Description (partial)

while running install operations like install verify packages, install operations failed on taiko LCs due to USB hang issue on taiko card

USB driver unable to receive interrupts from EHCI controller. It seems the driver misses the interrupt and hence failed to 
ack the controller by clearing the status register.
