If you don't want to read all that, here's a summary from Wikipedia:
Originally the on-board USB ports were designed for USB devices
using one "unit load" (100 mA) of current. Devices using more than
100 mA were incompatible with the Raspberry Pi, and for them a
self-powered USB hub was required. However, due to user feedback,
the RPF, at the end of August 2012, decided to remove the USB
polyfuses which largely caused this behaviour. However, the maximum
current that can be delivered to a USB port on these modified boards
is still limited by the capabilities of the power supply used, and
the 1.1 A main polyfuse. Also a disadvantage of the current way the
modification is done is that its no longer possible to hot-plug USB
devices directly into the PI, when hotplugging is necessary it can
be done in a hub.
