The reason for not having "device ehci" in GENERIC was something about missing support for USB2.0 HUBs. When one has got a USB2.0 HUB and "device ehci" in the kernel config file, then the HUB will probe as USB2.0, which is not supported for HUBs, else USB1.x. So maybe your problem is a reason to push support for USB2.0 HUBs? Yours --HPS
