usb: increase timeout on the control endpoint
Some USB keys are very slow at answering the initial GET_DESCRIPTOR or
SET_ADDRESS request.
I have encountered a couple of USB keys which take respectively 140ms
and 230ms to send back their data packet on such a request, and thus
fail with the current code.
According to the USB2.0 standard 9.2.6.4, the device should answer the
standard device requests (e.g. GET_DESCRIPTOR or SET_ADDRESS) in less
than 500ms, so let's increase the control endpoint timeout to that
value.
