Model B Hardware Revisions and USB Power limits Hardware Revision 1.0 There is a Wiki section about this issue which is worth a read. If the Raspberry Pi's supply voltage falls below a certain value (anecdotally stated as around 4.75 V), or it begins to fluctuate, your setup may become unstable.

(B) - Relates to model B production board.

(A) - Relates to model A production board.
