      [PATCH] USB storage: Remove unneeded scatter-gather operations in sddr09 · a01e2e63
      Alan Stern authored
      This patch removes some unnecessary scatter-gather code from the sddr09
      driver.  In its place a single smaller buffer is re-used each time through
      an I/O loop, as opposed to transferring all the data at once.
      
      Andries Brouwer kindly tested this and suggested some improvements to get
      it working right.

      [PATCH] USB scanner driver: new device ids · 422cbad1
      Henning Meier-Geinitz authored
      Added vendor/product ids for Epson, Genius, Microtek, Plustek,
      Reflecta, and Visioneer scanners. Removed ids for HP PSC devices as
      these are supported by the hpoj userspace driver.

      [PATCH] USB: Fix khubd synchronization · 94ef3b63
      Alan Stern authored
      It improves synchronization with hub_irq() and guarantees that the hub
      disconnect() routine doesn't exit until the URB's completion routine has
      finished.

      [PATCH] USB: khubd optimization · 74636bf5
      Alan Stern authored
      It changes spin_lock_save() to spin_lock() within the completion routine
      and list_del()/INIT_LIST_HEAD() to list_del_init().  It's nothing more
      than a minor optimization.

      [PATCH] USB: ohci, fix iso "bad entry" bug + misc · ed63f425
      David Brownell authored
      A while back there were some reports of ohci reporting a "bad entry"
      diagnostic, mostly with ISO transfers, which were mysterious until
      I recently found an easy way to reproduce it.
      
      This patch:
      
        - Fixes at least one cause of that "bad entry" diagnostic by
          waiting for INTR_WDH before completing ED unlink processing.
          (Else URB unlinking could free TDs on the donelist, so the
          WDH processing would see those entries as "bad".)
      
        - Merges the patch from Darwin Rambo <drambo@broadcom.com>,
          coping with CPUs that can't do 16 bit accesses (MIPS).
      
        - Renames a function as start_ed_unlink(), matching its role.
      
        - Fixes minor debug output issues, including a FIXME to tell
          more info about TDs on the periodic schedule.  And adding
          some missing newlines (makes this patch seem big).
      
      Nobody's complained much about that "bad entry" issue lately, but
      if necessary that part would be particularly easy to split out.
      
      Please merge to the next kernel that gets USB patches.

      [PATCH] USB storage: Fix logic error in raw_bulk.c:us_copy_to_sgbuf() · 1fca60c0
      Alan Stern authored
      This patch fixes a simple logic error in the routine that copies data from
      a driver buffer to a scatter-gather user buffer.

      [PATCH] USB storage: Issue CBI clear_halt and fix BBB residue · af62566f
      Alan Stern authored
      This patch does 2 things (bad, I know -- but they're both pretty small
      and pretty obscure).
      
      The CBI specification states in section 2.4.3.1.3 that
      
      	... the host shall also issue Clear Feature for Endpoint Halt
      	to the Bulk In pipe if the device reports that the Data In
      	command block has Failed.
      
      along with a note in section 2.5.3 that Data Out commands should work
      analogously.  This patch does that, along with cleaning up the status
      detection logic a little.
      
      For Bulk-only transfers we currently ignore the dResidue field in the CSW,
      except for reporting it (without byte-swapping!) in a debug message.  The
      patch uses it to compute the residue value returned to the SCSI layer.
      Note that the Bulk-only spec allows devices to transfer more data than
      they actually use (i.e., they may add padding or ignore stuff) and then
      inform the host of this by means of the dResidue value.  The logic used is
      simple: our reported residue is the larger of what the device claims and
      what we didn't transfer, except that it can't be larger than the total
      transfer length.

      [PATCH] USB storage: Command failure codes for sddr09 driver · 78dd3042
      Alan Stern authored
      This patch updates the sdd09 subdriver to make it return Command Failure
      with appropriate sense data (rather than Tranport Error) when:
      
      	a MODE-SENSE command requests an unsupported page;
      
      	a CDB includes an unrecognized command code.
      
      This should help prevent confusion and excessive retrying by the SCSI
      drivers.

      [PATCH] USB: fix comment in usblp · d0d2d872
      Pete Zaitcev authored
      I know Linus is not taking cleanups at this point, but perhaps
      you can delete it in your tree. Seems like someone (Oliver?)
      fixed all the garbage in old printer.c, so the comment is not
      needed anymore.
      
      I reviewed changes, and usblp.c looks correct. I'm doing backport
      to 2.4 for Fedora right now.

      [PATCH] USB: change cdc-acm to do RX URB processing in a tasklet · 65dacb23
      David Brownell authored
      Just for cdc-acm, it pushes RX URB processing into a tasklet;
      and has minor cleanups.
      
      I cc'd Vojtech since he's this driver's maintainer.  If this
      checks out, usb-serial will need similar changes.
      
      
      p.s. the issue is a WARN_ON that tells us:

      [PATCH] Lastminute IEEE-1394 fixes · 9b67c27b
      Ben Collins authored
      I've got a lot more changes than what's included here.  I've put this
      down to the bear minimum to get things working sanely.
      
      Mainly, I just want to get all the people hit by this a chance to use
      2.6.0 without having to get our tree. Changes itemized:
      
       - Fix deadlock possibility in csr.c:read_maps()
       - Fix kmalloc to use ATOMIC in highlevel.c.
       - s/in_interrupt/irqs_disabled/ in ieee1394_transactions.c to fix
         warnings when transactions occured.
       - Introduce a release callback for the host driver and use it correctly.
       - Reorganize the nodemgr probe so we do an initial scan to discover
         devices, check IRM/CycleMaster, then do a final full probe when things
         are kosher. Fixes a problem where device registration and hotplug
         would cause some serious problems when a bus reset was forced in the
         middle of the probe.
