Hi Since the implementation of hw test support is mandantory for usb ehci controllers i'd like to know if there is a common infrastructure within the kernel for hw tests? The only thing i found was this rather old patch http://ns3.spinics.net/lists/linux-usb-devel/msg06366.html And the musb driver which presumably uses the debugfs to enable testing functionality? Which would be the right way to tackle this? I would like to implement this functionality especially in the ehci-mxc driver.
