said by Redfeather20 :I just wanted to know whether my computer should be turned completely on and booted all the way up before I insert the device into my computer's USB port . . . or if it would hurt anything to insert the device into my computer before I power it up.
Generally I connect USB modems *after* the system is up and running... but it shouldn't hurt if you do it before.
Some of the USB modems have the driver software built in that gets presented as a virtual cd rom drive... on a couple of my laptops they would never boot (just sit at a black screen) when they came in contact with that virtual cd rom drive... while other laptops had no issues (due to the bios ignoring USB devices for boot drives).
Looking at the information at the sprint site they only warn not to insert it before installing the driver software, which won't harm the device so much as get windows confused about the drivers.
