Trying to figure out how to load the Prolific USB-serial driver on Overo Air. Here’s what I have done to try and load the pl2303 module:

 

opkg update (w/o doing this step first, installing the pl2303 module fails)

opkg install kernel-module-pl2303

 

After I did that, the Prolific module was located at:

/lib/modules/2.6.32/kernel/drivers/usb/serial

 

However, Prolific devices are still not being mounted at /dev/ttyUSBX. If I try to manually load the module using:

 

modprobe pl2303

 

then I get the message:

 

FATAL: Module pl2303 not found.

 

Using insmod doesn’t work either:

 

cd /lib/modules/2.6.32/kernel/drivers/usb/serial

insmod pl2303.ko

 

Get the error message:

insmod: error inserting 'pl2303.ko': -1 Invalid module format

 

I’m not sure how to get the kernel to recognize this new module. I think part of the problem is that in /lib/modules I now have 2 directories: 2.6.30-omap1 and 2.6.32, where the 2.6.32 branch only contains the pl2303 module (and nothing else).

 

Ideas?

 

Thanks,

 

John
