USB1 cable vs USB2 cable

Hello,

I have a few USB cables that I have not used in a while. I do not know if
they are USB 1 or USB 2 cables. Is there an easy way to tell? Thanks.

Nope, technically there is no difference with the cable standard wise.

In practice there are some cheap cables that dont do USB2 well.

Usb 2 cables are more likely to be gold plated. But it's not a rule or
anything.

'Bout the only way to know if a cable isn't up to doing usb2 is to
test throughput on known good hardware. A lot of work, though.

No unless it's marked on it, but a cable sold as USB1 long
ago may work fine at USB2 speeds. In general a better USB2
cable will have lower gauge (thicker) wire, which generally
means a thicker bundle of cable, it just looks thicker in
total too though it could only have a thicker
insulation/abrasion covering instead.

Try the cable, if it works you're done.

The only difference is USB2 requires a shielded cable, it was optional
for USB1.

Haven't read the specs have you. For USB1 cables the shielding was
optional. www.usb.org is where I found the info a year or so ago.

Ignore Speed, or better plonk it. It is a troll, and "wrong" is
50% of its sparse vocabulary. Replying just serves to encourage
it.

and 95% of the time wrong was right,(despite the delivery) and so it is in
this case. All USB cables were and are shielded. In some extreme cases like
pigtails(4in or less) for USB drives or MP3 players they were 'barely'
shielded and really cheap 6 ft's had scantily shielded cable, like those
that came with some handhelds and other peripherals. however it was never a
lack of shielding it was a quality issue.
