[Paparazzi-devel] anyone else having problem with ftdi FT2232H on oneiric?

[Felix Ruess]

Hi all,

is anyone else having problems with the FTDI FT2232H on oneiric?

I often don't get anything on the tty for the FLOSS-JTAG serial connection.

It works right after a reboot, but after unplugging, replugging twice I don't get anything anymore.

It might be coincidence that it doesn't work after replugging twice, but it seems to work if I get a device number lower than 8.

It is definitely not a paparazzi issue, I can't even get anything with cat or minicom...

It also always works on my netbook (still on natty). And my xbee with FT232RL usb<->serial converter runs fine (on natty and oneiric).

Udev loads the driver, creates the devices (and custom symlinks I added) just fine.

So it probably is issue with the driver... but unloading ftdi_sio doesn't help either.

It seems they fixed some FTDI issues in 3.0.0-15.25: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897514

But it didn't solve my issues...

Tested kernel versions: 3.0.0-15-generic and 3.0.0-16-generic on 64bit

Did anyone have the same problem? Any ideas?

Cheers, Felix
