usb-linux: Get speed from sysfs rather then from the connectinfo ioctl
The connectinfo ioctl only differentiates between lo speed devices, andall other speeds, where as we would like to know the real speed. The realspeed is available in sysfs so use that when available....
usb-linux: Teach about super speed

usb-linux: Don't do perror when errno is not set
Note that "op" also is not set, so before this change these error pathswould feed NULL to perror.
usb-linux: Ensure devep != 0
So that we don't index endp_table with a negative index.
usb-linux: catch ENODEV in more places.
Factor out disconnect code (called when a device disappears) to aseparate function. Add a check for ENODEV errno to a few more placesto make sure we notice disconnects.
Fix compilation warning due to missing header for sigaction (followup)
This patch removes all references to signal.h when qemu-common.h is includedas they become redundant.

usb: move cancel callback to USBDeviceInfo
Remove the cancel callback from the USBPacket struct, move it overto USBDeviceInfo. Zap usb_defer_packet() which is obsolete now.
usb-linux: use usb_generic_handle_packet()

usb-linux: add hostport property
This patch adds a hostport property which allows to specify the host usbdevices to pass through by bus number and physical port. This means youcan basically hand over one (or more) of the usb plugs on your host tothe guest and whatever device is plugged in there will show up in the...
usb-linux: track aurbs in list
This patch adds code to track all async urbs in a linked list,so we can find them without having to pass around a opaquepointer to them. Prerequisite for the cleanups.
usb-linux: walk async urb list in cancel
Lookup async urbs which are to be canceled using the linked listinstead of the direct opaque pointer. There are two reasons weare doing that: First, to avoid the opaque poiner to the callback,which is needed for upcoming cleanups. Second, because we might...
usb-linux: split large xfers
Add support for splitting large transfers into multiple smaller ones.This is needed for the upcoming EHCI emulation which allows gueststo submit requests up to 20k in size. The linux kernel allows 16kmax size though.
Based on a patch from David Ahern, see...
usb-linux: fix max_packet_size for highspeed.

usb-linux: Add support for buffering iso usb packets
Currently we are submitting iso packets to the host one at a time, as wereceive them from the emulated host controller. This has 2 problems:1) If we were fast enough to submit every packet in time for the next host host...
usb-linux: Refuse packets for endpoints which are not in the usb descriptor
If an endpoint is not in the usb descriptor we've no idea what kind ofendpoint it is and thus how to handle it, refuse packages in this case.
usb-linux: Refuse iso packets when max packet size is 0 (alt setting 0)
Refuse iso usb packets when then max packet size for the endpoint is 0,this avoids an abort in usb_host_alloc_iso() caused by trying to qemu_malloca 0 bytes large buffer.
usb-linux: We only need to keep track of 15 endpoints
Currently we reserve room for endpoint data for 16 endpoints, but giventhat we only use endpoint data for endpoints 1-15, and always index thearray with the endpoint-number - 1, 15 is enough.
usb-linux: Add support for buffering iso out usb packets
Extend the iso buffering code to also buffer iso out packets, thisfixes for example using usb speakers with usb redirection.
