usb memory stick

[nozz]

Hi,
I am using redhat 9 and have a USB memory stick.
The stick works in 2 machines but doesn't work in one particular machine. When running
mount -t vfat /dev/sda1 /mnt/mem
I get
mount: /dev/sda1 is not a valid block device

the same occurs for sda0, sda4 etc.

There is nothing in /proc/bus/usb. There should be the following mdules in there I think (within /proc/bus/usb/drivers):

usb-storage
hid
hiddev
hub
usbdevfs

I have tried to load these modules using modprobe. They all load except for hiddev and hub. It claims it can't find the modules. Even so, these loaded modules don't show up in /proc/bus/usb/drivers.

lsmod produces:

I think the key is to having these drivers showing in /proc/bus/usb/drivers but I seem to have hit a brick wall.

Any help greatly appreciated,

cheers

Run dmesg to see if the device is detected. And if so, which device it uses.

Hi, thanks for the reply.

nothing in dmesg relating to the stick.

If the machine complains about hiddev and hub modules are missing, maybe they aren't installed? If I remeber correctly, hiddev has to do with Human Interface Device, i.e. drivers for USB devices such as keyboard, mouse, and possibly emory stick.

Do a 'tail -f /var/log/messages' to see what happens when you insert/remove the device. Does anything get logged at all?
