I had some trouble loading the FTDI serial module that allows me to access the console of the SheevaPlug. Thanks to Matt, I found out that in the recent past the vendor and product codes that the kernel module uses have changed and therefore when the module loads it can’t find the hardware that is already plugged into my USB port and, therefore, no /dev/ttyUSBx devices show up.
The vendor and product codes used to be vendor=0x9e88 product=0x9e8f, but now I load the ftdi_sio module as follows:
# modprobe ftdi_sio vendor=0x1c0c product=0x0102
and the ttyUSBx devices show up happily thereafter. You can find the new codes by doing a:
# lsusb
which should show a line that looks like:
Bus 002 Device 023: ID 1c0c:0102
enjoy.
