https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/transfer-data-to-isochronous-endpoints
This topic describes how a client driver can build a USB Request Block (URB) to transfer data to and from isochronous endpoints in a USB device. A Universal Serial Bus (USB) device can support isochronous endpoints to transfer time-dependent data at a …

A USB device can support isochronous endpoints to transfer time-dependent data at a steady rate, such as with audio/video streaming. There is no guaranteed delivery. A good connection shouldn’t drop any packets, it is not normal or expected to lose packets, but the isochronous …

Jun 27, 2005 · I run SmoothWall Express 2.0 firewall in a guest VM. VMware and SmoothWall make an excellent combination but due to the lack of support for isochronous USB mode I had to downgrade to analog modem connection instead of using the full ISDN speed. Please add isochronous USB mode to Vmware soon! Stefan

If considering third-party USB solutions other than those listed below, bear in mind that the device must support isochronous data transfer in order to successfully carry audio over USB. If USB 3.0 options are used they must be backwards compatible with USB 2.0 devices.

To explain the need for this final new isochronous feature in USB 3.1, take the example of an isochronous IN endpoint on a USB 3.0 device that can return 4 packets per microframe. When the entire topology is running at USB 3.0 speeds and hubs are not buffering data, it is relatively efficient for the host to request the 4 packets, 2 at a time.

Feb 06, 2010 · I have an application where I need two isochronous IN endpoints with a rather large payload (375 to 500 bytes). The C55x USB sample code that I have only has partial isochronous source code which is incomplete and commented out. Has anyone successfully used the CSL USB support for Full Speed bandwidth isochronous data transfer?

Apr 18, 2018 · The stop message indicates that the USB streaming device driver using USBCAMD2 submitted two IRPs to initiate Isochronous data transfers, both of which referenced the same URB (USB Request Block) to describe the Isochronous data transfers.
https://en.wikipedia.org/wiki/Isochronous
Isochronous burst transmission is used when the information-bearer channel rate is higher than the input data signaling rate. In the Universal Serial Bus used in computers, isochronous is one of the four data flow types for USB devices (the others being Control, Interrupt and Bulk). It is commonly used for streaming data types such as video or ...

The above three packets represent the first USB transaction. The USB device will now decode the 8 bytes received, and determine if it was a device descriptor request. The device will then attempt to send the Device Descriptor, which will be the next USB transaction.
