Test Feedback: I have run some tests to ascertain why my iPad only charges for about 5 minutes when connected to a USB2 port on my rig
after I implemented RehabMan's fantastic fake EC and USBX patch on my GA-Z170X-UD3 build. Please note I stumbled across this patch quite by accident earlier today.
For what it is worth here are my findings :
"Umbilical cording" my iPhone, via a USB2 port poses no charging problems whatsoever, even during periods of extended sleep.
It does not matter what settings are present in "Clover config.plist Devices USB". As a result I unticked everything in that area ie. inject, high power and fix ownership.
Now to my iPad:
This device only charges for a few minutes, after which it informs me, via it's charging status indicator, that it is - not charging - . It does not matter what settings are present in "Clover config.plist Devices USB" Consequently I left them ALL unticked as they do not seem to affect USB operation at all.
Then I tested my iPad on a USB3 port and voila, it worked.
Conclusion or findings:
USB2 ports are not capable to supply the power which is required by the iPad, with the iPad disconnecting itself automatically from a USB2 "power source"
The iPhone on the other hand is quite happy with the power - current - that is available on a USB2 port and charges merrily until the batteries are at full capacity.
When connecting the iPad to a native USB3 port it however charges without problems or interruptions.
In my opinion, that stands to reason as the specification for USB3 ports provide for higher power delivery compared to USB2 ports. Indeed the charger that was supplied with my iPhone is rated at 1 amp whereas for the iPad the charger is rated at 2.1 amps.
Hoping that this feedback will be useful for those struggling with this issue.
Thanks and appreciation go specifically to RehabMan for providing and documenting the solution to this problem in such a concise and detailed manner so that even I could implement the patches without wrecking my brain into extinction
I just wander what the size of the hackintosh "family" would have been had it not been for RehabMan's efforts and inputs over the years, his excellent technical inputs and patience with some users, are just admirable.
Not true. USB 2.0 is capable of Charging a iPad but depending on if AAPL Values are injected and EC Controller is implemented. Charging a iPad on USB 2.0 on both of my Desktops works fine.
