Samsung Chromebook Plus, USB-C hub with passthrough charging. I am having trouble using wired mouse, keyboard with the Chromebook Plus. The devices will power on (non-functional) for a few seconds, and then turn off. This occurs when both charging and not charging with the passthrough.
I am not convinced the dock is defective because I’ve connected the USB3-HUB3ME through the USB-C hub and the Ethernet adapter works just fine. I can also read USB drives through the USB-C hub.
I was trying USB 2.0 drives originally. Though, good call! USB 2.0 seems to be the issue.
I had an old USB 2.0 hub ( http://plugable.com/products/usb2-2port/ ) laying around, so I gave it a shot as an intermediary. It worked! Both keyboard and mouse work at the same time when plugged into that, plugged into the USB-C hub w/ passthrough.
A little experimenting with what I have handy:
Thing, Plugable USB-C hub bare, Plugable USB 2.0 hub to Plugable USB-C hub
sandisk cruzer USB 2.0 SDCZ6-4096RB, Works, Works
USB2.0 MicroSD reader, Works, Works
AmazonBasics mouse, Broken, Works
USB keyboard, Broken, Works
Sandisk USB 3.0 drive SDCZ43-016G-G46, Broken(!), Works
Steam controller via wireless USB 2.0 dongle, Broken, Works (lizard mode; no mouse)
Steam controller via wired USB 2.0 cable, Broken, Works (lizard mode; use as mouse!)
Yubikey 4 Nano (new version), Broken, Works
Thanks for the info. Very strange, I’m not sure if I have an explanation for the behavior you are seeing. It could be a compatibility issue with the VIA VL100 chipset in our hub not being fully compatible with the USB-C implementation for your Chromebook Plus.
Ultimately we may need to offer you a return for a full refund as we don’t have the same system here for testing.
