anor4k Posted August 18, 2016 Share Posted August 18, 2016 In El Capitan my Z77X-UP5 TH motherboard used to be able to output higher current power through the USB ports, so I could charge some devices. After updating to Sierra, it has since stopped working. It required DSDT to work properly, and didn't require the "High Current" option in Clover to be turned on (I didn't even noticed it until it stopped working). Was there a significant change to USB in Sierra that could have caused it? I'll attach both my vanilla and patched DSDT. Link to comment Share on other sites More sharing options...
H8TR Posted September 16, 2016 Share Posted September 16, 2016 Me too. Had it working without DSDT in 10.11 on a Z97M-PLUS. Allowed me to charge my iPhone up to 2100mA. Not anymore in Sierra. Link to comment Share on other sites More sharing options...
Stefan Milev Posted September 21, 2016 Share Posted September 21, 2016 I not only lost that, but also intel USB3 on GB Z77-DS3H. Link to comment Share on other sites More sharing options...

Bubble Posted October 10, 2016 Share Posted October 10, 2016 I not only lost that, but also intel USB3 on GB Z77-DS3H. Yes, in the same boat here, but on an Asrock Z77. I thought I had read a fix somewhere, but I can't find it anymore... Link to comment Share on other sites More sharing options...
Badruzeus Posted October 10, 2016 Share Posted October 10, 2016 This is not a good solution, but temporarily I use 10.11.6's IOUSB*.kext on Sierra 10.12.x for "Current Available (mA)". It's always better back up ur 10.12.x's Vanilla kexts first. Still waitin' 4 simple solution than this.. My mach just has USB2.0 Ports, not trying yet on USB3.0. 1 Link to comment Share on other sites More sharing options...

Oh, that's nice, I will give it a try. Does it work with SIP on? Link to comment Share on other sites More sharing options...

Riley Freeman Posted October 11, 2016 Share Posted October 11, 2016 Same problem here. It looks as if extra current is being provided for USB 3 devices, but not USB 2 ones. So while my USB 3 flash drive shows that it's getting extra current, my iPad shows 0. 1 Link to comment Share on other sites More sharing options...

Badruzeus Posted October 13, 2016 Share Posted October 13, 2016 extra current only available with apple device connected (iPhone,iPad,iPod) Ah got it, current available and extra current are different. LoL Link to comment Share on other sites More sharing options...
Riley Freeman Posted October 13, 2016 Share Posted October 13, 2016 That's the opposite of what I'm seeing. I'm getting extra current with a USB 3 stick but my iPad (which is only USB 2) isn't getting any extra current since Yosemite. Link to comment Share on other sites More sharing options...
anor4k Posted October 13, 2016 Author Share Posted October 13, 2016 Well, using 10.11.6's kexts worked for me It's not the best solution but works fine, and didn't cause any trouble. My "Current available" went from 500mA to 1000mA for every USB port, and USB3 ports give me extra current. My iPhone now uses 2100mA total current. Thank you badruzeus 1 Link to comment Share on other sites More sharing options...
Stefan Milev Posted April 5, 2017 Share Posted April 5, 2017 Hi guys, I know this topic is old, but did anyone find a better solution for this? I have two machines one with z77 and another with z97 both having this issue. I´m booting on both with Clover. There are cases that I need to charge my iPhone and this is going very slowly without the extra current option. Link to comment Share on other sites More sharing options...
