Clarify usb_powered() and fix some code.

2015-01-08T15:45:32+00:00

Either by mistake or because its meaning changed, usb_powered() doesn't mean
what the name suggest, so clarify its meaning by renaming it to usb_powered_only.
So use of usb_powered() are replaced by usb_inserted() when it makes more sense.

usb: add support for hardware handled SET ADDR/CONFIG

2012-12-07T12:37:26+00:00

Some USB controllers like the one of the Rockchip 27xx handle some
requests in pure hardware. This is especially a problem for two
of them:
- SET ADDR which is used by our core to track the DEFAULT/ADDRESS
  state and is required for the drivers to work properly
- SET CONFIG which is used by our core to initialise the drivers
  by calling init_connection()
In these cases we need a way to notify the core that such requests
happened.
We do this by exporting two functions which directly notify the
core about these requests and perform the necessary init steps
required without doing the actual USB transfers. Special care is
needed because these functions could be called from an interrupt
handler. For this reason we still use the usb_queue and introduce
new IDs so that they are processed in order and safely.

No functional change is intended, both in the usbstack and on
targets without such quirks.

Reorganise USB initialisation to not depend on a specific enumeration sequence, by Bartosz Fabianowski, with minor tweaks by Michael Sevakis (FS#12497)

2012-01-04T21:55:09+00:00

FreeBSD apparently sends a SET_ADDRESS first, which confused our code.
This patch fixes that, and also simplifies the connection handling a bit.

Simplify and neaten-up usb.c a bit. USB_INSERTED and USB_EXTRACTED are always used as events to indicate cable state. USB_HOSTED is posted to indicated that a host was detected.
