I mount my USB pend rive asynchronously, Copy the file, and umount it.. Wait until it umounts, then pull it off the drive. I get about 100 KBytes per sec on a USB 1.1 version of my "pen drive". I usually move about 20 to 60 mega bytes per second. This only takes me a couple of minutes.
The maximun transfer speed for usb 1 is 12MBit/s, ie, 1.5 Mbyte/s, not counting overheads. If you get 20..60 Mb/s, it is the buffer speed you are measuring, not the real device speed. Also, internally, the flash memory can attain a maximun speed of 100Mbit/s, ie, 12Mb/s - it is not possible to go higher than that.
