No problem. I would be interested in using NimBLE to communicate between multiple devices (e.g. some RPis Zero W) in a mesh, like the microbit does in the image at...

Which QEMU did you tried? My own QEMU repo is outdated, that's true. The current version is maintained [here](https://github.com/smuehlst/qemu).

The QEMU version from [here](https://github.com/smuehlst/qemu) supports USB, even with AArch64. So this comment is not valid any more. You shouldn't use the `--qemu` option with `configure` of the *circle-stdlib* project,...

I tried the following again successfully on a PC/Linux host: ``` cd circle-stdlib configure -r 3 -p aarch64-none-elf- make -j cd samples/04-std make -j qemu-system-aarch64 -M raspi3b -kernel ./kernel8.img \...

That would be a big effort, because one have to analyze the Linux driver to extract the required information. I did this for the host mode and it wasn't fun....

At first your OS must provide some functions to USPi, so that it can work. These functions are declared in the header file [uspios.h](https://github.com/rsta2/uspi/blob/master/include/uspios.h). I had a quick look and...

OK. You need all services declared in [uspios.h](https://github.com/rsta2/uspi/blob/master/include/uspios.h) (e.g. memory allocation and timer too).

Unfortunately I cannot reproduce this problem. I tested this with two different keyboards. After holding a key for 40 seconds, both keyboards still respond. Maybe your keyboard switches off, after...

I tested with a RPi 2B.

This requires a complete rewrite of the USB host controller driver. It is not likely, that there will be a version of this project, which can be used with the...
