View Full Version : [ubuntu] compiling the kernel for USB device drive in Ubuntu 11.04

August 26th, 2011, 08:30 AM
I have tried to connecet a new USB device (ez430) to ubuntu11.04 which will create virtual serail port /dev/ttyACM0 . using this I can access the data .

I could see the virtual port has been up after I connected the device , but I cant write/read anything from the port . it gives input/output error .

I tried to contact USB device vendor for this problem, they said I need to rebuild the kernal with some settings:
following is the suggestion gave by USB vendor:
My guess is that it's a kernel configuration issue. The steps for compiling the kernel can be found here: http://www.cyberciti.biz/tips/compiling-linux-kernel-26.html
In the kernel config (step 2), make sure these are enabled:
Device Drivers --->
USB support
<M> USB Modem (CDC ACM) support
<M> USB Serial Converter support --->
<M> USB TI 3410/5052 Serial Driver

I dont want to rebuild the kernal , is there any other way to put this to the existing kernal with out buliding the kernal again ..?
if so , pls help with that .
