One monitor was back - but only briefly, unfortunately. I also tried reinstalling the DisplayLink drivers. I then tried unplugging everything from the docking station and replugging it: power cable first > then USB-C host cable > then HDMI cables but it didn’t work. I tried unplugging it again, and the other one, which ended with me not having none external monitor working at all. I tried unplugging the HDMI and replugging it but that didn’t solve the problem. Suddenly, the first monitor wasn’t able to connect when I plugged in my laptop. I have a HP Spectre Notebook (Win10) and used to connect 2 external moniors (also HP) via HDMI to the docking station (UD-ULTCDL) to have 3 displays in total without any problems.Įverything worked just fine until this morning. Mostly those are the only ones that can use USB slave devices and charge.įew BT keyboards are as good as a USB slave.All of a sudden, I’m having troubles connecting my monitors to my plugable USB-C docking station. There is no point to a hub.Īny OUT port on a hub can charge the tablet, but it is then in slave mode and can't connect to the OUT port with a USB keyboard.Ī few current tablets (not eink) do have a separate coax socket for power. Similarly you can charge the BT Keyboard from a separate charger or a dual outlet charger. If it's properly designed it won't do it any harm. You can simply uses a BT keyboard and have the ink tablet on the charger. Neither the in port of a hub, nor the splitter cable will power the phone or tablet. The other is simply powering a slave device from your charger to save the tablet battery, which a powered hub can also do. One only works with the special hardware of phone or tablet.
I have two special power splitter cables. It's a non-standard hardware design on some phones and tablets. Most only charge (take external power AT ALL) when in slave mode, to a charger or a USB host port. Very very few tablets or phones can charge from the USB socket when it's in USB2Go host mode connecting to a hub, keyboard or anything.
