Wait, do you have to be in Root on your 770 for these commands to work(sudo gainroot)? Because when I try them in root, they don't work.

Yes, you need to be root. Are you getting an error message, or are they just not working?

Since I do not use the flasher to put the device in host mode, I dont know if that is what is blocking you. Try this:
Use the flasher to put the 770 in peripheral mode (normal mode)
Issue the host command as root (note the device does not appear to be in host mode)
check dmesg, your device should be listed
mount the drive or whatever
when you are done issue the peripheral command to put back in peripheral mode
I just use it to access a external USB hard drive and it works great. I have always entered USB-host mode by using the terminal.

Using the Flasher *forces* USB host mode. However, if the USB is set to device mode, the above commands will allow you to enable host mode temporarily (i.e. until you execute the command on the device to return to device mode, or reboot)
This is almost always going to be better for you, as USB host mode disables some of the power management facilities; resulting in a faster draining battery.

Apologies for being the whiny end-user here (I'm VERY new to linux in general).Any chance someone could write/share a script or applet for switching USB modes, would be a bit quicker and more practical when you're on the move than having to open up Xterm every time you want to switch modes and plug in a keyboard or USB key ?
