I need to install a driver for a CP2101 USB/Serial device. I read somewhere that it’s part of the kernel and was hoping I could download and automatically install it. I found this page:
Which gave me great hope, but I have absolutely no clue what it means or what to do with it.
Anyway, I was hoping someone could tell me how to install this driver. Very new to Linux and trying to avoid compiling if possible… lost in the woods very quickly.
If compiling is the answer, then I need help there too. I downloaded the Linux driver kit from Silicon Labs web site, followed the installation instructions, ran into an error and quickly bailed. The error is:
LD/cp210x-3.0.0 M=/var/tmp/silabs/rpmbuild/BUILD/cp210x-3.0.0 modules
make: *** /lib/modules/2.6.31.12-0.2-desktop/build: No such file or directory.
Which makes sense in that there isn’t a /lib/modules/2.6.31.12-0.2-desktop/build directory but didn’t help much with the driver install. I’ll include the full output and maybe someone can tell me what I’ve done wrong.
Thanks,
sr
