Lexar Jumpdrive Firefly recall

USB thumb drives seem fairly simple, nothing hazardous…. but Lexar has recalled several models of the Firefly series as well as the JumpDrive Secure II, 1GB model. The affected Firefly sizes are… 256MB, 512MB, 1GB and 2GB. They apparently have a “risk of burns to consumers and property damage.” I would assume the risk is ONLY when they’re plugged in to a USB port. I wonder if it has to do with the circuit for the LED light. USB provides 5 volts power and LED’s can be quite particular about getting the exact voltage needed. In a LED circuit you usually have a resistor to bleed off the un-necessary voltage. Once I built a light with about 18 white LED’s and I ran into a “design failure” in my first attempt (didn’t take into account the wattage rating for the LED.) and so the first mockup had a smoking resistor.

Of course, I don’t know what the problem is here, it could be a miswiring – or something that could easily short. Who knows, but don’t play around with it. If you have an affected model – look into what you need to do for a replacement. The direct link to Lexar’s announcement on this is here.
