
4. Reset macOS network state: Remove the current Wi-Fi service, reboot, add it again, then reconnect to a simple WPA2 network before testing advanced features.
5. Check privacy permissions: Open System Settings and confirm Location Services, Maps, Weather and system services are enabled.
6. Test Apple features separately: Verify normal internet first, then Bluetooth, then AirDrop/Continuity. Do not debug all three at the same time.

Verify It Worked

• Maps can locate you without falling back to a stale location.
• Wi-Fi reconnects after reboot and sleep.
• Bluetooth remains available after a cold boot.
• Console no longer shows repeated wireless or location daemon errors.

Rollback

• Restore the previous EFI if Wi-Fi disappears completely.
• Switch from AirportItlwm to itlwm + HeliPort, or the reverse, if the issue is specific to one driver path.
• Use Ethernet or USB tethering while testing so you do not lose access to downloads.

Original Question: "Dell Inspiron 15 3542 - USB 2.0 Ports not working"

Hope somebody can help me with this, I have already mapped my USB Ports using USBToolbox.kext and after installing an .aml file in the EFI to get my trackpad working, the USB 2.0 ports just stopped working and do not work at all. I have attached images from Hackintool showing only one Intel USB Controller and then an Image of Windows showing Multiple USB Controllers. I have also attached the EFI below. I honestly tried everything but nothing works but also for some reason the only port that works is the USB 3.0 port and it works perfectly fine with a USB 2.0 drive and a USB 3.0 drive. Thanks EFI: https://drive.google.com/drive/folders/1Gtg94QP1tpusbFdVmGrmPFUNI4vOGVf_?usp=sharing https://preview.redd.it/npn6pd4abg0e1.png?width=630&format=png&auto=webp&s=344f01b7531868d8dbe962950f316433930d98b4 https://preview.redd.it/2x8lvatabg0e1.jpg?width=544&format=pjpg&auto=webp&s=5c38d33c38dc95c6a2c39f0d111250b5c9b820c0 Specs: Make and Model: Dell Inspiron 15 3542 CPU: Intel Core i5 4210U 2 Cores 1.7GHz GPU: Intel HD Graphics 4400 WIFI/BT: Qualcomm Atheros QCWB335 (Wi-Fi works but Bluetooth doesn't) RAM: 4GB 1600MHz DDR3L HDD: WD Blue 500GB 2.5inch SMBIOS: MacBookPro16,3 OS: macOS Catalina 10.15.7 submitted by /u/overcomebus4316 [link] [comments]
