.config file for using B1-750 souce code

Hello,

 

I would like to use an app that requires a USB cable with an FTDI FT232R serial chip in it.  When I plug the cable into an On The Go adapter, and then plug that into the Acer Iconia One 7 (B1-750), the Acer finds the FTDI cable, and recognizes its model and serial number, but it does not "attach" it. 

 

It's clear that Acer did not configure the kernel to install the FTDI drivers for the Iconia One 7, so I want to do that now, either by recompiling the stock kernel with FTDI support, or by just creating a module that I can insert into the stock kernel when needed.

 

FTDI posts a "how to" document here, that makes the process pretty straight forward if I had the source code and the ".config" file for the B1-750:

Acer has already posted the source code for the B1-750 here, and it already has FTDI drivers that could be used, located in the /linux-vespa2/kernel/drivers/usb/serial directory:

But my problem is, there is no ".config" file that I can find, either by looking in that Acer source code or looking on the B1-750 itself.

 

Would Acer please post the .config file for the B1-750, so we can actually do something useful with that source code?

 

It's not possible to start the "Menuconfig" application in Linux, without first having a .config file for the B1-750.

 

I have experimented with using the generic kernel config file in the source code posted by Acer, found in the source code at "/linux-vespa2/kernel/arch/x86/configs/x86_64_defconfig".  But running the "make" command using that as a .config file will generate lots of errors relating to files and folders that don't exist in the source code.

 

To use the Acer source code, I need the specific .config file used by the B1-750 device, not just a generic x86_64 file.

 

I tried pulling the /proc/config.gz file from the B1-750 itself, but that file apparently does not exist, and running the extract-ikconfig script gives me a "Cannot find kernel config" error. So, no way to get the .config file from the device itself.

 

So my only hope here is if Acer posts the .config file.

 

Please!
