USB Device Not Recognized

ashields124 · 07-11-2011, 10:09 AM

At my office, we use RedHat 4.8. Recently we installed it on a new computer. The computer is not recognizing IronKey flash drives. It does not show up when I type fdisk -l as a listed device.

dmesg produces this output:
scsi15: SCSI emulation for USB Mass Storage devices
then it lists the specifics of the flash drive.
sr0: scsi3-mnc drive: 52x/52x cd/rw xa/form2 cdda tray
Attached scsi CD-ROM sr0 at scsi15, channel 0, id 0, lun 0
USB Mass Storage device sound at 23

tail -f /var/log/messages also reads that it is there.

When I use other flash drive, it will write to to sdb1, and I can see that in dmesg, but this one is not appearing.

I am thinking something may have went wrong during the install and it is a kernel problem, and I will have to reinstall. Is there any other options before trying that?

Hi!
Normally USB devices automatically are recognized:
Terminal: "lsusb":

Code:

[alfredo@localhost ~]$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 058f:6387 Alcor Micro Corp. Transcend JetFlash Flash Drive
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
...

In my case it' s a Transcend; the hexcode 058f:6387 shows the vendor and the device.
Is it recognized on another computer? Maybe it is damaged.

It recognizes it's there when I run lsusb, but I can't mount it because there is no sdb assigned. It does work on other computers.

Ironkey devices are NOT 'regular' USB flashdrives. Did you check Ironkey's support site?
https://support.ironkey.com/article/347

And since you're using Ironkey and RedHat Enterprise...you can call either of them for support, since you're paying for it.

Hi!
Maybe you should search with the hexcode to find out the vendor and name of the device and/or search for "problem name" or "problem hexcode" or "linux ...".

The OP already said that it's an Ironkey USB drive.

I've already tried doing the steps in that link. I was hoping maybe there was a simple solution that I didn't think of before calling them. Thanks though.
