First, I use Debugging Tools for Windows
Second, the bugcheck points to the driver
, not hardware:
USB Driver bugcheck, first parameter is USB bugcheck code.
Arg1: 0000000000000008, USBBUGCODE_RESERVED_USBHUB
Arg2: 0000000000000006, USBHUB_TRAP_FATAL_TIMEOUT
Arg3: 0000000000000005, TimeoutCode: Timeout_PCE_Suspend_Action3 - PortData->PortSuspendEvent
Arg4: fffffa80050c9b20, TimeoutContext - PortData
All your dmps with the possible exception of one had the same bugcheck and Probably Caused By line, which sounds like it really is the USB driver.
As for the chipset update, go for it. At the worst, it won't help with your problem.
As for the webcam, try uninstalling your USB drivers
in Device Manager, and reboot. See if that helps.
