Here's one more data point.  I added a USB2.0 PCI card to the desktop 
machine, and repeated the above steps.  The "dd" command worked.  I didn't 
change the kernel or anything else (it has all USB controller types 
built-in).


Here's the info for the USB2.0 PCI card:
00:0a.1 USB Controller: NEC Corporation USB (rev 41) (prog-if 10 [OHCI])
        Subsystem: Unknown device 1735:0035
        Flags: bus master, medium devsel, latency 32, IRQ 12
        Memory at ee001000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [40] Power Management version 2

00:0a.2 USB Controller: NEC Corporation USB 2.0 (rev 02) (prog-if 20 
[EHCI])
        Subsystem: Unknown device 1735:00e0
        Flags: bus master, medium devsel, latency 32, IRQ 11
        Memory at ee002000 (32-bit, non-prefetchable) [size=256]
        Capabilities: [40] Power Management version 2
