Thanks! You are right.
But I still have one question:
When I plugin a compact flash card to the USB adaptor, the Slax will create
sdb,sdb1,sdb2,sdb5,sdb6. Five files in /dev directory. (The compact flash has
Linux OS which is used to boot system and total size is 64M)
And I write a Java program to read these files byte by byte, the total size
(sdb1+sdb2+sdb5+sdb6) is bigger than 64M.
That means some files are created duplicated?
I really don't know how the mounting process in Slax. And I don't know the
first(start) byte physical location(in sdb1 or sdb6?).
Any one can give me some information how the sdb1 created?
Regard

Subject: Re: [javax-usb-devel] Read USB device
Unless you want to implement the entire USB mass storage layer, you
don't want to use javax.usb to read your block device. You should
instead just use normal file I/O, like a FileReader or some other
reader. For example:
FileReader reader = new FileReader(new File("/dev/sdb1"));
reader.read(buffer, offset, length);
