  1. I've managed to get hot-swapping to work now too. Attached is the SSDT. It needs to go into EFI/CLOVER/ACPI/patched The SSDT assumes your USB-C port is at RP05 which should be the case for 7490. @amthb0 with the 7390 may be fine too. I see it has one fewer USB-A ports than the 7490 so it might be different. If it is, let me know and I can probably sort you out. @Hervé is right, you definitely don't need this if you have a non-TB model. The only reason you need this at all on TB models is because the Thunderbolt port has its own USB controller - seperate from the USB controller than handles the other USB ports. SSDT-USBC.aml.zip
  2. I have a partial solution to this for 7490's with Thunderbolt. It does not fix Thunderbolt itself but it will allow you use the USB-C port as a USB port. I tested it with a USB drive, an Android device, a keyboard and a mouse. It does require the use of an SSDT. You can't seem to hotswap type-C devices itself. However, if you're using a type-C to type-A adapter, you can hotswap the type-A device. I'm not sure if this is of interest to anyone.
  3. I have a 7490 with Thunderbolt and followed Hervé's guide. I'm still on Mojave for what it's worth. I can confim I have the same issue with the USB-C port as reported here. I have a WD15 Dock which works fine on the USB-C port, althought it doesn't work if I hot swap it - it must be plugged in before I turn on the 7490. When plugging in a flash drive into the USB-C port, it doesn't pickup the drive at all. On the same machine but booted into Linux, it works fine. I was trying to get Thunderbolt to work myself but I've not had much luck. If I connect the 7490 to an iMac using Thunderbolt, it shows up as a Thunderbolt enabled PC. However it shows this before the 7490 even boots into macOS and I believe it's supposed to detect that it's a Mac connected when macOS is booted. If I boot the same 7490 into Linux with the Thunderbolt cable still connected to the iMac, the iMac shows it's an Ubuntu device connected. I can see a Thunderbolt 3 NHI PCI device at 8086,15d9 but it doesn't seemed to be properly loaded. It might need to be added to the config.plist but I'm not sure what sort of property keys and values it needs. I'd be happy to test anything if anyone else has any ideas. iMac with 7490 Connected running macOS iMac with 7490 Connected running Ubuntu Thunderbolt 3 NHI PCI Device IOReg showing the PCI device System Profiler showing no drivers loaded
