ACASIS 10-in-1 USB C Hub Q&A
ACASIS Tutorials
Q: Why my ACASIS cannot be recognized and it doesn't work?
A: Please make sure that your computer is connected to the "PC" port of the hub as the below red arrow shows, instead of “PD 100W” or any other USB C, USB A ports on the hub. If your computer only has USB Type-A port, you need to use a USB A to USB C data cable (the HDMI function will be unavailable).

Q: Why my SSD cannot be recognized?

A: If a high-power consumption device is connected to the hub, like a large capacity SSD (1T or bigger, depending on the computer performance), please plug a power adapter(at least 60W, it's the best to use your original device charger) into "PD" port.

If you are using a laptop or iPad, please connect the PD charger of your device to the hub, then you can charge your laptop or iPad while using the hub.



If you cannot recognize SSD even if you plug the right ports as above and other functions work normally, PLEASE RECHECK IF THE SSD IS FULLY INSERTED INTO THE SLOT!!!



Q: Why does my ACASIS read/write SSD at 30-50Mb/s speed?

A: Please make sure you connect the device with the cable sent with Acasis hub or better (like a real USB3.0/3.1/3.2 cable or Thunderbolt 3 certified cable). If you use a cable that only support charging, the speed will be much slower than normal.



Q: Why does my ACASIS become hot while running?

A: Whten you are using SSD for data transferring(especially NVME, which temperature can be up to 70) or multiple ports working at the same time, it will generate a lot of heat.

This compacted hub itself is designed as a heat sink. The thermal pad (the white strip in the package) will connects the SSD with the aluminum hub to dissipate the heat.


Q: What is the white foam strip? How to install it?

A: It is the thermal pad, which will help heat dissipation.

Remove both sides'films first then stick to the SSD surface, and this pad is removable without residue. 




Q: Why my SD card can not be recognized?

A: ①Please insert the card in a right direction.

②Please make sure your sd cards' file system can be recognized by your computer.

Mac OS: ExFAT, FAT or MacOS Extended

Windows: NTFS, ExFAT

Q: Whta if I don't want the sound output through my ACASIS?


▶ Windows OS


If you're connecting to an audio device—such as headphones or speakers—using USB or HDMI, you might need to set that device as the default audio device.

If you're using an external monitor that doesn't have built-in speakers, make sure that the monitor isn't already selected as your default output device.

If it is, you won't have any audio. You can check that when you set your default output audio device. Here's how:

1.In the search box on the taskbar, type Control Panel, the select it from the results.

2.Select Hardware and Sound form the Control Panel, and then select Sound.

3.On the Playback tab, right-click the listing for your audio device, select Set as Default Device, and then select OK.
