USB disconnects briefly when I turn on the light switch?
Hello,
I have a 3D printer here that is connected to the PC via USB.
There is a light switch near the printer
Every time I press this button, the USB connection to the printer is disconnected briefly, but everything stays on and the light also goes on/off normally
Does anyone know what could be causing this?
There is EMC protection on the printer or on the lamp inadequate. Electrical appliances from the Asian (favorable) market without CE markings can interfere with each other. These disturbances spread over the power lines and sockets (networks) of the connected devices.
A USB cable that is too long or not properly shielded can also cause this situation.
My suggestions are:
Good luck!
Moin Moin,
Thanks for the detailed answer!
Founded yesterday that the USB cable is very badly shielded, so it was right
Be sure to exchange this, thank you for the tips

Had a similar behavior in my apartment. There were slim LED lamps that, although well lit, radiate EM stretch. Even the TV didn’t go when the light burned. After a change of lamps, the haunt was over.
