I reviewed Vorke Z3 Android mini PC last month, the first mini PC I’ve received with a USB type C port capable of handling video output too. I could see support for dual HDMI displays in the firmware, but at the time I did not have a USB type C hub with HDMI output. But Dodocool sent me their DC30C USB type C hub so I’ve finally been able to give a try.
- USB Input – 13 cm USB 3.1 Type-C cable
- USB Outputs – 3x USB 3.0 type A ports up to 5 Gbps; 1x USB 3.1 Type-C PD charging port
- Video Output – HDMI port
- Storage – SD & Micro SD card reader
First the package which gives basic info about the USB hub.
One side comes with the SD and micro SD card slots with LED indicator, and two USB 3.0 ports…
I found a two USB flash drives, and a SD card that I connected to the USB hub, as well as an HDMI cable connect to a Full HD TV, and my phone’s charger.
At first I did not connect the USB type C charger, and the storage devices would not show, and while my Full HD TV would detect something was connected via HDMI, it would show “No Signal”. I tried to connect the HDMI cable from the USB hub to the 4K TV, and I had the same problem. So I connected the USB power supply, and I could see the power draw from Vorke Z3 drop by about 2 Watts, but I would still not be able to use anything connected to the USB hub. Later I tried to disconnect and reconnect the USB hub, and magically everything worked (almost) as expected. It looks like disconnecting the USB type C port supply and reconnecting it may have an effect too.
We have the 4K TV on the left connected directly via Vorke Z3’s HDMI port, and the Full HD TV on the right connected via the USB type C port through DC30S’s HDMI port. The option “Display different content for double screen” did not work for me, so I could just use it to mirror the display, but that’s related to Vorke Z3’s firmware, not Dodocool’s USB hub.
Storage also worked fine, but all USB flash drive were boot drives, and not recognized the TV box, I had another random USB flash drive, and I could mount and navigate LIBREELEC partition, as well as copy files to it.
