If there is no reaction, then the USB flash is dead. It could be that
there is a break in where the connector meets the PCB, inside the flash
packaging.

You should also test, with a known to be working USB device. That
will demonstrate how the program is supposed to work, and also prove
there isn't a problem with the USB ports on the computer you are
using for this testing.

I also use a couple Linux LiveCD distributions, for hardware testing.
Knoppix (knopper.net) and Ubuntu (ubuntu.com), can be booted from
their respective CDs, without installing any software on the hard
drive. Using programs like dmesg, lspci, and lsusb in Linux, you
can list/enumerate the hardware that the OS can "see". But UVCView
should be doing the same thing, with a much smaller investment
in time and effort. Those Linux distributions, are a 700MB download.
Any time I need to prove "it's a hardware problem", I boot one of
the Linux CDs, and see if the symptoms look the same. For example,
my first computer had a video (AGP) problem, and the symptoms
existed in both Windows and Linux.
