drivers/usb/serial/bus.c:185:
warning: passing argument 1 of free_dynids from incompatible pointer type
Above build warning comes when CONFIG_HOTPLUG=n because argument of
free_dynids() in serial/bus.c is a struct usb_serial_driver, not a
struct usb_driver. This is not a runtime bug, because the function
is an empty stub and never dereferences the passed pointer anyway.

Two of the CDC ACM control requests in the serial gadget have never
been correct, and have been reported to cause serious troubles ... as
in, soft lockup and maybe watchdog reset (depending on hardware).
This patch makes those request fail cleanly, rather than misbehaving.
Someone using CDC ACM should fix them according to the FIXME comments
which now replace the previous bugs.

I would like have the attached patch added to Linux kernel. The three
usb flash memories listed in the patch are being used in Intel's
ClassmatePC and need USB_QUIRK_RESET_RESUME to work reliably when
resuming from ram.
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.
Typical kernel log showing the problem is:
usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6
This patch works around the device limitation by adding "Rockchip ROCK MP3"
to unusual USB devices list and limiting data transfers to 64 sectors (32kB)
per command.
Tested on 2.6.23-rc5 (amd64).

Recent versions of the Linux kernel auto-suspend attached USB devices.
After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints
don't seem to wake back up correctly, causing further use with libgphoto2
to fail with a -114 "OS error in camera communication" error.
A similar fix is probably necessary for this camera in PTP mode, which
identifies as USB product id 0x3102, but we haven't tested this.
As part of our testing process, we tried the USB_QUIRK_RESET_RESUME
quirk also, it's not helpful in this case.

This patch (as961) fixes a couple of bugs in the disconnect pathway of
usb-storage.
The first problem, which apparently has been around for a while
although nobody noticed it, shows up when an aborted command is still
pending when a disconnect occurs. The SCSI error-handler will
continue to wait in command_abort() until the us->notify completion is
signalled. Thus quiesce_and_remove_host() needs to signal it.
The second problem was introduced recently along with autosuspend
support. Since usb_stor_scan_thread() now calls
usb_autopm_put_interface() before exiting, we can't simply leave the
scanning thread running after a disconnect; we must wait until the
thread exits. This is solved by adding a new struct completion to the
private data structure. Fortuitously, it allows the removal of the
rather clunky mechanism used in the past to insure that all threads
have finished before the module is unloaded.

Some devices have a bug which causes them to send a 1-byte reply to
Get-Device-Status requests instead of 2 bytes as required by the
spec. This doesn't play well with autosuspend, since we look for a
valid status reply to make sure the device is still present when it
resumes. Without both bytes, we assume the device has been
disconnected.
Lack of the second byte shouldn't matter much, since the spec requires
it always to be equal to 0. Hence this patch (as959) causes
finish_port_resume() to accept a 1-byte reply as valid.

This patch contains two fixes submitted by Ondrej Palkovsky:
- the 'ACK' packet is sent after the transfer of the USB packet is
completed, i.e. in the write_callback function. Because the close
function sends the 'abort' command, a parameter is added that allows
the caller of garmin_write_bulk to specify, if the 'ack' should be
propagated to the serial link or dimissed.
This fixes the problem with gpsbabel, it has sent several packets that
were acknowledged before they were sent to the GPS and GpsBabel closed
the device - thus effectively cancelled all outstanding requests in the
queue.
- removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed
them into counters. It evades USB reset of the gps on every device close.
