Message Text: Intel confirmed a USB bug in its next-generation "Haswell" chipset, which is set to be released this summer.

The bug can cause USB (Universal Serial Bus) 3.0 devices to disappear after entering standby. In some cases, removable devices have to be reconnected again.

The bug was confirmed in a Product Change Notification bulletin the company released. The notificatios says that the bug is related to the current Lynx Point 8-series and C220 chipsets for Haswell. Affected chipsets include the Q87, Q85, H87, Z87, B85 (desktop chipsets), C222, C224, C226 (workstation/server chipsets), QM87, HM87, and HM86 (mobile chipsets).

The Product Change Notification continues saying that a new "stepping" -- a version of the chipset with the fix -- will be sent as samples to customers starting April 19. The final version of the fixed chipset will be available starting July 15.

Haswell is the next-generation mainstream Intel processor that will power ultrabooks and a variety of hybrids that straddle tablet and laptop designs. It is shipping to PC makers now.
