The net2280 driver is too eager to send zero-length packets when
IN tokens are received on ep0. No such packet should be sent (the
driver should NAK) before the gadget driver has queued the proper
response. Otherwise deferred responses are impossible.
This patch (as823) makes net2280 avoid sending ZLPs for IN transfers
on ep0 until a response has been submitted, and avoids stalling when an
OUT packet is received before a request has been submitted for an OUT
transfer on ep0.

The mass storage device from Digitech designed for Flash Cards, as found
on (for example) the GNX4 device has issues with residue, similar to the
bug report at http://kerneltrap.org/node/6297. This patch adds the
faulty storage device to unusual_devs.h, this not only reduces the noise
in dmesg but also increases the transfer speeds by a factor of 7x for me
(89kB/s -> 637kB/s).

Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.

All the other root-hub suspend or resume log messages, in ohci-hcd or

Allright. As Greg KH suggested I split this big patch into smaller ones to
make the changes easier to review. Having no better idea how to split that I
split it on a 'patch per file' basis. All those patches clean redundant 'if' before
usb_unlink/free/kill_urb():
if (urb)
usb_free_urb(urb); /* unlink / free / kill */
I decided not to touch bigger 'if's like
if (urb) {
usb_kill_urb(urb);
usb_free_urb(urb);
urb = NULL;
}
as that would be probably too intrusive. One of patches also fixes
drivers/usb/misc/auerswald.c memleak I found when digging the code. All those
patches are against 2.6.19-rc4.

Several functions in USB core overlap with global functions.
The linker appears to do the right thing, but it is bad practice and makes
debugging harder.

This patch (as809b) moves the declaration of the hub driver's private

This patch (as814) adds usb_autopm_set_interface() to the autosuspend
API. It also provides convenient wrapper routines,
usb_autopm_enable() and usb_autopm_disable(), for drivers that want
to specify directly whether autosuspend should be allowed.

This patch (as813) gathers together common code for USB interface
autosuspend/autoresume.
It also adds some simple checking at the time an autosuspend request
is made, to see whether the request will fail. This way we don't
add a workqueue entry when it would end up doing nothing.

We have no benefits of having the usb_endpoint_* functions as functions,
but making them inline saves text and data segment sizes:
text data bss dec hex filename
14893634 3108770 1108840 19111244 1239d4c vmlinux.func
14893185 3108566 1108840 19110591 1239abf vmlinux.inline
This is the result of a 2.6.19-rc3 kernel compiled with GCC 4.1.1 without
CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set.
USB support is fully enabled (while most of the other drivers are not),
and that kernel has most of the USB code ported to use the endpoint
functions.
That happens because a call to those functions are expensive (in terms
of bytes), while the function's size is smaller or have the same 'size' of
the call.
