e0ba240008 Numerous fixes brought in by Lennart Augustsson from NetBSD:
- Request the maximum number of LUNs on a device if it is
  a Bulk-Only device.

- Handle NO_TEST_UNIT_READY case for SCSI

- Add NO_START_STOP quirk for LS-120

- Fix a KASSERT which was the wrong way around.

- Kickstart the LS-120 with the infamous LS-120 specific command of
  which no one knows what it doesn, apart from the fact that it appeared
  in the Linux code someday.

d1a0c5a2fa OpenBSD has a broken debugger that does not grok static. Use a
#define Static  static

that the OpenBSD folks can define it to be empty if they like.

bb27208af1 Add a hack to cam that makes the cam_xpt available to the rest of the
kernel. Justin agress that there is no other reasonable alternative to
do automatic rescans on connect.

The problem is that when a new device attaches to a SIM (SCSI host
controller) we need to send a XPT_SCAN_BUS command to the SIM using
xpt_action. This requires however that there is a peripheral available
to take the command (otherwise xpt_done and later bomb). The RESCAN
ioctl uses the same periph.

This enables a USB mass storage drive to do an automatic rescan on
connection of the drive.

The automatic dropping of a CAM entry on disconnection was already
working (asynchronous event).

The next thing to do is find someone to commit a change to vpo to do the
same thing. Just port umass_cam_rescan and friends across to that
driver.

c47752f2d5 Shoot. Did a compile in the wrong directory and missed this compiler
error.

Could someone pass me the pointy hat, please?

e11b908ab2 Remove a static variable, a uniquifier for a SCSI command. It might have
produced inadvertently failed transfers in the case were multiple
Bulk-Only devices are connected and a command is prepared at the same
time.

1d9f7bb597 I got the CAM numbers (path id's, buses, unit numbers) and newbus
unit numbers all wrong. This did not show up because most of them where
zero anyway.

Use a separate buffer for command transforms instead of fiddling with
the existing cdb_bytes.

Take CAM_CDB_POINTER into account. Nobody is using it, but someone might
in the future.

Be more picky about what to accept in the UFI command set.

First attempt at implementing the ATAPI command protocol transforms.
This should at least make Imation Superdisk and other e-Shuttle based
devices show as attached. Maybe they even work to some extent.

b9cb6f83fc Revert to a static value for the timeout. The timeout was supposedly
to be based on the transfer speed, but I got it all wrong. The by far
biggest factor in the timeout is the start of a removable device, which
is about 2 seconds anyway.

5d7a27cc6e The REQUEST SENSE command is 6b not 16b. Use the struct scsi_sense to
indicate that we are working with that command.

750285f9d3 The completely rewritten USB Mass Storage driver. It supports the following
devices:

Tested:
   Zip 100 USB drive
   Y-E Data USB floppy drive

Untested: (let me know whether or not it works!)
   TEAC USB floppy drive
   Zip 250 USB drive

b4c5ebb3f4 Update de driver for the request->xfer changes.
Add a remark about how the system will panic after you've unplugged the
drive.

aeb2d2626b Synchronisation with NetBSD as of 1999/11/16:
Cleaning up the code:
- Declare many functions static
- Change variable names to make them more self explanatory
- Change usbd_request_handle -> usbd_xfer_handle
- Syntactical changes
- Remove some unused code
- Other KNF changes

Interrupt context handling
- Change delay to usbd_delay_ms were possible (takes polling mode into
  account)
- Change detection mechanism for interrupt context

Add support for pre-allocation DMA-able memory by device driver

Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).

usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.

usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
  come and go.

ohci.c
- Handle the case when a USB transfer is so long that it crosses two
  page (4K) boundaries.  OHCI cannot do that with a single TD so we make
  a chain.

ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer.  This makes the driver slightly more
  efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
  causes printing to fail sometimes.

usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
  and if not, complain.

usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
  the driver or the usbdi layer.

b6c58860ab Major synchronisation with the NetBSD USB stack:
- Some cleanup and improvements in the uhci and ohci drivers
- Support for plugging and unplugging devices improved
- Now available is bulk transport over OHCI controllers
- Resume and suspend have been temporarily been disabled again.  Proper
  support for it is available in the uhci.c and ohci.c files but I have
  not yet spent the brain cycles to use it.
- OpenBSD now uses the USB stack as well
- Add FreeBSD tags

1c9d24db05 1) Do not include usbdivar.h and access the interface descriptor through
usbd_get_interface_descriptor
2) remove soft reset. It's been dropped from the USB Mass Storage Bulk-Only
   Specification
3) move the clear feature halt to the reset routine.
