Yes: Old ports are suddenly playing nice. I moved two devices to the new controller, one disk and one host (Dell LCD screen) to which I again added two disks. In addition, one disk is connected to an old port (on the motherboard.)
All work with ehci_hcd at full speed. (About 20-30 MB/s for these disks.) I have stressed the system by copying large amounts (hundreds of GB) between all disks at the same time, and it all work. Note that before, all these disks, also those connected via the LCD monitor, was not operated properly by the kernel module. And as I said, even when the disks were turned off, these "reset errors" were written to the logs, from time to time. Note that there are lots of chips & devices in my system, Seagate, Maxtor and WD disks, USB hosts with Intel ICH9 and Via chips. The new PCI-card that "solved" the problem has a Via-chip. So, I guess I can confirm your last statement, even though I have not tried different permutations of disks/ports. The first permutation worked, which I take as a strong indication that all others also will, since it was not picked specially.
