I use VirtualHere USB Server on my Raspberry to wirelessly connect my 3D printer in my garage to my computer.
And sometimes, while printing, the connection stops for a second so it completely crashes my print.
I don't really have any other information.
Please help me !
P.S: Sorry for my bad english.
It is connected over wifi or lan?
Anyway try this on your pi
sudo apt-get update;sudo apt-get upgrade -y;sudo rpi-update;sync;sudo reboot
and try again.
