Thanks, ukki! That works great, and addresses future things I will likely try (like USB wired internet).

For the rest of you, I too had this same problem with USB Control -- it simply will no longer run/start. I uninstalled it and reinstalled it, and it still will not run. I reset my N810 between uninstall/reinstall as well as after the reinstall. Still will not start. I tap on the icon and nothing. I check for the processes running via the Load Applet app and I do not see USB Control or anything that could actually be it running under an alternative name.

This happened out of the blue and all of a sudden. I've been using USB Control without issue since I got my N810 in mid-June 2009. I've been using memory sticks, card readers, etc., without issue. Now...nothing. I did do the usual thing for new N810 owners -- tried just about every piece of software that I could get my hands on, but after figuring out what I wanted to run on my N810 all the time, I reflashed it and loaded just those very few apps, including USB Control. It worked fine just a couple of days ago, and I've installed nothing since (until the usb-otg-plugin just now).

Oh, well.
