[HTC U11  Questions & Answers] alz_uk:
use this usb c hub its the best by far, the only adapter to do 4k 60hz for gaming needs etc but only bad thing is its got usb 2.0 port instead of usb 3.0 which is a bottleneck for hi speed file transfer needs. but other than that it does everything you need it to do like act as a ultra low power 4k 60hz tv box, ultra low power 4k 60 hz gaming rig(emulators etc) and offcourse charging all at the same time via quick charge 3.0 thats 30 watts max. my setup consists of 2x usb gamepad, 4k 60hz hdmi tv with HDR, a 500GB external 2.5"inch hard drive. a usb keyboard and a wireless 2.4ghz mouse all with this adapter oh and another secondary usb 2.0 hub with power and sd card etc connected to the first hub.

you may have initial problems setting up all your devices and enabling enough power to power the phone and the devices so always use powered usb hubs so you dont create a situation where the battery drain is larger than the power being provided. i had to fiddle around to find the sweet spot. for example i realised there are different scenarios when connecting the devices to usb type c hubs. some for example this one im using from scan needs the power charger to be connected the last after connecting hmdi and usb if not done last the power provided is much less or the drain is much higher. when you connect the power leade to the adapter the hdmi display gets cut out and you have to then reconnect the hdmi display to re enable it. i have tested a few of these usb type c hubs with hdmi etc they all seems to have this problem they wont all (display, charge, usb) work when connected at the same time for example connect the devices and display and charge to the hub then connect the hub to the phone, you have to re insert it into the hub after disconnecting it to enable it.

after fiddling around with different combinations for a few days now i have finally been successfull with having a usb external hard drive, hdmi 4k 60hz display and a keyboard and mouse and phone having enough charge to stay on green led while i do everything such as web browse, play games, watch 4k and use keyboard and mouse on my htc u11.

ive noticed when i was using a standard cheap usb optical mouse those with flashing lit leds on all the time caused my charging power to drop so after changing the mouse for a optical 2.4ghz usb mouse it seems to have increased the power for charging which nipped it in the bud for me and my setup. now my htc u11's charge led stays green all the time.

further from my experiments i realised some methods of connecting caused quick charge 3.0 to work but as soon as it reached 100% charge the charge power would drop so slow battery drain would start to happen while other scenarios reduced this battery charge drop rate and was slower in draining. heres another scenario when i plugged everything the display the charger and the usb external hard drive to the scan club 3d dock the hard drive wouldnt work at first then i realised my external hdd was formatted ntfs since it allows large file sizes for 4k movies. then i had to format the external hdd as exfat since ntfs is not recognised in android only fat 32 and exfat. fat 32 dosent allow file sizes above 4gb while exfat and nts do so exfat was the best option for formatting my external hdd since it was recognised by wndows and android. second problem factor i had was that not all secondary hubs would work. i first tried a usb 3.0 4 x port hub (not extrenally powered) and a cheap 4 x port usb 2.0 hub but they wouldnt work with my external usb 3.0 hdd the drive would appear in file explorer but wouldnt show its contents. so then i finally got a usb 2.0 hub with sd card and external power and 3 x usb 2.0 ports and that worked!!! so when connecting a secondary usb hub its most likely needs to be externally powered.

with the new usb type c 3.1 port comes lots of bugs that need to be hammered out on the software firmware level before its all totally plug and play. my htc and the scan club 3d hub didnt work too well at first but after a few htc u11 firmware updates things were alot smoother.
