Low umass performance with USB 2.0 ports

Tue Aug 30 09:28:21 GMT 2005

  Good day.
 I am observing very low umass performance: when I am trying to move a large
file from/to my USB 2.0 flash that is plugged into the USB 2.0 port: transfer
starts fine at 3.5 Mb/sec, but after some 20 Mbytes it hangs and the process
(dd) stay in the wdrain state. The activity LED on the flash shows no activity.
Operations do continue, but very slow and the most time of the copying process
spends in the wdrain state. All attempts to invoke `sync` or to see the
file state via `ls` are hanging until `dd` leaves the wdrain state.
 It does not matter what flash is used: I tried Apacer and the Kingmax ones --
the result is the same.
 If I plug the flash into the USB 1.1 port and trying to move some data -- it
works fine, no hangs. Speed is 500 Kb/sec.
 Seems like others do have this problem:

 USB 2.0 controller is Promise PCI (NEC chipset), USB 1.1 chipset is onboard
VIA.
 My dmesg output is:
