El Capitan shutting off USB power on MacBook Pro?
Since upgrading my Early 2015 13" Retina MacBook Pro to El Capitan from Yosemite, I have noticed that it shuts off power to the USB ports when it's asleep. I know for 100% certain it didn't use to do this, as I travel constantly for work and use my MBP as a convenient charging hub in hotels. Plug everything in, go to sleep, wake up and everything is ready for the day's meetings/flights.
Since updating on Wednesday, this isn't happening. I'll plug all my devices in and they will get a little top-up, but in the morning the MBP is fully charged and my Watch/iPhone/iPad/whatever are run completely down instead of fully charged.
I have already done an SMC reset. Anyone else seeing this or have any suggestions?
MacBook Pro with Retina display, OS X El Capitan (10.11)
