I'm having a problem installing a driver for my Silabs USB to UART bridge.
I download my driver from here: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
I'm running Ubuntu 12.04 32bit Kernel Linux 3.5.0-27-generic
The instructions say that make (your cp2010x driver)
cp cp2010x.ko to /libmodules/<kernel>/kernel/driver/usb/serial
insmod /libmodules/<kernel>/kernel/driver/usb/serial/usbserial.ko
insmod xp2010x.ko
However, I get this error when I try to call make:
root@grace:/home/admin/Desktop/usb# make
make -C /lib/modules/3.5.0-27-generic/build M=/home/admin/Desktop/usb modules
make[1]: Entering directory `/usr/src/linux-headers-3.5.0-27-generic'

I am new to Linux. I've Googled the error a lot but I can't find any answers that works.
According to this forum post, those drivers have actually been a part of the kernel since March 2009. You can see the file at drivers/usb/serial/cp210x.c (here is a link to the file in the latest stable version of the kernel).
