Hi Marius,
thanks für your quick response. Yes I tried MPROG, but this fails
too..."No Chip found"
.
The returncode from ftdi_usb_open() is "-8: get product description failed"
The lsusb -v command returns:

Does anybody know how to access the eeprom again under ubuntu 8.04? I
modified the vendor and product id in example.conf for ftdi-eeprom,
but the chip is not found.
I assume that by "non-accessible", you mean that ftdi_usb_open() with
your 0000/0000 IDs returns < 0.
If so, which error number does it return? (see ftdi_usb_open_desc()
for docs)
I also assume that you already tried MProg under Windows and that this
one also fails.
Then I would try the following:
o Check a usb device prober on your system to see that the device is
enumerated by the OS
o Look at ftdi_usb_open_desc()
- Debug this function and see if your device is enumerated by libusb
- If the enumeration works and your device IDs match, look at
exactly what fails in that function and
see if the problem is obvious (or report your findings here).
Good luck ;)
