Resset Posted September 1, 2015 Share Posted September 1, 2015 Hello! I have a really strange issue with Samsung RC720 Issue. Everything was working fine since Yesterday. I have 4 USB 2.0 ports. 1st is working fine but the other 3 started to behave strangely. When I plug something to them my USB device keeps plugging and unplugging itself. I can't figure out what the problem is and I couldn't find any information. Here is my config:Samsung RC720HD3000 - 1600x900Intel Core i3 (Sandy Bridge)Clover EFI and custom DSDT.amlIf anyone experienced similar problem and found the solution I would kindly appreachiate sharing it Regards Archiwum.zip Link to comment https://www.insanelymac.com/forum/topic/307877-samsung-rc720-strange-usb-issue/ Share on other sites More sharing options...
Allan Posted September 1, 2015 Share Posted September 1, 2015 You can apply some patchs for USB in DSDT, and check the USB options in config.plist: http://clover-wiki.zetam.org/Configuration/Devices#USB Link to comment https://www.insanelymac.com/forum/topic/307877-samsung-rc720-strange-usb-issue/#findComment-2164915 Share on other sites More sharing options...

None of them worked. DSDT and config.plist are in the archive.

Resset Posted September 1, 2015 Author Share Posted September 1, 2015 No I haven't touched any system kext. I only operate on DSDT and clover config. I also do not use any rollbacked or generic kexts.

Allan Posted September 1, 2015 Share Posted September 1, 2015 You only have USB 2.0 ports right? Have you upgraded your OS X? Link to comment https://www.insanelymac.com/forum/topic/307877-samsung-rc720-strange-usb-issue/#findComment-2164933 Share on other sites More sharing options...
Resset Posted September 1, 2015 Author Share Posted September 1, 2015 I have USB 2.0 ports only. It is clean 10.10.5 installation from Mac App Store. I've only updated iTunes.
