FTDI Driver Breaks Hardware Again (eevblog.com)
janoc writes: It seems that the infamous FTDI driver that got famous by intentionally bricking counterfeit chips [NOTE: that driver was later removed] has got a new update that injects garbage data ('NON GENUINE DEVICE FOUND!') into the serial data. This was apparently going on for a while, but only now is the driver being pushed as an automatic update through Windows Update, thus many more people stand to be affected by this.
Let's hope that nobody dies in an industrial accident when a tech connects their cheap USB-to-serial cable to a piece of machinery and the controller misinterprets the garbage data. -
Debunking the Batteriser's Claims
An anonymous reader writes: Last week we discussed news about the "Batteriser," a small device that fits around a battery and extends its lifetime. Many of us were skeptical, particularly with the claim that it could extend battery life up to 8x. Now, David L. Jones at the EEVBlog explains exactly why the device won't be as good as its creators claim. The technology itself, he says, does actually work at extending battery life, and has existed for a long time. What this company seems to have done is just shrink it down to a more useful size. Unfortunately, their claims about when a battery stop working and how much energy is left don't really hold up. Batteroo, the company making the Batteriser, claims products stop working when a battery's voltage drops below 1.3v, but a simple test of common household gadgets finds that to be untrue. Further, the percentage of energy left in the battery after this cutoff can vary wildly. Sometimes it will be 80%, but most of the time it won't, and it's frequently 20% or lower for Alkaline batteries. Jones writes, "I'm genuinely baffled as to why Batteroo would need to resort to claims like 8 times life. This thing would still sell like hot cakes if they claimed realistic practical figures. 50% increase in your battery life? – great, countless people would still buy it at the super low price point it's at." -
FTDI Removes Driver From Windows Update That Bricked Cloned Chips
New submitter weilawei writes: Last night, FTDI, a Scottish manufacturer of USB-to-serial ICs, posted a response to the ongoing debacle over its allegedly intentional bricking of competitors' chips. In their statement, FTDI CEO Fred Dart said, "The recently release driver release has now been removed from Windows Update so that on-the-fly updating cannot occur. The driver is in the process of being updated and will be released next week. This will still uphold our stance against devices that are not genuine, but do so in a non-invasive way that means that there is no risk of end user's hardware being directly affected." This may have resulted from a discussion with Microsoft engineers about the implications of distributing potentially malicious driver software.
If you design hardware, what's your stance on this? Will you continue to integrate FTDI chips into your products? What alternatives are available to replace their functionality? -

FTDI Reportedly Bricking Devices Using Competitors' Chips.
janoc writes It seems that chipmaker FTDI has started an outright war on cloners of their popular USB bridge chips. At first the clones stopped working with the official drivers, and now they are being intentionally bricked, rendering the device useless. The problem? These chips are incredibly popular and used in many consumer products. Are you sure yours doesn't contain a counterfeit one before you plug it in? Hackaday says, "It’s very hard to tell the difference between the real and fake versions by looking at the package, but a look at the silicon reveals vast differences. The new driver for the FT232 exploits these differences, reprogramming it so it won’t work with existing drivers. It’s a bold strategy to cut down on silicon counterfeiters on the part of FTDI. A reasonable company would go after the manufacturers of fake chips, not the consumers who are most likely unaware they have a fake chip." Update: 10/24 02:53 GMT by S : In a series of Twitter posts, FTDI has admitted to doing this.
