I've installed Gentoo on new laptop, after some traditional fight with kernel drivers system mostly works, but
- when i connect usb flash to any port driver is work and i can see device in /dev, but i can't mount it, "bad superblock", and even one of my usb drives shows as it have udf partition
- i was able to connect my old phone as usb drive, and it was working well

What can i do to make it works?
Seems that i didn't set some kernel options, but wich of them?

leonik375,

Welcome to Gentoo.

You need USB-storage support in your kernel and vfat filesystem support.
There is another USB block device driver. I forget what its called but it has 'slow' in its name. You don't want that one.

For NTFS formatted USB storage devices, you need FUSE in the kernel and the ntfs-3g package.
Kernel NTFS support is very limited.

For exFAT, you need FUSE and the fuse-exfat package.

Thank you for your answer
All my USB drives formatted to vFAT
i've support of vFAT buit-in in kernel
Seems that my problem in somthing else:

blkid from my laptop:
........
........
/dev/sdb: UUID="2014-11-21-14-58-16-00" LABEL="GRMCULF(X)REO_EN-RU_DVD" TYPE="udf" PTUUID="0004ad4a" PTTYPE="dos"

blkid from my work machine(mint+kde4):
........
........
/dev/sdb1: LABEL="win7" UUID="3CA7-B711" TYPE="vfat"

/dev/sdb is the same flash drive
Maybe i need to compile-out vFAT?

If you don't see sdb1 partition on your system maybe you forgot to add support for partition tables.


zgrep PARTITION /proc/config.gz


Most common are MSDOS and EFI - enabling more probably does not hurt

You were right - i did't set any partition support instead of efi, thank you very much.
Now i can mount drives under root from console, but not from KDE menu
