In the meantime I've tested 1 USB keyboard and 8 storage devices from
different vendors (2 card readers, 1 M-Systems uDOC, 5 thumb drives, 1
of which is an ancient USB 1.1 only). None worked.

Tried that with the 1st card reader which had made me write the original
message. Works with OHCI-only in Linux.

Cheers,
Jens
