Re: Jump Drive



Output from dmesg I see after putting the device in a USB port immediately after a re-boot is:

usb 1-6: new high speed USB device using address 2
usb 1-6: device not accepting address 2, error -71
usb 1-6: new high speed USB device using address 3
usb 1-6: device not accepting address 3, error -71

If I take it out, and put it back in again, I get the same messages for address 4 and 5, etc.

I was using the "front" panel USB ports on my PC. I vaguely remember someone I know having problems with their front panl USB port, so I tried plugging it into one of the USB ports on the "back" of the PC, and wonder of wonders, I can see the device and mount it on my FC2 system.

Went to a friends newer Dell desktop running RHEL3 Workstation, it worked on his system with both the front and back USB port.

Thanks for the trouble you took to reply, appreciate it.

I am running FC2, don't see anything when I plug the drive in.

You need to know which device it's showing up as.  Take a look at the
output of "dmesg" and look for the entries involving that device.  It
will probably look something like this:

usb 1-6: new high speed USB device using ehci_hcd and address 4
SCSI subsystem initialized
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 4
usb-storage: waiting for device to settle before scanning
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
  Vendor:           Model: USB FLASH DRIVE   Rev: 1.01
  Type:   Direct-Access                      ANSI SCSI revision: 00
usb-storage: device scan complete

SCSI device sda: 2031616 512-byte hdwr sectors (1040 MB)

 sda: sda1
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0

If that's the case, it's device "sda" (see last line above).  In my
case, partition 1 is used, so:

        mount /dev/sda1 /mnt/cdrom

would make it show up as /mnt/cdrom (I just used /mnt/cdrom as an
example...you could mount it as /mnt/floppy or create your own spot
and mount it there).

How do I get Fedora to recognize and read a Lexar JumpDrive?


Err.... Have you tried plugging it in? FC3 and 4 at least should automatically find it and mount it for the current logged in user, older versions should report the new device to the console and then allow it to be mounted manually.
