I am attempting to attach a "Currentcost" device to the USB port of my sheeva plug but I cannot get it to talk. The Currentcost has a Prolific PL2303x serial to USB conversion chip. I know block devices work correctly since I can attach USB drives or Pen drives. I am detecting the Prolific chip correctly and I have the latest debian release as shown below.
Bus 001 Device 012: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@debian:~# uname -a
Linux debian 2.6.33 #2 PREEMPT Tue Mar 2 14:27:17 MST 2010 armv5tel GNU/Linux root@debian:~#
When I connect to USB, the device /dev/usbdev1.2 appears but I do not get a device /dev/ttyUSB0 which is what I would expect. Has anyone connected to the Prolific device through USB?
I have read somewhere that the PL2303 driver is compiled into the kernel. Can someone confirm this is true? If not, how should I proceed? As far as I can see there is no driver for Linux on the Prolific site.
I have been looking at modprobe and loading a driver module but without a driver that is no good.
