I tried a magnetic stripe reader (http://www.kimaldi.com/kimaldi_eng/productos/lectores_de_tarjetas/lectores_tarjeta_chip_y_dni/lector_hibrido_uniform_hcr_331) and I see that it is interfaced with a PL2303.

2010-04-30USB: xhci: properly set endpoint context fields for periodic eps.Sarah Sharp
For periodic endpoints, we must let the xHCI hardware know the maximum payload an endpoint can transfer in one service interval. The xHCI specification refers to this as the Maximum Endpoint Service Interval Time Payload (Max ESIT Payload). This is used by the hardware for bandwidth management and scheduling of packets. For SuperSpeed endpoints, the maximum is calculated by multiplying the max packet size by the number of bursts and the number of opportunities to transfer within a service interval (the Mult field of the SuperSpeed Endpoint companion descriptor). Devices advertise this in the wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor. For high speed devices, this is taken by multiplying the max packet size by the "number of additional transaction opportunities per microframe" (the high bits of the wMaxPacketSize field in the endpoint descriptor). For FS/LS devices, this is just the max packet size. The other thing we must set in the endpoint context is the Average TRB Length. This is supposed to be the average of the total bytes in the transfer descriptor (TD), divided by the number of transfer request blocks (TRBs) it takes to describe the TD. This gives the host controller an indication of whether the driver will be enqueuing a scatter gather list with many entries comprised of small buffers, or one contiguous buffer. It also takes into account the number of extra TRBs you need for every TD. This includes No-op TRBs and Link TRBs used to link ring segments together. Some drivers may choose to chain an Event Data TRB on the end of every TD, thus increasing the average number of TRBs per TD. The Linux xHCI driver does not use Event Data TRBs. In theory, if there was an API to allow drivers to state what their bandwidth requirements are, we could set this field accurately. For now, we set it to the same number as the Max ESIT payload. The Average TRB Length should also be set for bulk and control endpoints, but I have no idea how to guess what it should be.

2010-04-30USB: xhci: properly set the "Mult" field of the endpoint context.Sarah Sharp
A SuperSpeed interrupt or isochronous endpoint can define the number of "burst transactions" it can handle in a service interval. This is indicated by the "Mult" bits in the bmAttributes of the SuperSpeed Endpoint Companion Descriptor. For example, if it has a max packet size of 1024, a max burst of 11, and a mult of 3, the host may send 33 1024-byte packets in one service interval. We must tell the xHCI host controller the number of multiple service opportunities (mults) the device can handle when the endpoint is installed. We do that by setting the Mult field of the Endpoint Context before a configure endpoint command is sent down. The Mult field is invalid for control or bulk SuperSpeed endpoints.

2010-04-30USB: OHCI: don't look at the root hub to get the number of portsAlan Stern
This patch (as1371) fixes a small bug in ohci-hcd. The HCD already knows how many ports the controller has; there's no need to go looking at the root hub's usb_device structure to find out. Especially since the root hub's maxchild value is set correctly only while the root hub is bound to the hub driver.

2010-04-30USB: don't choose configs with no interfacesAlan Stern
This patch (as1372) fixes a bug in the routine that chooses the default configuration to install when a new USB device is detected. The algorithm is supposed to look for a config whose first interface is for a non-vendor-specific class. But the way it's currently written, it will also accept a config with no interfaces at all, which is not very useful. (Believe it or not, such things do exist.)

2010-04-30usb: Fix tusb6010 for DMA APITony Lindgren
Commit 18eabe2347ae7a11b3db768695913724166dfb0e introduced DMA buffer ownership. Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem.

2010-04-27net/usb: add sierra_net.c driverElina Pasheva
Re-submitted based on comments from netdev community. Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

As the i2c controller can sleep while sending a message, this qualifies as a bad idea.

2010-04-27bnx2: Prevent "scheduling while atomic" warning with cnic, bonding and vlan.Michael Chan
The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

2010-04-27bnx2: Fix lost MSI-X problem on 5709 NICs.Michael Chan
It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

2010-04-27e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errataBruce Allan
Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

2010-04-27ixgbe: Power down PHY during driver resetsPeter Waskiewicz
