LFS 6.3 don't detect Apple usb to ethernet adapter

Hi guys,

I've installed a LFS 6.3 system in my MacBook Air as a practice for a subject at Universty and all works smoothly but when they asked to try and test a DHCP connection via wired connection (usb to ethernet adapter) I realized that this wasn't recognized by LFS system and it's a requisite to have a wired connection to pass the interview.

I've tried all I know. I've installed the ifconfig command and lsusb to have a detailed view of whats happening but when I pluged in the adapter the lfs prompts it's information.

Runing lsusb prompts the bus information for the adapter:

Bus 002 Device 003: ID 05ac:1402 Apple Computer, Inc.

Runing ifconfig only prompts the loopback interface configuration.

Any ideas?

Thank you very much in advance.

I don't know anything about the device. Sorry. But I would start by confirming that the necessary USB and networking modules are set in the kernel configuration. Also, there may be a kernel driver module for the device. Searching with the device's USB vendor ID leads to here for a possible kernel driver module depending on the installed kernel version...
Or, you may need to find and install a driver.

I fully agree with stoat's post, but I want to add one more thing:

LFS 6.3 comes with a rather old kernel (2.6.22), which might not yet have the options required for your adapter/device.

If, after following stoat's advise, you still are unable to get this working you might want to have a look at a newer kernel. Support for Apple related devices has greatly improved over the years.

Smile Kernel 3.5 comes with usb to ethernet compatibility!

So as you say thats the driver but kernel 2.6.x does not come with compatibility module for usb to ethernet adapter. Eventually I started again with LFS 7.2 that comes with kernel 3.5 and after prompting the menuconfig I selected the usb to ethernet module and all works smoothly.

Thank you again for all your help.
