Re: [Ftdi-usb-sio-devel] Linux thin client -> usb badge reader

[Thys M. <st...@gm...>]

you can un-compres the squashfs image, add the module (compiled for
your kernel version) and recompres. As long as you have a reasonably
close dev environment on another machine you should be able to pull it
off.
In short, I would:
- get a precompiled debian kernel of the same version than your image,
-  extract the ftdi module from it
- copy the image from the SD card to disk
- uncompress
- add the module
- fiddle with /etc/bashrc or similar in the image to load the module
with the VendorID/ProductID as previously noted
- squash
- copy the image back to the card
- test
