[Q] Odys Xelio: usbserial.ko - Android Q&A, Help & Troubleshooting

Hi
I'm trying to compile usbserial.ko for the Odys Xelio (Allwinner A10 based Tablet). I'm usind this kernel sources: http://forum.xda-developers.com/showpost.php?p=25978796&postcount=121. According to a german android forum, these are the recommended sources.
I am able to compile usbserial.ko. The vermagic and the file signature are identical with the already existing modules.
Code:
vermagic: 3.0.8+ preempt mod_unload modversions ARMv7
file:
ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), not stripped
When I try to insmod the module i get this dmesg error:
Code:
<4>[22084.030000] usbserial: Unknown symbol usb_autopm_put_interface (err 0)
<4>[22084.050000] usbserial: Unknown symbol __stack_chk_guard (err 0)
<4>[22084.060000] usbserial: Unknown symbol kmem_cache_alloc_trace (err 0)
<4>[22084.080000] usbserial: Unknown symbol __stack_chk_fail (err 0)
<4>[22084.080000] usbserial: Unknown symbol __tracepoint_module_get (err 0)
<4>[22084.100000] usbserial: Unknown symbol usb_autopm_get_interface (err 0)
<4>[22084.110000] usbserial: Unknown symbol __gnu_mcount_nc (err 0)
(This errors show also up as warnings durring the module compilation)
After some research I tryed to compile usbcore.ko, but I do not know how to get this module. I tryed to select "Drivers -> USB -> USB Host" as module (M) in the kernel menuconfig. But this does not help.
Can anyone help me?
Is the missing usbcore.ko causing the error when loading usbserial.ko or is it a different problem? (The device has already USB OTG/Host features - I can connect a mouse or an USB stick)
What do I have to change in the kernel config so that I get usbcore.ko?
Thanks.

I get same error when I try to load cfg80211.ko module that I cross-compiled using compat-wireless-3.6.8-1
Code:
cfg80211: Unknown symbol kmem_cache_alloc_trace (err 0)
What do I have to do? Do I need to recompile kernel or is there a variable to set before make command to not use kmem_cache_alloc_trace function?
