I upgraded to Diablo. Unlike those in other posts, my battery life seems to be superior. But I had only just installed "usb host control," on my OS2007.51.3 os so that I could use a usb keyboard, and thumb drive. Not knowing better, I returned to maemo to download the program again for Diablo. But Diablo gave me an error message. So, I'm thinking I read that usb control is already in Diablo. That brought me here. Now I read that some people have some form of usb control, accessible through control pane. I do not! Neither do I find anything remotely useful in "Installable applications." Duh!
