1279237 2012-06-02 06:00:00 Why would a manufacturer (in this case Panasonic) say in their product manual only to use the USB cable that came with the device? :illogical pcuser42 (130)
1279238 2012-06-02 06:05:00 Maybe they don't want people saying their device is faulty just because they bought a cheap USB cable off the net. Just a thought PC builder (15482)
1279239 2012-06-02 06:08:00 Or they only want people to buy panasonic USb cables Nick G (16709)

1279241 2012-06-02 10:18:00 If it's a standard cable then it's Just a case of arse covering as already suggested, in some cases though manufacturers use a non-standard plug on one end.

On a completely unrelated note, I will never give in and use the american "ass", it will always be spelt "arse" assuming the forum allows that to be displayed.

I can think of three possible reasons:

1) Their cable has a ferrite bead attached for EMI reduction, if you were to use one without it, the product may not operate correctly or it may cause the PC it's plugged into to operate incorrectly.

EDIT: (May also be that you need a cable built for USB 2.0 etc, an older cable with USB 1.x in mind or a cheap crap cable may not be of good enough construction for decent signal integrity either)

2) Their cable might have a non-standard pinout, and using a standard cable may cause damage to device and host. (unlikely to be the case though)

3) They want to try and convince you that if the cable breaks you have to buy a new one from them for a ridiculous price.


I would put my money on 3 and maybe 1.

This cable does, so perhaps that's a reasonable explanation.

I would hope if they use non-standard pinouts then they also use a non-standard connector :p

Unfortunately that's not always the case... fortunately it's not often.
