It didn't actually catch fire but it could have!!


I plugged in a pair of video record glasses on my computer. I started smelling burnt plastic and luckily I unplugged it in time. The USB cord is melted. I have since plugged in different devices to test it with no issues.

Am I correct in assuming the device is defective? crappy made in China

is it for charging or copying data

i suggest using a stand alone charger and a flash card reader if it is removable

No external card it is a built in 8g I fully charged before I connected it to computer

I'm surprised the USB port didn't shut off. I've had a few issues with USB ports with dust in them and the computer noticed the power spikes of a short and shut the USB port off.

Anyway, sounds like a defective or poorly designed device.

It is hard to imagine enough power in a USB port (from a system, not a separate hub device) as the power is limited to 450mA total for that group of ports. Some are as weak as 250mA. That is not enough to even warm things up overmuch. I think power was back feeding from the devices battery somehow.

I've since plugged in other things to the USB with no issues.
The problem is either the cord or the video (spy) glasses.
