Intel has released a product-change notification (PCN) to its partners that informs them about the new C2 stepping planed for the upcoming 8-series Lynx Point chipset based motherboards. The stepping should fix the USB 3.0 issue that will apparently plague the C1 stepping until July.


The earlier reported issue is more of an annoyance rather than an issue and manifest itself when system is waking up from sleep states and failing to reinitialize devices plugged in the USB 3.0 port requiring users to replug them and lose all unsaved data. In order to fix the issue, Intel has to do a hardware revision and has now announced C2 stepping version from Z87, H87, Q85, Q87, C222, C224, C226, QM87, HM87 and the HM86 chipsets.


The bad side of the story is that first samples of the new C2 stepping are expected in July and Intel has not given up on launching Haswell in June but with C1 stepping motherboards that will have that issue. Motherboard manufacturers will switch to C2 stepping sometime after July 2013 so in case you are not keen on getting the Haswell as soon as it launches you might want to wait for a few months.
