I have a Samsung phone GT-B3210. For some time I was unable to find working Windows drivers for it. I eventually gave up looking. Then one time I was charging phone over its USB port and booted Ubuntu and was pleasantly surprised when I saw phone's μSD card reader on my desktop.
I now need to switch to Gentoo and would like to be able to work with phone there too. Lsusb tells me it's detected as
Bus 007 Device 006: ID 04e8:663f Samsung Electronics Co., Ltd SGH-E720/SGH-E840
but lsmod wasn't very helpful. On the list of loaded modules, I wasn't able to find one which looks like it's related to the phone.
Is there some other way to see which module is used by the telephone?
