Problem mounting *some* USB sticks

Hello,

I'm able to mount about 1/2 of USB sticks just fine. /sd1 shows up and everything works beautifully.

However, with a Lexar stick and also Adata stick, I get a mount problem. only /sd shows up but no /sd1.

Below is the output of dmesg. It does see the USB, but says something about superblocks not being read properly. I tried both FAT32 and different block sizes but nothing works on this stick. Also, not sure why but it says ext3, ext4 when filesystem should be FAT.

So some issue with a partition. Stick shows up fine both in Windows and in Linux.

I'm on Nexus7 2013, 4,4
