Volume production u disk most easily make two mistakes

A lot of friends in the use of U disk startup like the volume of U disk production into CD-ROM format, but in the production process will always appear in this or that kind of problem, now say the most easy to make two mistakes.

One, u disk chip model mistaken.

Second, the computer USB socket current, voltage is insufficient. The first reason everybody understands well, the second reason everybody does not understand, we take a closer look. At the beginning, in the process of experimenting on 14 computers, we found a strange phenomenon, the same U disk and production software (mass production tool software), some computer production can be successful, some can not succeed, and even the use of its chip-specific production software, even the correct capacity of U disk can not be recognized ( For example, to recognize 4GB as 2GB, or 4GB to 8GB), so we should pay more attention to this aspect.
