| * | usb-storage: use first bulk endpoints, not lastAlan Stern2007-02-071-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the Bulk-Only spec, usb-storage is supposed to use the _first_ bulk-in and bulk-out endpoints it finds, not the _last_. And while we're at it, we ought to test the direction of the interrupt endpoint as well. This patch (as842) makes both changes.

| * | EHCI: fix interrupt-driven remote wakeupAlan Stern2007-02-071-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that port status change notifications are interrupt-driven, ehci-hcd needs to tell usbcore when a remote-wakeup resume operation is finished -- we can no longer rely on the core to poll and find out. This patch (as843) uses the root-hub status timer to force a poll after the resume is complete. The patch also changes the test for detecting when the TDRSMDN resume period has expired. It's necessary to use time_after_eq() instead of time_after(), since the polling is triggered precisely by a timer. The same change is made for TDRSTR reset expiration, for consistency.

| * | USB: switch ehci-hcd to new polling schemeMarcelo Tosatti2007-02-071-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch ehci-hcd to use the new polling scheme, which reports root hub status changes via the interrupt handler, in an asynchronous fashion. Doing so disables polling for status changes (whose handler is rh_timer_func). Tested on a Geode GX machine, which is now capable of running at =~ 5 timer interrupts per second (in the -rt tree), resulting in significant power savings.

| * | USB: gadgetfs AIO tweaksAlan Stern2007-02-071-9/+7

The extra call to aio_put_req() causes memory corruption. (Note: This call was removed before, by patch as691, and then mysteriously re-introduced later.) Even if a read transfer is cancelled, we can and should send to the user all the data that did manage to get transferred. Testing for AIO cancellation in the I/O completion handler is both racy and (now) unnecessary. aio_complete() does its own checking, in a safe manner.

| * | fix for bugzilla #7544 (keyspan USB-to-serial converter)Rainer Weikusat2007-02-071-4/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least the Keyspan USA-19HS USB-to-serial converter supports two different configurations, one where the input endpoints have interrupt transfer type and one where they are bulk endpoints. The default UHCI configuration uses the interrupt input endpoints. The keyspan driver, OTOH, assumes that the device has only bulk endpoints (all URBs are initialized by calling usb_fill_bulk_urb in keyspan.c/ keyspan_setup_urb). This causes the interval field of the input URBs to have a value of zero instead of one, which 'accidentally' worked with Linux at least up to 2.6.17.11 but stopped to with 2.6.18, which changed the UHCI support code handling URBs for interrupt endpoints. The patch below modifies to driver to initialize its input URBs either as interrupt or as bulk URBs, depending on the transfertype contained in the associated endpoint descriptor (only tested with the default configuration) enabling the driver to again receive data from the serial converter. Greg K-H reworked the patch. Signed-off-by: Rainer Weikusat <rweikusat@sncag.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | EHCI: force high-speed devices to run at full speedAlan Stern2007-02-073-1/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as710) adds a sysfs class-device attribute file named "companion" for EHCI controllers. The file contains a list of port numbers that are dedicated to the companion controller; by writing a port number to the file the user can force a high-speed device attached directly to the computer to run at full speed. (As far as I know it is not possible to do this for a device attached to an external hub.) A port is removed from the file by writing the negative of its port number. Several users have asked for this facility and it seems like a useful thing to have. Every now and then one runs across a device which behaves much better at full speed than at high speed.

The new API allows for less CPU use, and it allows to capture all data from a packet where old API only captured 32 bytes at most. There are some limitations and conditions to this, e.g. in case someone constructs a URB with 1GB of data, it's not likely to be captured, because even the huge buffers of the new reader are finite. Nonetheless, I expect this new capability to capture all data for all real life scenarios. The downside is, a special user mode application is required where cat(1) worked before. I have sample code at http://people.redhat.com/zaitcev/linux/ and Paolo Abeni is working on patching libpcap.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few things and getting it all working properly. This adds support for dynamic usb ids to the usb serial core. The file "new_id" will show up under the usb serial driver, not the usb driver associated with the usb-serial driver (yeah, it can be a bit confusing at first glance...) This patch also modifies the USB core to allow the usb-serial core to reuse much of the dynamic id logic.

| * | ohci: Add support for OHCI controller on the of_platform busSylvain Munaut2007-02-073-1/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PPC embedded systems can have a ohci controller builtin. In the new model, it will end up as a driver on the of_platform bus, this patches takes care of them.

| * | ohci: Rework bus glue integration to allow several at onceSylvain Munaut2007-02-0713-198/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.

| * | rndis_host learns ActiveSync basicsOle Andre Vadla Ravnas2007-02-074-31/+144

This patch updates the cdc ethernet code to fake ACM descriptors we need. - Require RNDIS_MSG_QUERY messages to include a buffer of the size the response should generate. This patch updates the rndis host code to pass this will-be-ignored data. The resulting RNDIS host code has been reported to work with several WM5 based devices. (Note that a fancier patch is available at synce.sf.net.) Some bugfixes, affecting not just ActiveSync: (a) when cleaning up after RNDS init fails, scrub the second interface just like cdc_ether does, so disconnect won't oops. (b) handle peripherals that use the pad-to-end-of-packet option; some devices can't talk to us if that option doesn't work. (c) when choosing configurations, don't forget about an RNDIS config just because the RNDIS driver is dynamically linked. Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update. Also for paranoia's sake, refuse to talk to something that looks like a real modem instead of RNDIS.

| * | USB: ethernet gadget interop with MCCI Windows driverDavid Brownell2007-02-071-39/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)
