usb port

Recently added a 7 port usb. When run shredder, computer makes a crackling
sound. Also, the mouse and keyboard are connected to usb port and the mouse
is freezing on a regular basis since hooking up. Port is 2.0 high speed,
but computer is an older Dell desktop. What is causing problem with mouse??

If the PC produces crackling sound then the USB hub/wiring
is acting like an antenna and transferring the RF generated by the
shredder to the speakers/sound card.

A mouse & keyboard is a high priority peripheral. A Seven port
hub is still limited by the on-board USB 2.0 controller/hub's total
bandwidth and power constraints that serves the expansion hub.

A better solution is a PCI based USB card. It will have it's own
dedicated controller/hubs and not be limited like your current setup.
