I have just purchased a Startech ICUSB2321F which uses the FTDI FT232R chip with the intention of using it to connect an old APC BackUPS Pro with a serial port to a Netgear ReadyNAS Duo2 with a USB port. (The Netgear ReadyNAS Dashboard supports monitoring and display of UPS.)
On connecting the UPS to the NAS via the Startech cable the NAS recognises the USB device, as shown by the following output of "lsusb":
Bus 002 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
The NAS is running the Debian 6 Squeeze distribution with the following Linux version, as shown by the output of "uname -a"
I think I require a copy of ftdi_sio.ko and usbserial.ko drivers built for this version of Linux but have been unable to locate any on the internet. Note I have downloaded package linux-image-2.6.32-5-kirkwood_2.6.32-48squeeze6_armel.deb and extracted the files but when I do insmod using these I get the error:
insmod: error inserting 'ftdi_sio.ko': -1 Invalid module format
I do not think I can build the drivers from source on the NAS because it lacks a development environment and the repositories no longer appear to be available? If I try to do "apt-get install gcc" on my ReadyNAS I get errors of this form:
And does this NAS have the space on its OS partition to store the necessary development tools and Linux kernal headers assuming they are available? (what is the name of the OS partition for a space query?)
Any assistance or suggestions on these matters would be appreciated.
