Early Haswell chips contain minor USB flaw, new stepping inbound

Early Haswell devices will use the flawed chips despite problem

Following some earlier reports, Intel has confirmed a bug exists in the silicon of its next-generation Core processor dubbed "Haswell." The bug can cause USB 3.0 devices to vanish after entering a low power state, with the device generally having to be disconnected and reconnected for the file structure to reappear.

Confirming the issue, Intel released a statement reaffirming the launch proceeding as planned. The company said that "4th gen Core is on track for a midyear launch. Intel issued a PCN (Product Change Notification) documenting a chipset USB errata and stating that chipsets with the errata will be in production during the initial ramp. But Intel has confirmed that there is no chance of data loss or corruption. This issue has only been observed with a small subset of USB SuperSpeed thumb drives and does not affect other USB peripherals. We take all customer issues seriously and should any customer have a question or concern they can always contact Intel customer support."

A new revision of the chip will be sent to manufacturers starting April 19, with the final version of the chip available July 15. PC manufacturers have had the chip in hand for manufacturing for the last two months, with the first iterations of products released at launch likely to have the chipset with the flaw.

The Haswell chips will operate using as little as 10-watts of power, and was demonstrated on-stage during the Linktext2013 Consumer Electronics Show in the form of an Ultrabook with a 13-hour battery life and a new detachable-keyboard reference design codenamed "North Cape." Haswell is expected to deliver double the graphical processing performance of the Intel HD4000 incorporated in the Ivy Bridge chips when it debuts in PC notebooks and likely in Apple MacBooks as weill during the second half of this year.

    Why

    Why do companies do this......they know of a bug, fix it then release! It will come back to bite them later. Probably hurt them up front as well with backlogs, but I'd rather see a bug free release instead!
