In my quest to try and figure out why test 14 (control write) doesn't
work with my EZ-USB board, I noticed that sometimes testusb reported
no error even though the kernel log complained "byte 0 is 0 not 2" etc.

This is a new driver for the Cypress CY7C63xxx mirco controller series.
It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus
GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I
ported to kernel 2.6 using sysfs. I intend to support more controllers
of this family (and more features) as soon as I get hold of the required
IDs etc. Please see the source code's header for more information.

This patch (as693b) makes the usbtest driver report errors in the
isochronous bulk transfer tests instead of always returning 0. As an
arbitrary cutoff, an error is returned if more than 10% of the packet
transfers fail. It also stops a test immediately upon receiving an URB
submission error.
For a test harness, it's especially important to report when errors occur!

ctrl_complete functions acquires ctx->lock and tries to unlink
all queued urbs in case of errors through usb_unlink_urb func.
In its turn usb_unlink_urb calls, through the hcd driver,
usb_hcd_giveback_urb which calls ctrl_complete again. At this
time, ctx->lock is already taken by the same function.

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time. The bug is seen as a hung USB box and the kernel error:
drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110
The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued. This affects only device startup.

Previously, scatterlist tests didn't write patterned data. Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage. Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.
This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets. It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.
Note this patch doesn't add checking for correct data patterns on the way
IN from peripherals, just a FIXME for later.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

This updates the handling of power state for USB interfaces.
- Formalizes an existing invariant: interface "power state" is a boolean:
ON when I/O is allowed, and FREEZE otherwise. It does so by defining
some inlined helpers, then using them.
- Adds a useful invariant: the only interfaces marked active are those
bound to non-suspended drivers. Later patches build on this invariant.
- Simplifies the interface driver API (and removes some error paths) by
removing the requirement that they record power state changes during
suspend and resume callbacks. Now usbcore does that.
A few drivers were simplified to address that last change.

and restore asynchronously.

here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.
Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
about the graphics internals.
Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.
Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.
Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.
Heavily tested, as usual. Please apply.
One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.

29 July 2005, Cambridge, MA:
This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK
flag from the Linux kernel. Mr. Stern explained, "This flag is a relic
from an earlier, less-well-designed system. For over a year it hasn't
been used for anything other than printing warning messages."
An anonymous spokesman for the Linux kernel development community
commented, "This is exactly the sort of thing we see happening all the
time. As the kernel evolves, support for old techniques and old code can
be jettisoned and replaced by newer, better approaches. Proprietary
operating systems do not have the freedom or flexibility to change so
quickly."
Mr. Stern, a staff member at Harvard University's Rowland Institute who
works on Linux only as a hobby, noted that the patch (labelled as548) did
not update two files, keyspan.c and option.c, in the USB drivers' "serial"
subdirectory. "Those files need more extensive changes," he remarked.
"They examine the status field of several URBs at times when they're not
supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag
is removed."
Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all
of Linux's USB drivers, did not respond to our inquiries or return our
calls. His only comment was "Applied, thanks."

The following driver provides complete interrupt-in and interrupt-out
reports (raw data) to a user program. Until now it uses the
HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it
will be ok for you - and I will be happy, if you assign 8 minor numbers.
I have tested it in several environments and it works very well for me.
However, it has a problem with two or more devices at the same hub, if
the two or more devices need 1 ms interrupt-in transfers. Unfortunately
more than one interrupt-in transfer every ms isn't possible (ehci
driver?). This is why the min_interrupt_in_interval and
min_interrupt_out_interval are increased to 2 ms (see the corresponding
module parameters). This way, I can use two devices simultaneously at
the same hub.
