I dunno, that's why it's RFC. ;-) It's a timeout, so it *shouldn't* adversely affect other systems with well behaved usb chipsets. And boards will ill-tempered usb chipsets should work better. But I'm not familiar enough with the usb code to say that definitively. I could try doing a dreamplug-specific hack to make it work, but if there's no adverse affect to other systems, then this is a cleaner approach. thx, Jason. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
