I'm not a hardware guy, too. I have opinions about how things *should*
work, however (eg. "work as advertised").

Maybe. Without researching the archives right now, I was under the
impression that this longstanding issue was resolved with the latest
version of the hard- and software, and announced as such weeks or
months ago on one of the mailing lists, or the wiki. I may be mistaken,
and/or maybe a bug has crept back in, but this *should* *work*.

I was unable to determine exactly the point where the device crashes,
but if I could find that out, maybe there'd be a way to load the USB
drivers earlier? But then, I'd first need to learn how to create my own
kernels for the device. If you have tips for me... compiling on the
device will certainly be a pain, but using some kind of cross-compiling
toolchain should be possible.

Kind regards,
