That'll depend on the model... Which is it? What are its PCI ids? If a PCI device, you can look it up with DCPIManager app, if it's a USB device, you should see in in SysProfiler.

 

Or extract an IOReg with IORegistryExplorer app and post it.

Oh good, it is supported, just need to patch the DSDT. Run this and export the IOReg as Hervé mentioned. Compress and upload it here.

 

update: Hmm, according to the 3340 DSDT, it's already patched to RP05?

Check your BIOS to see if it's enabled.

Thank you Jake!  Worked like magic.

 

Question though, what is the difference between /Volume/EFI  and /EFI?  When I copied the dsdt.aml, I used clover configurator to mount the EFI partition.  Then dropped the file in /Volume/EFI/EFI/CLOVER/ACPI/patched/

I always thought I'm supposed to use the one mounted by clover configurator, which shows up in finder and it's /Volumes/EFI.  If I just go /EFI, there's no 2nd EFI in the path.

 

$ ls /EFI/CLOVER/ACPI/patched/

ssdt.aml


$ ls /Volumes/EFI/EFI/CLOVER/ACPI/patched/

DSDT.aml ssdt.aml

 

so you see the one I see mounted in Finder is the 2nd one with /Volumes/EFI/EFI etc
