Unable to get OTS (off the shelf) sticks to mount (Auto or
otherwise). Seems I get inconsistant results even with the same
device!
I have searched thru the post using 'USB mount' & 'USB' and have
gotten hints but without success.
Basically, the device partiton info is not being recognized as it
should. The device is handled fine in windows XP.
The board is a TS-7300 with a Debian distro. More info follows:
Did modprobe for vfat, usb-storage, & usbserial
Then dmesg shows
