The USB 2.0 Promoters have voted to adopt an addendum to the USB 2.0 Specification designated "Low Voltage Inter-Chip Supplement to the USB 2.0 Specification" ("Spec Supplement", posted with the USB 2.0 spec above) and to provide USB 2.0 Adopters the option of extending their Adopter Agreement to address this new Spec Supplement (the Spec Supplement exceeds the scope of your original USB 2.0 Adopters Agreement, which is specific to the USB 2.0 Specification

supply provided by that connection. However, some flash drives, especially high-speed drives, may require more power than the limited amount provided by a bus-powered USB hub, such as those built into some computer keyboards or monitors. These drives will not work unless plugged directly into a host controller (i.e., the ports found on the computer itself) or a self-powered hub
more functionality than being simple data repositories. By presenting themselves as simple datastores, these devices can leverage the high degree of support for the USB mass-storage device class in current operating systems' USB driver stacks and allow easy read and write access to their internal memories. The downside of doing so is that it prevents the device from easily presenting its actual functional behavior across the USB interface too. For example, the makers of a digital still camera single-level NOR flash cell in its default state is logically equivalent to a binary "1" value, because current will flow through the channel under application of an appropriate voltage to the control gate. A NOR flash cell can be programmed, or set to a binary "0" value, by the
greater storage densities and lower costs per bit than NOR flash; it also has up to ten times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable to replace program ROM, since most microprocessors and microcontrollers cannot directly execute programs stored in memory without random access; howeve
