USB flash drive + Linux 2.4    [ Software ]

Got a 256MB Lexar JumpDrive for my birthday, and needed to use it with my Debian box at work.   I've never twiddled around with this hardware under Linux before, but after a bit of googling, I found that you need to do a:

# modprobe usb-uhci

or

# modprobe usb-ohci

depending on your hardware, followed by a:

# modprobe usb-storage

Your device should then be recognizable by the kernel.   A 'dmesg' should show something like:

usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.275 $ time 11:48:27 Aug 2 2003

And then you should be able to mount the flash drive, which shows up as a SCSI device:

# mount /dev/sda1 /media

'vfat' filesystem support is necessary to mount the drive, but that should be present in most linux kernels. If not, time to do the kernel-recompile dance or grab a module and get it up and running.
