This patch adds a second linksys vendor-id (077b) and the product id of the
pegasus based adapter USBVPN1
http://www1.linksys.com/Products/product.asp?prid=3D543&scid=3D30
Furthermore it replaces all LINKSYS_GPIO_RESET with DEFAULT_GPIO_RESET as both
are declared like this:
#define DEFAULT_GPIO_RESET 0x24
#define LINKSYS_GPIO_RESET 0x24
This is misleading and confusing.
The check is now done via the VENDOR_ID in pegasus.c:
if (usb_dev_id[pegasus->dev_index].vendor == VENDOR_LINKSYS

This patch (as628c) adds error handling to the USB HID core. When an
error is reported for an interrupt URB, the driver will do delayed
retries, at increasing intervals, for up to one second. If that doesn't
work, it will try to reset the device. Testing by users has shown that
both the retries and the resets end up getting used.

This makes OHCI use the driver model wakeup control bits for its root hub
(e.g. disable on amd756, because of chip erratum) and for the controller
itself. It no longer uses the hcd glue bits with those roles, and depends
on the previous patch making the root hub available earlier.
Note that on most platforms (boot code properly setting the RWC bit) this
gives a partial workaround for the way PCI isn't currently flagging devices
that support PME# signals. (Because of odd PCI init sequencing on PPC.)
That's because many OHCI controllers support "legacy PCI PM" ... without
involving any PCI PM capability.
USB wakeup from STR, if it works on your system, may still involve
tweaking things by hand in /proc/acpi/wakeup.

Make the HCD initialization sequence more sane ... notably, setting up
root hubs before HCDs are asked to do their one-time init. Among other
things, that lets the HCDs do custom root hub init along with all the
other one-time initialization done in the (now misnamed) reset() method.
This also copies the controller wakeup flags into the root hub; it's
done a bit later than would be ideal, but that'll be necessary until
the PCI code initializes them correctly. (The PCI patch breaks on PPC
due to how it sequences PCI initialization.)

This adds declarations for three USB peripheral controllers:
- Two high speed USB cores that can be licensed from Mentor Graphics
to be integrated into silicon:
* "musbhsfc" is for peripherals only, as found in for example the
IBM/AMCC 44EP processors.
* "musbhdrc" is OTG-capable (dual role), and is found in various
products including OMAP 2430 and the new DaVinci SOCs.
The "musbh" standing for "Mentor USB Highspeed", the rest standing
for "Function Controller" or "Dual Role Controller" (OTG-capable).
- The full speed controller on the FreeScale MPC8272.
Adding these definitions just allows gadget driver code to handle any
controller-specific logic; controller drivers are quite separate.

This patch modifies the behavior of the EHCI driver in an unlink path
that seems to be causing various issues on some systems. Those problems
have included issues with disconnection, driver unbinding, and similar
cases where urb unlinking would just not work right.
This patch should help avoid those problems by not turning off the async
(control/bulk) schedule until it's not expecting an "async advance" IRQ,
which comes from the processing passing the schedule head. Whether the
driver attempts to do such things is dependent on system timings, so
many folk would never have seen these problems.

This patch replaces the split ISO raw_mask calculation code in the
iso_stream_init() function that computed incorrect numbers of high
speed transactions for both input and output transfers.
In the output case, it added a superfluous start-split transaction for
all maxmimum packet sizes that are a multiple of 188.
In the input case, it forgot to add complete-split transactions for all
microframes covered by the full speed transaction, and the additional
complete-split transaction needed for the case when full speed data
starts arriving near the end of a microframe.
These changes don't affect the lack of full speed bandwidth, but at
least it removes the MMF errors that the HC raised with some input
streams.

This teaches the EHCI driver about a quirk seen in older NForce2 chips,
adding a workaround to ignore selective suspend requests. Bus-wide
(so-called "global") suspend still works, as does USB wakeup of a
root hub that's globally suspended.
There's still a hole in this support though. Strictly speaking, this
should _fail_ selective suspend requests, rather than ignoring them,
since doing it this way means that devices which should be able to issue
remote wakeup are not going to be able to do that. For now, we'll just
live with that problem ... since usbcore expects to do selective suspend
on the way towards a full bus suspend, and usbcore needs to be able to
do full bus suspend.

The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB

ISOSEND0=0 (the default value), the USB core does not respond to the IN
token. If ISOSEND0=1, the USB core sends a zero-length data packet in
response to the IN token. The action to take depends on the overall
system design. The ISOSEND0 Bit applies to all of the isochronous IN
endpoints, IN-8 through IN-15.

Change the module parameters rcv_buf_size and snd_buf_size to
specify buffer sizes in bytes rather than ATM cells. Since
there is some danger that users may not notice this change,
the parameters are renamed to rcv_buf_bytes etc. The transmit
buffer needs to be a multiple of the ATM cell size in length,
while the receive buffer should be a multiple of the endpoint
maxpacket size (this wasn't enforced before, which causes trouble
with isochronous transfers), so enforce these restrictions. Now
that the usbatm probe method inspects the endpoint maxpacket size,
minidriver bind routines need to set the correct alternate setting
for the interface in their bind routine. This is the reason for
the speedtch changes.

This patch causes vcc_release_async to be applied to any open

I wrote this patch because of reports that pppd would keep
connections open forever when the modem is disconnected.
This patch does not fix that problem, but it's a step in the
right direction. It doesn't help because the pppoatm module
doesn't yet monitor state changes on the ATM socket, so simply
never realises that the ATM connection has gone down (meaning
it doesn't tell the ppp layer). But at least there is a socket
state change now. Unfortunately this patch may create problems
for those rare users like me who use routed IP or some other
non-ppp connection method that goes via the ATM ARP daemon: the
daemon is buggy, and with this patch will crash when the modem
is disconnected. Users with a buggy atmarpd can simply restart
