USB: ehci-dbgp: errata for EHCI debug controller initialization
On some EHCI usb debug controllers, the EHCI debug device will fail to
be seen after a port reset, after a warm reset. Two options exist to
get the device to initialize correctly.
Option 1 is to unplug and plug in the device.
Option 2 is to use the EHCI port test to get the usb debug device to
start talking again. At that point the debug controller port reset
will succeed.
