I have tested both my phone and a USB drive.
The USB is recognized in lsusb, but it can't find the partition on the USB, and I have confirmed on other PCs that the USB works.
The phone gives no results.

Kernel compiled by Genkernel.

USB drive may not have partition. Some have a filesystem without partition table

What, if any, device nodes are added to /dev when the USB device is connected? What is the output of file -s on each of those nodes? What is printed in dmesg when the device is first plugged in?

When connected, it only shows as /dev/sdc.

file -s output:
Code:
/dev/sdc: Linux rev 1.0 ext4 filesystem data, UUID=36161b1b-ffffa0ad-4f8b-ffffbe3c-7b33336c56fe, volume name "NeatUSB" (extents) (large files) (huge files)

CanadianOtaku,

What happens when you try
Code:
mount /dev/sdc //mnt/someplace
