You have to edit the ftdi_sio driver and recompile it. A hint:
cd /usr/src apt-get source linux-image-$(uname -r) cd linux-2.6.24 Now you have to edit the drivers/usb/serial/ftdi_sio.c/h files (add your VID PID combination). make oldconfig make drivers/usb/serial/ftdi_sio.ko rmmod ftdi_sio cp -b drivers/usb/serial/ftdi_sio.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ 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). -- [Hardy] FTDI based USB to Serial Converter not recognized https://bugs.launchpad.net/bugs/251952 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
