With those patches applied, I get good results on most things, for example:

Download a kernel .tar.xz file and write to built-in SD (at 2.5M/s!), a
few times, using the built-in USB-based wired Ethernet.

dd an entire USB-hosted SD card to /dev/null.

apt-get install a couple small packages while doing that dd.

Run "concordance" on a Logitech Harmony remote; identify it, and dump
the firmware and config to a file on SD card.

All that seemed to work fine.

I still have the issue where SD card plug/unplug from a USB SD reader
isn't recognized. Perhaps that's a kernel config issue, or perhaps there
are still some USB issues?

I then wanted to try WiFi, so I plugged in a USB mouse/keyboard, and
started X, trying to use GUI tools. Then I saw some issues.

With just the USB mouse/keyboard attached (via a powered hub), and no
WiFi device yet, they would work for a while, but pretty soon I kept
seeing all USB devices just disappear; only the "Linux Foundation 2.0
root hub" would be left. Unplugging and replugging didn't fix this; I
had to power-cycle.

I wonder if there are issues with just USB interrupt transfers, which I
assume both HID devices and the USB SD card plug/unplug notifications use??

I tried plugging in the WiFi device and no mouse/keyboard, and retrying
a download of a large file using the built-in USB wired Ethernet, and
that still worked fine.

Unfortunately, I need to read up a bit more on how to configure WiFi
without a GUI tool, or switch to Network Manager which I know how to
configure manually, before I can really test WiFi. "iwlist wlan0
scanning" did seem to work fine though.

So, definitely moving in the right direction:-) But, a few issues left yet.
