One customer has a USB hub with about 5 USB sockets plugged in. The one Hub output socket goes to PC into a USB port the other PC Base USB has a USB Mouse connected.
Anyway many thinkgs cause PC to lock up. My guess is contention.
Checked DeviceManager
Mouse has THREE

HID Compliant mouse

USB has THREE
General purpose USB Hub
Intel 82371AB PCI to USB Universal Host Controller

Never encountered these Hubs, but three on each seems excessive.
Is this normal
