A few more details would be helpful, such as the dmesg log (with CONFIG_USB_DEBUG enabled). As it is, I don't see how that commit could cause this problem. It should not have resulted in any changes in behavior -- all it did was split up a driver that was one module into two modules. > This behavior was previously fixed with commit c618759. That commit affected the ohci-hcd driver, whereas this one affects ehci-hcd. They can't possibly be related.
