Xiao with USB high speed interface

[ckrenslehner]

Hi! Are you planning to design a Xiao which features a high speed USB interface?

I find this interesting in terms of developing a CMSIS DAP compatible debug probe based on the Xiao form factor.

Thanks und regards,
Christian

I suspect the issue here is more a limitation on the software side, unless you need more than 1mb of speed. A lot of the newer chips support usb 2.0, though the teensy 4.x boards are the only ones I know of that can make use of it (and fully utilize the bandwidth).

I don't really know to be honest. I will try a Xiao compatible port of a rp2040 picoprobe firmware and test the speed. :-)
Thanks

Please do let me know if you get it running at a good speed. Its been a while since I've investigated it, and while the hardware is supposedly capable, the software didn't support it at all at that time. I could certainly make use of it for HID devices.
