@ rb2013: FYI firmware updating on XMOS processors was enabled wayyyyy back and not come with this latest chip release! I used it for my WaveIOs starting back in 2012 when I've update its stock firmware (24/192) to 32/384 capabilities and I'm using it right now. In fact, that chip (XS1-L1A-TQ128) was the oldest possible chip I know made by XMOS. The update is made through USB DFU functionality (DFU = Device Firmware Update). I don't know if it's permitted to share some external links but look for WaveIO's thread on Diyaudio where there are plenty of questions regarding how to upload a new firmware over a stock one. Anyway, here's a link for such a procedure starting back in 2014 - look at the date in upper left side of my post (it can be deleted by moderators if this is their will). This "supports firmware upgrade interface" text is put there only for marketing purposes so that unaware buyers will believe it's a whole new thing and was never made before.Chinese, as always deceive and (possible) steal...
I also really hope this board does NOT come with hacked Luckit drivers like a multitude of other chinese/SK/HK ones found on Aliexpress, Taobao, eBay, etc does!
All infos above are shared only to warn you to not blindly believe what others are saying...
I hope it helps,

Hi -Thanks for the clarification. After owning a handful of XMOS U-8 based boards from Gustard, Melodious, Breeze, DIYinHK, etc...I have never seen this capability mentioned. So I took their word for it that is was a new feature or at least the firmware updating was easier (software based).
It does say on the XMOS website on the new Xcore 200 series: http://www.xmos.com/products/silicon/xcore-200
Three device families provide a range of price points and functionality to suit any application: the unique benefits of flexibility and determinism offered by the xCORE architecture are extended with the provision of increased memory footprint, optional integrated Flash, Gigabit Ethernet and USB 2.0 PHY.So it was the reference to the 'optional integrated Flash' is what lead me to believe this was a new feature.
On the XMOS website in reference to the USB specific chip the XU200/XUF200 Series they say: http://www.xmos.com/products/silicon/xcore-200/xu-series
xCORE-200 XU/XUF integrates up to two USB 2.0 PHYs (host or device) and implements a dual-issue processor pipeline to boost peak compute performance to 4000MIPS and 2000MMACS. Up to 1024KB on-chip SRAM memory is available. Each member of the xCORE-200 family has an embedded flash option for applications where additional security is required.
Embedded QuadSPI flash options - up to 2048KB on-board.
The XMOS driver was labeled 'Singxer USB Audio'.
