[C.CC USERS] Almost there with Ubuntu

[Dennis Meade]

Omer,

Thanks for your help.

I did as you suggested and added a filter for the USB in the VirtualBox 
settings. The VM says it's active and lists it as FTDI FT232R UART 
(0600), but Ubuntu 9.10 doesn't see it..

lsusb is the same as before:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

fdisk - l is:

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         993     7976241   83  Linux
/dev/sda2             994        1044      409657+   5  Extended
/dev/sda5             994        1044      409626   82  Linux swap / Solaris

I've looked at the Ubuntu documentation about mounting a USB port, but 
didn't find anything that would seem to help. I did find the VirtualBox 
USB documentation that said to do exactly as you suggested, BTW.

I'll keep trying, but would still be very grateful for any pointers.
