Long answer: I don't see this getting fixed overnight, given the complexity of the USB drivers, and it's beyond my ken, so unless someone is willing to step up and fix it, it will lag. I have a USB2 drive enclosure. I have tried both an ATAPI CDRW drive and a recent Seagate drive in it. Under ehci, lots of failures, and indeed the occasional panic. Under uhci, it's rock solid, but slow and restricted to USB1.1 speeds. Workaround: The only way to disable ehci is to neither compile it nor load it into the kernel right now (for 4.x, 5.x and CURRENT).
