Bug Description
Binary package hint: udev
FTDI chipset based USB to Serial converter does not create /dev/ttyUSB* device on Hardy 64-bit, kernel 2.6.24-19, udev 117-8.
/var/log/kern.log when plugging in the converter:
Jul 25 22:37:14 mars kernel: [ 1537.134393] usb 4-3: new full speed USB device using ohci_hcd and address 7
Jul 25 22:37:14 mars kernel: [ 1537.234553] usb 4-3: configuration #1 chosen from 1 choice
The output of lsusb command shows:
Bus 004 Device 008: ID 0403:e40b Future Technology Devices International, Ltd
There is no conflict with /etc/udev/
You have to edit the ftdi_sio driver and recompile it.
A hint:
cd /usr/src
apt-get source linux-image-$(uname -r)
cd linux-2.6.24
Now you have to edit the drivers/ usb/serial/ ftdi_sio. c/h files (add your VID PID combination).
make oldconfig usb/serial/ ftdi_sio. ko usb/serial/ ftdi_sio. ko /lib/modules/ $(uname -r)/kernel/ drivers/ usb/serial/
make drivers/
rmmod ftdi_sio
cp -b drivers/
modprobe ftdi_sio
You should create a patch and send it to the linux-usb mailinglist.
Your device (0403:e40b) won't work even with the latest Kernel (2.6.27-rc1).
