I'm using Arch Linux on my laptop, and have ASUS Transformer TF101 tablet with Android 4.0.3. And yes, it doesn't recognize my Transformer as USB device. In Android 2.3.6 (which I have on my phone) it just prompts me to allow connection as USB storage, nothing more.
To mount Transformer and be able to use for data transfer through MTP, I did the following (as root):
1. Installed libmtp (Library implementation of the Media Transfer Protocol):
# pacman -S libmtp
2. Installed mtpfs (A FUSE filesystem that supports reading and writing from any MTP device):
# pacman -S mtpfs
3. Created a mount point:
# mkdir /media/Transformer
4. Changed permissions on that directory:
# chmod 777 /media/Transformer
5. Mounted my tablet:
mtpfs /media/Transformer -o allow_other
6. ...
7. PROFIT
Now, I can access the filesystem on my tablet using terminal. The outstanding issue I still have - when I try to navigate over it from Dolphin (as my local user not root), it blocks the access for some reason:( Need to find out the solution...
