cyrus88 said:although this device sound like quite normal for our daily life(pen drive to common). but i think it involve too many thing, from OS, FAT32,NTFS,FAT,USB,...bla bla bla....many study and research needed
btw do you mind to give me yr msn? coz i doing same project, maybe we can share some information or idea.
thx.
cyrus88 said:but if i wan my device provide a simple UI for file selection, i need os right? because i have to display the file to LCD and let use select. am i right?
itaig said:I have seen some devices which allows a micro-controller to access a USB device via a micro-controllers SPI port. Even takes care of the file system. The devices are made by FTDI and the device is called Vinculum VNC1L. These are actually a microcontroller but the site has firmware that can be downloaded to perform the above function. Certainly much easier than trying to develop a USB host yourself.
doraemon said:Hello!
No, you don't need an OS to display a file list.
Just access to the raw blocks can make it.
Beside this, the original question was about to copy the full contents of a
USB stick, not to select files. So in this case, you can do it with a very trivial
system.

:|FvM said:When discussing low-level data copy between USB memory devices, it's meaningful to think about data throughput, too. With todays xGByte devices, any solution below High Speed USB may be regarded inacceptable.
If you target to high speed USB copy, you won't most likely find a more economic solution than the MCopy device shown in the above link. Basically it's an ARM9/linux system with dedicated high speed USB host controller - and a state-of-the art mobile LCD display. See the hardware platform specification
The device is a USB host controller with a built in CPU for handling the USB protocol and depending on the firmware loaded it can handle the file system as well. Outside of the chip you can consider it just as an intelligent USB host controller. All you have to worry about is talking to the device to get a directory listing and reading/writing files, the VNC1L does the restcyruss88 wrote:
ya, this device is cool for this project, but still many thing have to concern.
btw one thing i wan to make sure is VNC1L is a USB controller or Microcontroller?
eltonjohn said:what is the use for something like this?
mtaher13 said:i found out today that this gadget is made by a company named UNICON, and the gadget is named "MCOPY" and its available for 109.9$... still any ideas of making something like that visit this link **broken link removed**
raven_heart747 said:hi guys.. just wana inquire on how to program this microcontroller.. does it need its own burner? if so, where can i get the burner? thanks guys..
PICUSB said:HELLO. even i am doing the same project. could anyone tell me that is it necessary to write device descriptors while dealing with at90usb128.what actually a firmware in this case does? could anyone guide me?????
