Hi
I am using Linux Kernel 2.6.10 on an embedded PC104-Board with a Pentium
MMX. I need to connect a usb-device over a usb-hub to the PC104-Board.
Should look like this:
PC104<---->USB-Hub<---->USB-Device
I loaded all the drivers/modules I need, the pl2303 for the Prolific
Usb-Hub, and the evolution_rcm for the usb-device. And of course before the
usbcore, usbserial, ohci_hcd.
In the "dmesg" (see below) it looks like it load and connect to usb-devices,
but when I do "lsmod" the modules are not connected to something(See below).
Now when I try to start my programm written in C, completely working under a
2.4.29 kernel, it says that it is not able to open "/dev/usb/ttyUSB0".
The code of the C-programm:
filed = open("/dev/usb/ttyUSB0", O_RDWR | O_NOCTTY | O_NDELAY);
The device exist and look like this:
crw-rw---- 1 root root 188, 0 DATE ttyUSB0
When I connect a usbstorage-stick in the usb-hub, i can connect and look on
the usbstorage-stick. But I can´t work with the evolution_rcm...
Here is the "lsmod" output:

Can somebody help me with this?
Because I am not the best in Linux, and I need to learn many things, so give
me please some tips or hidden hints...
Thanks
