Lots of users are getting confused about the cp2101 driver. It really does support more than just the cp2101 device, so rename it to cp210x to try to prevent confusion. Cc: Craig Shelley <craig@microtron.org.uk> Signed-off-by: -

This patch adds support for the extended range of baud rates supported by CP2102 and CP2103 devices described in SiLabs AN205. An additional function cp2101_quantise_baudrate rounds the baud rate as per AN205 Table 1. A modification to the baud rate calculation removes a rounding error, allowing the full range of baud rates to be used. Signed-off-by:

This patch (as1221) changes the way usbcore reinitializes a device following a reset or a reset-resume. Currently we call usb_set_interface() for every interface in the active configuration; this is to put the interface into the same altsetting as before the reset and to make sure that the host's endpoint state matches the device's endpoint state. However, sending a Set-Interface request is a waste of time if an interface was already in altsetting 0 before the reset, since it is certainly in altsetting 0 afterward. In addition, many devices can't handle Set-Interface requests -- they crash when they receive them. So instead, the patch adds code to check each interface. If the interface wasn't in altsetting 0 before the reset, we go head with the Set-Interface request as before. But if it was then we skip sending the Set-Interface request, and we clear out the host-side endpoint state by calling usb_disable_interface() followed by usb_enable_interface(). The patch also adds a couple of new comments to explain what's going on. Signed-off-by:

actual_length should also be a u32 and not a signed value. This patch changes this field to be 'u32' to prevent any potential negative conversion and comparison errors. This triggered a few compiler warning messages when these fields were being used with the min macro, so they have also been fixed up in this patch.

The code in uhci-q.c doesn't have to use pseudo-negative values. I did it that way because it was easy and because it would give the expected output during debugging. But it doesn't have to work that way. Here's another approach. Signed-off-by:

This patch fixes the following bug: .plug ch341 usb serial port into a hub port; .ch341 driver bound to the device and /dev/ttyUSB0 comes .open /dev/ttyUSB0 by minicom and we can use the serial successfully .suspend the ch341 usb serial device(such as: echo suspend > power/level) .resume the ch341 usb serial device (such as: echo on > power/level) .new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists, but is no longer usable by minicom The patch adds suspend and resume callback to ch341 usb driver to prevent it from unbinding during suspend. The /dev/ttyUSB0 is not released until being closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is no longer usable by minicom. It is really a mess for a minicom user. This patch also adds the reset_resume callback to make it usable after resuming from STR or hibernation, for generally STR or hibernation will make the vbus of root-hub lost. Finally enable the driver's supports_autosuspend, for the device is in working order with it. Signed-off-by:

Partial support for DaVinci DM355, on the EVM board; peripheral mode should work, once mainline merges DM355 support. Missing: (a) renumbering the GPIO for DRVVBUS on the DM6446 EVM, when DAVINCI_N_GPIO increases; (b) disabling DM355_DEEPSLEEP.DRVVBUS_OVERRIDE so VBUS is driven according to the ID signal, if cpu_is_..._dm355() The new PHY control bits are ignored on DM6446.

Except on DaVinci, VBUS is now switched off as part of idling the USB link (after a_wait_bcon) whenever a device is disconnected from host. This is correct for OTG hosts, where either SRP or an ID interrupt could turn VBUS on again. However, for non-OTG hosts there's no way to turn VBUS on again, so the host becomes unusable. And the procfs entry which once allowed a manual workaround for this is now gone. This patch adds an is_otg_enabled() check before scheduling the switch-off timer in disconnect path, supporting a "classic host" mode where SRP is unavailable.

Fixes endpoint starvation issue when more than one bulk QH is multiplexed on the reserved bulk RX endpoint, which is normal for cases like serial and ethernet adapters. This patch sets the NAK timeout interval for such QHs, and when a timeout triggers the next QH will be scheduled. (This resembles the bulk scheduling done in hardware by EHCI, OHCI, and UHCI.) This scheme doesn't work for devices which are connected to a high to full speed tree (transaction translator) as there is no NAK timeout interrupt from the musb controller from such devices. Tested with PIO, Inventra DMA, CPPI DMA. [ dbrownell@users.sourceforge.net: fold in start_urb() update; clarify only for bulk RX; don't accidentally clear WZC bits ] Signed-off-by:

The current MUSB host code doesn't make use of all the available FIFOs in for periodic transfers since it wrongly assumes the RX and TX sides of any given hw_ep always share one FIFO. Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep' to check the endpoint's business; get rid of the now-unused 'periodic' array in the 'struct musb'. Also optimize a loop induction variable in the endpoint lookup code.

To permit a userspace application to associate with WUSB devices using numeric association, control transfers to unauthenticated WUSB devices must be allowed. This requires that wusbcore correctly sets the device state to UNAUTHENTICATED, DEFAULT and ADDRESS and that control transfers can be performed to UNAUTHENTICATED devices. Signed-off-by:

This patch (as1207) converts usb-storage's sddr09 subdriver into a separate module. An unexpected complication arises because of DPCM devices, in which one LUN uses the sddr09 transport and one uses the standard CB transport. Since these devices can be used even when USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h require special treatment. If SDDR09 isn't configured then the entries remain in unusual_devs.h; if it is then the entries are present in unusual_sddr09.h instead. Signed-off-by:

This patch (as1206) is the first step in converting usb-storage's subdrivers into separate modules. It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions. Signed-off-by:

With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it. Signed-off-by:
