No need to set latency timeout at every open. This also fixes an issue with the read latency being as high as 250ms (instead of 1ms) for the first read after port probe. Signed-off-by:

If the iowarrior devices in this case statement support more than 8 bytes per report, it is possible to write past the end of a kernel heap allocation. This will probably never be possible, but change the allocation to be more defensive anyway. Signed-off-by:

This patch for FTDI USB serial driver ads new VID/PIDs used on various devices manufactured by Papouch (http://www.papouch.com). These devices have their own VID/PID, although they're using standard FTDI chip. In ftdi_sio.c, I also made small cleanup to have declarations for all Papouch devices together. Signed-off-by:

This commit changes storage_common.h, file_storage.c and f_mass_storage.c to use definitions of SCSI commands from scsi/scsi.h file instead of redefining the commands in storage_common.c. scsi/scsi.h header file was missing READ_FORMAT_CAPACITIES and READ_HEADER so this commit also add those to the header.

At otg device mode, the otg host resume should do no-op during system resume, otherwise, the otg device will be treated as a host for enumeration. So, the otg host driver returns -ESHUTDOWN if it detects the current usb mode is device mode. The host driver has to return -ESHUTDOWN, otherwise, the usb_hc_died will be called. Signed-off-by:

I seem to have a knack for digging up buggy usb devices which don't work with Linux, and I'm crazy enough to try to make them work. So this time a friend of mine asked me to get an mp4 player (an mp3 player which can play videos on a small screen) to work with Linux. It is based on the well known rockbox chipset for which we already have an unusual devs entries to work around some of its bugs. But this model comes with an additional twist. This model chokes on read_capacity_16 calls. Now normally we don't make those calls, but this model comes with an sdcard slot and when there is no card in there (and shipped from the factory there is none), it reports a size of 0. However this time the programmers actually got the read_capacity_10 response right! So they substract one from the size as stored internally in the mp3 player before reporting it back, resulting in an answer of ... 0xffffffff sectors, causing sd.c to try a read_capacity_16, on which the device crashes. This patch adds a flag to scsi_device to indicate that a a device cannot handle read_capacity_16, and when this flag is set if a device reports an lba of 0xffffffff as answer to a read_capacity_10, assumes it tries to report a size of 0.

Appotech ax3003 (the larger brother of the ax203) based devices are even more buggy then the ax203. They will go of into lala land when ever they see a READ_DISC_INFO scsi command.

Some USB devices emulate a usb-mass-storage attached (scsi) cdrom device, usually this fake cdrom contains the windows software for the device. While working on supporting Appotech ax3003 based photoframes, which do this I discovered that they will go of into lala land when ever they see a READ_DISC_INFO scsi command. Thus this patch adds a scsi_device flag (which can then be set by the usb-storage driver through an unsual-devs entry), to indicate this, and makes the sr driver honor this flag. I know this sucks, but as discussed on linux-scsi list there is no other way to make this device work properly. Looking at usb traces made under windows, windows never sends a READ_DISC_INFO during normal interactions with a usb cdrom device. So as this cdrom emulation thingie becomes more common we might see more of this problem. Signed-off-by:

This is based on an initial patch by Rahul Ruikar. The goku_remove() function can be called before device_register() so it can call device_unregister() improperly. Also if the call to device_register() fails we need to call put_device(). As I was changing the error handling in goku_probe(), I noticed that the label was "done" but actually if the function succeeds we return earlier. I renamed the error path to "err" instead of "done."

The hardware can only do DMA to 4 byte aligned addresses. When this requirement is not met use PIO or a bounce buffer. PIO is used when the buffer is small enough to directly use the hardware data memory (2*maxpacket). A bounce buffer is used for larger transfers. Signed-off-by:

This patch (as1430) fixes a bug in usbcore. When a device configuration change occurs or a device is removed, the endpoints for the old config should be completely disabled. However it turns out they aren't; this is because usb_unbind_interface() calls usb_enable_interface() or usb_set_interface() to put interfaces back in altsetting 0, which re-enables the interfaces' endpoints. As a result, when a device goes through a config change or is unconfigured, the ep_in[] and ep_out[] arrays may be left holding old pointers to usb_host_endpoint structures. If the device is deauthorized these structures get freed, and the stale pointers cause errors when the the device is eventually unplugged. The solution is to disable the endpoints after unbinding the interfaces instead of before. This isn't as large a change as it sounds, since usb_unbind_interface() disables all the interface's endpoints anyway before calling the driver's disconnect routine, unless the driver claims to support "soft" unbind. This fixes Bugzilla #19192. Thanks to "Tom" Lei Ming for diagnosing the underlying cause of the problem. Signed-off-by:

Since commit 461972d8 (musb_core: don't call musb_platform_exit() twice), unloading the driver module results in a WARNING "kobject: '(null)' (c73de788): is not initialized, yet kobject_put() is being called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode. There exists dubious and unbalanced put_device() call in musb_free() which takes place only in the OTG mode. As this commit caused musb_platform_exit() to be called (and so unregister the NOP transceiver) before this put_device() call, this function references already freed memory. On the other hand, all the glue layers miss the otg_put_transceiver() call, complementary to the otg_get_transceiver() call that they do. So, I think the solution is to get rid of the strange put_device() call, and instead call otg_put_transceiver() in the glue layers... Signed-off-by:

Extends FSL EHCI platform driver glue layer to support MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI registers are in big endian format. The appropriate flags are set using the information in the platform data structure. MPC83xx system interface registers are not available on MPC512x, so the access to these registers is isolated in MPC512x case. Furthermore the USB controller clocks must be enabled before 512x register accesses which is done by providing platform specific init callback. The MPC512x internal USB PHY doesn't provide supply voltage. For boards using different power switches allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties in the device tree USB nodes. Adds documentation for this new device tree bindings. Signed-off-by:

Replace FSL USB platform code by simple platform driver for creation of FSL USB platform devices. The driver creates platform devices based on the information from USB nodes in the flat device tree. This is the replacement for old arch fsl_soc usb code removed by this patch. The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices. The new of-style driver additionaly instantiates USB OTG platform device, as the appropriate USB OTG driver will be added soon. Signed-off-by:

commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke g_file_storage functionality by enabling AUTOCLEAR on all cases without caring for all gadget drivers. This patch will only enable AUTOCLEAR if our endpoint's FIFO was configured with double buffering support. Note this is not a complete fix, double buffered case still doesn't work always, but that hasn't been working for quite some time. Other than reverting the entire commit and breaking testusb with double buffered case again, I decided it was better to fix the single buffered case and spend more time fixing double buffered case properly.
