I just started toying with a FTDI USB-Key on Linux, using libftdi and the
ftdi_eepropm utility. The kernel says it's an FT232RL chip on "dmesg".
Well, as a noob on this things, I tried to just replace the vendor, product and
serial strings, and had half success at that. The success was that the write
worked, but on the other hand it seems my settings broke the chip and it can't
be writen any more (although it works ok reading).
I attached a full dump of the broken device and a dump of a second device I have
for comparison.
It seems I wrote the eeprom for a "self powered" device instead of "bus powered"
one and the MaxPacketSize for the Input EP was zeroed.
The result is a device that can be read the same as before, but either erase or
write (although returning a success value) will just be ignored.
I tried the MProg program on windows to re-program the device but as soon as the
FTDI windows drivers load the system reboots. I still haven't tried the
FT_PROG utility because at the moment don't have a machine with .NET 2.0 installed.
Anyone know if/how I could fix this?
As I have a second device it's not that important the first one is recovered,
but I would like to know if I can recover from a second bad try.
Regards,
~Nuno Lucas
