From: Chris Chiu <chris.chiu@xxxxxxxxxxxxx> There will be crazy numbers of interrupts triggered by 8188cu and 8192cu module, around 8000~10000 interrupts per second, on the usb host controller. Compare with the vendor driver source code, it's mapping to the configuration CONFIG_USB_INTERRUPT_IN_PIPE and it is disabled by default. Since the interrupt transfer is neither used for TX/RX nor H2C commands. Disable it to avoid the confusing interrupts for the 8188cu and 8192cu module which I only have for verification.
