2006-07-12[PATCH] USB: rename Cypress CY7C63xxx driver to proper name and fix up some ↵Oliver Bock
tiny things 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.

2006-06-21[PATCH] usbtest: report errors in iso testsAlan Stern
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! Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-06-21[PATCH] Fix a deadlock in usbtestFranck Bui-Huu
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.

2006-05-12[PATCH] USB: Emagic USB firmware loading fixesMonty
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.

2006-04-14[PATCH] USB: usbtest: scatterlist OUT data pattern testingDavid Brownell
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.

2005-10-28[PATCH] usb_interface power stateDavid Brownell
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.

2005-09-12[PATCH] USB: sisusb[vga] updateThomas Winischhofer
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.

2005-09-08[PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern
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."

2005-07-12[PATCH] USB: add ldusb driverMichael Hund
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. Signed-off-by: Michael Hund <mhund@ld-didactic.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
