Will Haswell MBP have the USB 3.0 bug that has been reported?

It's quite a deal-breaker for a Pro laptop. They will wait until the issues with the chipset are fixed. It is likely that Intel will bring out a second batch after the initial release.

The issue is with the chipset, not the CPU.

Unlikely. Development versions use probably the C1 stepping.

Description of Change to the Customer:
Intel is initiating a C1 to C2 stepping conversion for the Intel® 8 Series/C220 Series where products will undergo the following changes:
• Metal layers change from C1 to C2 to fix USB SuperSpeed device remuneration erratum.
• C1 stepping package is pin compatible with C2 stepping package.
• Revision ID will change from 04h to 05h.
• Compatibility revision ID will remain at 04h for Intel® Stable Image Platform Program
(Intel® SIPP).
• New S-specs and MM numbers for the converting products.

The latest reports seem to suggest that the bug isn't as big a deal as a lot of people originally thought. Basically, with *some* thumb drives, if you leave them plugged in when you sleep the computer they won't be recognized on wake and you have to reconnect them.

So:

  • Non-crashing
  • No data loss
  • Only thumb drives
  • Not all thumb drives
  • Only for a very specific use case (leaving them plugged in during sleep)
  • Workarounds exist (unplugging / replugging drive upon wake)
  • EVERYTHING else USB3 reportedly works fine

This is a very specific use case that most people will very rarely run into. If you're someone who frequently sleeps their computer with thumb drives plugged in, this might not be something you want to buy. For the rest of us, it's not a big deal.

Yes, but isn't the fix due at the end of July or something? So the earliest we could expect a refreshed rMBP would probably be August/September, unless Apple decides to ship with the flaw.

Just SOME thumb drives? I was under the impression that it was devices plugged into the USB, I.E. Printers, Ext drives etc. I can honestly say I have never left a thumb drive in while sleeping. As far as I can remember.

Well, no, im not positive. The cnet article seems less specific than the one that was on the MR front page this morning, which seems to indicate only some thumb drives: http://www.slashgear.com/intel-begins-shipping-its-next-gen-haswell-chip-08276917/

Intel has confirmed that the intial batch of Haswell chips have a bug that can affect USB 3.0 ports. Intel says that your files will be safe from data loss or corruption, but after waking up your computer from standby mode, you may need to re-plug your USB device into the socket. So far the issue seems isolated to a small amount of “USB SuperSpeed thumb drives”.

I can almost guarantee they will not. When the SB bug was out, all of Apple's chips were stepping 2 or 3 so they had the CPUs with the fix.

-P

So...you're hoping it will have the bug? Huh??

C'mon.. WHO doesn't love BUGS.. Gives us something non-sensible to discuss here about products that have not come to market yet, and I must thereby assume that people here think the Designers are 'almost oblivious and uncaring' as to what sludge they expel to the masses .. :D

But that probably means a delay, right?

Perhaps....but I think the delay will be very minor. Everybody thought the SB MBPs would be delayed or the early ones would have the bug. The MBPs shipped fairly early without the SB bug.

Agreed. Sandy Bridge had a problem with some of the SATA connections failing over time, IIRC. Intel identified the bug a couple of months before the product was released, and spent about one billion dollars ensuring that any company that requested fixed boards had them in time for them to release their products on schedule.

Also, IIRC, the bug was such that Apple could have used the flawed boards, with no harm done, as it was a problem with the extra SATA 2 connections that the MBPs don't use anyway. But they still got the fixed boards, and were released without delay.

I guess the last resort would be that Apple just uses a third party USB 3 board, instead of a native one, like they do now.

This situation seems different. Intel has stated that fixed chipsets would be available between Jul. 15th and 31st. Which to me, sounds like Apple won't be releasing updated Macs until at least August/September.

Hard to tell. I would however expect Apple to release the new models around the same time as other companies.

Assuming Apple actually gets the new chipsets between the dates you specified, I wouldn't be surprised if Apple actually releases stuff around 2 weeks after they get them, i.e. early/mid August. They should have everything else ready by then, and just have to shove 'em together, and ship 'em out quick smart. :D

Possibly with a slightly squishy shipping time.
 
Intel already said that the problem was solved on 1-2 april. So no device will have the issue. Because i think the production will begin late this month, so no.
