This problem may have been fixed by the most recent mainline kernel releases 2.6.38.1 and 2.6.37.5.
In the change log:
Alan Stern (2): USB: serial drivers need to use larger bulk-in buffers USB: move usbcore away from hcd->state
I did my test with 2.6.38.1 kernel on Maverick and the copying speed appeared improved. Some one may want to do more test and update the bug report.
