I'm using thishttp://www.amazon.co.uk/EasyAcc-Bus-Pow ... B00PF9AB1O
I've got PCI mode and vbus on in bios.
Currently have a hard drive, Logitech dongle thing and Xbox pad plugged in working perfectly. it's nice and neat too.
Running relatively intensive processes can see charge slowly drain, so I'll try a 3amp plug soon.
Cheers for the bios tip OP!
I used to have it working as well, but after few months of not using Linx (well, it is useless hardware), it no longer works, it is only data or charge.
Same with Dell Venue 8 cable
It ONLY works while booted to full OS (Windows with loaded drivers). It does NOT work in BIOS or in basic WinPE!
