Basically, it is more stable to connect directly to the USB port of the PC.
(If the power supply of the PC is vulnerable, the self-powered HUB may be stable.) ）
There are a few things to keep in mind when using HUB.
１．Please use USB3.0 HUB.
If you use the USB 2.0 type, it basically does not work.
However, if you adjust the number of clocks on the camera side, the image may be displayed.
However, the speed is extremely slow, and the low-resolution camera is reflected, but the high-resolution camera is
Abnormal operation such as not being displayed may occur.
２．Please use the self-powered HUB as much as possible.
Especially if you are using a notebook PC, using USB bus power will increase the supply current to the camera.
It may be insufficient and show abnormal behavior.
Of course, it depends on the capacity of the power supply on the PC side, so it may work without problems.
(supplement)
Even if you choose a USB 3.0, self-powered HUB, the communication speed of USB 3.0 may be limited.
There are some HUBs that are not listed.
(Depending on the HUB, communication speed may decrease.)
In this case, the low resolution (low amount of data) camera will work, but
High-resolution camera (large amount of data) Abnormal operation such as camera not moving occurs
There may be cases.
