[cdi-devel] [PATCH v4 0/4] USB support

[Max Reitz <max@xxxxxxxxxx>]

The changes from v3 to v4 have not been tested, because it's more fun
this way.


v4:
- Less patches, because some have already been applied
- Patch 1:
  - Added cdi_usb_device_osdep
  - Added start_transaction() to cdi_usb_hcd
- Patch 2:
  - Replace fprintf(stderr, ...) by printf(...)
  - Rename retire_qtd() to retire_first_qtd() and take a QH instead of a
    qTD
  - Never call enter_qh() on QH that may currently be processed by the
    HC
  - Subsequently, do not call enter_async_qh() from
    ehci_create_transaction() (invoked by ehci_enqueue())
  - Implement ehci_start_transaction()
- Patch 3:
  - Replace fprintf(stderr, ...) by printf(...)
  - Call start_transaction() where necessary
  - Never try to assign addresses greater than 127 (fail instead)
  - Fix calloc() call
  - Explain why there are two reset calls in new_hub()
  - Clean up the USB hub driver by pulling out functions like
    SetPortFeature() (as hub_set_port_feature())
- Patch 4:
  - Copy cdi_usb_device instead of keeping the reference
  - Fix the bulk_in vs. bulk_out stuff
  - Use integers for the device names instead of characters (e.g. "msd0"
    instead of "msda")
