Fast 2.0 USB thumb;  it has been in use (as a big diskette) for a year
(literally), then died.  Resetting controller didn't help.  It really
was fast -- provided ~20MB/s write speed.

SD card has been left without usage for a year then taken for a job (as
a big diskette).  After half year it started requiring massage for being
detected (plug-unplug cycles).  Then came the last time -- now it's 1GB
instead of 16GB.

(not mine) I took a challenge to heavy lift whatever possible from an
USB thumb.  When certain blocks had been accessed the thumb reset itself
-- I've made a script that used 'udevadm monitor' for wakeup detection
and lifted "whatever possible".  According to owner's report the thumb
was in use for a month (literally).

Two IRDA dongles -- never worked;  what's probably OK, they needed weird
setup.  When, after a pause (about a year) I'd made a second attempt
each just ceased to wakeup.

CDMA modem worked for a year (I wouldn't say flawlessly) developed a
requirement -- pppd had to be in within 10min, otherwise negotitions
would take forever.

UMTS modem worked for 4year (literally, it died 4y+2d after first
plug-in) (I wouldn't say flawlessly), then ZeroCD ceased to work with
block device errors present instead.

And not to mention USB closure!  When I'd tried it first time I'd pluged
in by-instructions and unplugged by-logic (reverse-in).  Then The Second
Move has(sic!) come -- I've unplugged by-instructions.  Putting a long
story short -- I've burned down one USB-host.  That was spectacular, no
flames though.

It has been put aside, then squeeze had come.  All DVD-images came out
with errors.  I've collected some stats -- no clear pattern.  So I've
made a script that lifted those 16 DVD-images.  It took some time
though.

I don't mention two UMTS modems with 'normal-termination-by-ncp' disease
-- that's on ISP side and I have no options.

I ain't no heavy user -- I have a couple of thumbs, developing a
collection of SD-cards, some USB-devices and such.  I've never faced
problems with cameras and recorders (whenever I've faced those).
