Does anyone has seen a Oscilloscope home project on the web that can be connected by means of usb 2.0 ?
Thanks in advance.

you could use slave FIFOs with Auto-IN mode of FX2. You don't need a special driver for FX2. There is a example generic driver comes with it. You just need to download code with EEPROM or from usb and use windows API to communicate over usb driver. See EZ-m@nager's source code...
MFC is not a problem for this.
there are two projects with FX2

imxo, dsp + fpga, is truly standard decision of this problem.
Why You prefer SRAM version then DSP with SDRAM External Memory Interface +SDRAM module decision?
Also, Look at Agilent HFBR fiber optics product for PC interface. For example, HFBR-RUD100, HFBR X5XX

We have a bunch of those scopes at work. They do the job, but they're not great. If you were thinking of using the usb connection, forget about it. It's as useless as they come!
For maybe an extra 10% you can get an Agilent or a Tektronic which offers the same functionality, but with improved user interface, better usb / PC connectivity,

usb control is the simple part of your project. For the other, it depends on the specification. If you regard acquiring of kHz audio
signals as "dso", it can be simple too. Several 10 MS/s, as achieved by typical usb oscilloscope black boxes, is already demanding.
It requires special hardware and a profound analog and digital electronics (...)

There are really two answers to your question, one hardware and one software.
Hardware: PCMCIA and usb connectors are designed to make power connections on insertion before signals and break power after signals on removal. This provides a relatively safe "hot plug". The other bus connectors (ISA, PCI, IDE/ATA) are not designed with this feature.
