Is everything ok with usb stack or at least with DD , because on my 2 laptops [EISystem and MSI] "DD" copies RAW raw data to USB with 20-27KB/S which is less than FDD copying speed..

Are you passing a size parameter to dd? i.e. bs=1024k ? By default dd uses 1kb chunks, which will indeed write quite slowly.
