The following patch removes the call to usb_reset_device which may occur when closing the driver by implementing a new session initialization code based on the method used by gpsbabel. The patch is against linux-2.6.30-rc3-git1. Signed-off-by: Hermann Kneissel herkne@users.sourceforge.net Signed-off-by:Greg Kroah-Hartman <gregkh@suse.de>

This patch (as1237) changes the way the PCI host controller drivers avoid retaining bogus hardware states during resume-from-hibernation. Previously we had reset the hardware as part of preparing to reinstate the memory image. But we can do better now with the new PM framework, since we know exactly which resume operations are from hibernation. The pci_resume method is changed to accept a flag indicating whether the system is resuming from hibernation. When this flag is set, the drivers will reset the hardware to get rid of any existing state. Similarly, the pci_suspend method is changed to remove the pm_message_t argument. It's no longer needed, since no special action has to be taken when preparing to reinstate the memory image. Signed-off-by:

- Version number set to 1.3.5 - Added "\n" at the end of each string in dev_dbg() code to improve the debug information visibility. Without this change the debug logs are very difficult to read. Signed-off-by:

- Version number set to 1.3.4 - Increased the number of input/output URBs for improved performance (numbers based on an measurement study triggered by a user request). We performed the testing using a network simulator that provided full speeds in the uplink and downlink directions and this combination of URBs provided the best throughput. Signed-off-by:

The usb_host class isn't used for anything anymore (it was used for debug files, but they have moved to debugfs a few kernel releases ago), so let's delete it before someone accidentally puts a file in it. Signed-off-by: -

Right now we jump through some hoops to get to the struct ohci_hcd struct in the ohci debugfs files. Remove all of the fun casting around and just use the pointer directly. This is needed as the dev pointer in the hcd structure is going away, and it makes the code simpler and smaller Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: -

This patch (as1239) updates the kernel's treatment of Unicode. The character-set conversion routines are well behind the current state of the Unicode specification: They don't recognize the existence of code points beyond plane 0 or of surrogate pairs in the UTF-16 encoding. The old wchar_t 16-bit type is retained because it's still used in lots of places. This shouldn't cause any new problems; if a conversion now results in an invalid 16-bit code then before it must have yielded an undefined code. Difficult-to-read names like "utf_mbstowcs" are replaced with more transparent names like "utf8s_to_utf16s" and the ordering of the parameters is rationalized (buffer lengths come immediate after the pointers they refer to, and the inputs precede the outputs). Fortunately the low-level conversion routines are used in only a few places; the interfaces to the higher-level uni2char and char2uni methods have been left unchanged. Signed-off-by:

Clemens Ladisch authored
utf8_wcstombs forgot to include one-byte UTF-8 characters when calculating the output buffer size, i.e., theoretically, it was possible to overflow the output buffer with an input string that contains enough ASCII characters. In practice, this was no problem because the only user so far (VFAT) always uses a big enough output buffer. Signed-off-by:

Clemens Ladisch authored
When utf8_wcstombs encounters a character that cannot be encoded, we must not decrease the remaining output buffer size because nothing has been written to the output buffer. Signed-off-by:

People are very used to the devices file in usbfs. Now that we have moved usbfs to be an "embedded" option only, the developers miss the file, they had grown quite attached to it over all of these years. This patch brings it back and puts it in the usb debugfs directory, so that the developers don't feel sad anymore. Signed-off-by: -

Since the PXA 27x UDC automatically ACK's some control packets such as SET_INTERFACE, the gadgets may not get a chance to process the request before another control packet is received. The Linux gadgets do not expect to receive setup callbacks out of order. The file storage gadget only saves the "highest" priority request. The PXA27x UDC driver must make sure it only sends one up at a time, allowing the gadget to make changes before continuing. In theory, the host would be NACK'd while the gadget processes the change but the UDC has already ACK'd the request. If another request is sent by the host that is not automatically ACK'd by the UDC, then the throttling happens properly to regain sync. The observed case was the file_storage gadget timing out on a BulkReset request because the SET_INTERFACE was being processed by the gadget. Since SET_INTERFACE is higher priority than BulkReset, the BulkReset was dropped. This was exacerbated by turning on the debug which delayed the fsg signal processing thread. This also fixes the "should never get in WAIT_ACK_SET_CONF_INTERF state here!!!" warning. Reported-by:

Got pxa27x_udc working on the pxa320 Nomad platform. The problem was that the pxa3xx UDC is not quite compatible with the pxa27x UDC in how it handles back-to-back control packets. The pxa27x probably drops them by default, but the pxa320 does not, and you have to detect it and set the OPC bit to clear the zero-length packet. Signed-off-by:

Modern systems do not use usbfs; the entries within it are files, not device nodes, and do not support ACLs which are the default way to provide access to USB devices to untrusted users. It is replaced by device-nodes maintained by udev in /dev/bus/usb, libusb uses this device nodes. Mark the option as deprecated, and hide entirely for non-embedded builds (which may not be using udev but require raw USB device access). Signed-off-by:

This patch (as1230) consolidates code in usb_unbind_interface() and usb_driver_release_interface(). In fact, it makes release_interface call unbind_interface, thereby removing the need for duplicated code. It works like this: If the interface has already been registered with the driver core when a driver releases it, then the usual driver-core mechanism will call unbind_interface. If it hasn't been unregistered then we will make the call ourselves. As a nice bonus, drivers now don't have to worry about whether their disconnect method will get called when they release an interface -- it always will. Previously it would be called only if the interface was registered. Signed-off-by:

Added a function to set the packet size to be used based on the value from the device endpoint descriptor. The FT2232H and FT4232H hi-speed devices will have wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by:

Added support for FTDI's USB 2.0 hi-speed devices - FT2232H (2 interfaces) and FT4232H (4 interfaces), including a new baud rate calculation for these devices which can now achieve up to 12Mbaud by turning off a divide by 2.5 in the baud rate generator of the chips. In order to achieve baud rates of <1200 baud, the divide by 2.5 must be active. The default product ID of the FT2232H is 0x6010 (same as the FT2232C IC). The default PID of the FT4232H is 0x6011.
