Kernel Update on live USB stick Ubuntu 9.10

[swiatmar]

Hello!!

I would like to update my Kernel from 2.6.31.14 (from liveCD) to the 2.6.31.17, because of my modem problem (huawei e 169).>UBUNTU 9.10<
I know that I can do it trough synaptic- but the problem is when I restart my pendrive, the kernel want be recognized. I think I have change something in some boot documents- but it looks here everything a little bit different than with HDD install:there is no menu.lst , etc.
Can somebody give me an advice how to do it?
Thanks

Is there something like menu.lst in live usb installation.
When I upgrade my kernel to 2.6.31.17 I am unable to start my ubuntu from usb ......
Does anybody know how the boot process looks like by live usb installation?
