USB storage or USB cdrom ? 

If it's CDROM try ejecting it. ("eject /dev/srX" .. where X is the number
assigned to it, can be found in the output of dmesg after connecting the
device.)

It's not windows, that's how wireless networks work. The total
bandwidth/maxspeed is for the whole cell tower/antenna.. not per device.

If everyone in a cell starts accessing the net on their mobiles/usb devices,
speeds will rapidly drop to sub-dialup speeds.

usb_modeswitch only works on devices that it already knows of. If it doesn't
know of your particular USB vendor-id/device-id combo. It won't do anything.

The maintainer is pretty proactive in adding new devices though.. all he
requires is a dump from windows machine which will tell him the necessary
command to switch modes.
