I'm seeing what appears to be the same problem on 6.1:

The USB device is a Vosonic VP6230 (another HDD + card reader thing):

USB 1.0 stuff (a printer, Ethernet adapter and various other umass devices)
seem to work fine. I get the symptoms described by Gerrit when reading
from da3 (the HDD part of the Vosonic device) - a few MB of data is
transferred at reasonable speed, then the transfer hangs for a few
minutes. Rinse and repeat until done. The data appears to transfer just
fine and I can unmount the device successfully when done. I've seen what I
think was the same behaviour with another no-name external HDD box attached
to the same machine. Haven't tried any of the suggested workarounds yet,
and probably can't on this machine as it's also my firewall and router :)
I might have another box around with a VIA EHCI controller that I can test
on, will see what I can do.
Cheers,
Scott
