 |
|
Thanks to Lysdexia at everythingusb.com forums for this one:
| Quote: |
The JumpDrive works swimmingly with the newer linux kernels. Simply mount them as a scsi device:
mount /dev/sda1 /mnt/JumpDrive
(you will have to create the "JumpDrive" directory yourself)
I use my 64m JumpDrive on RedHat 8.0 daily...
|
It worked for me using the Gentoo 2.6.8-r3 kernel.
Hope this helps.  |

| First off how did you get it to assign the jumpdrive to /dev/sda. On my system it is assigning /dev/uba to the lexar jumpdrive, but I can't access it. fdisk can't read a partiion table, and there is no /dev/uba1. |

| Well I don't know about the problem the last guy is having, but this worked A+ perfectly for me! For once, I found something that's superbly easy to do. (Gentoo w/X.org+Fluxbox). |

HOWTO
1. Plug it in.
2. Check dmesg
Here's mine:-
| Quote: | usb 1-2: new high speed USB device using ehci_hcd and address 2
scsi2 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
Vendor: Easy Model: Disk Rev: 2.00
Type: Direct-Access ANSI SCSI revision: 02
SCSI device sdb: 256000 512-byte hdwr sectors (131 MB)
sdb: Write Protect is off
sdb: Mode Sense: 03 00 00 00
sdb: assuming drive cache: write through
SCSI device sdb: 256000 512-byte hdwr sectors (131 MB)
sdb: Write Protect is off
sdb: Mode Sense: 03 00 00 00
sdb: assuming drive cache: write through
sdb: unknown partition table
Attached scsi removable disk sdb at scsi2, channel 0, id 0, lun 0
usb-storage: device scan complete
|
Note device = sdb on mine
3. mkdir /flash
4. mount /dev/sdb /flash |

Try 'ls -l /dev/uba'? It might be a bad symlink.

I'd also like to re-emphasize that the flash drive being /dev/sda is only incidental -- SCSI and SCSI-emulation drives(including SCSI, the usb_storage driver, and most anything SATA) get assigned sda, sdb, etc. in the order they're added. If you want a guaranteed device name, and you're using udev, you can write a udev rule to name it whatever you want. USB flash drives are particularly nice for this since they come with a unique serial number that udev can use to discriminate even a particular jumpdrive from the rest of your devices.
Also, from magic919's post: | Code: | | usb-storage: waiting for device to settle before scanning |
This particular step takes a few seconds, so don't panic if it "sticks" there a moment.

Well I'd just like to reiterate that I didn't have any problems. The 128MB Lexar Media JumpDrive showed up on /dev/sda1, even with the files that I had loaded up on it from wayyy back when, back when I was using WinXP. I took em off with no problem and even loaded up the JumpDrive with updated files (going to my brother's with proggies to help his PC, running WinXP =P, out some, help optimize it as much as it CAN be optimized under WinXP, rofl...)
And just in case my bro's PC has a particularly malicious virus on it, I chmod'ded the files on my JumpDrive to +rx-w, so it shouldn't be able to mess with the files and corrupt them before I even get a chance to install the Spybot and McAfee Virus and Firewall, and especially TweakNow Powerpack 2006. For anyone who's using WinXP, those programs are a must for a safe and fast (for) WinXP. Just something you them dual booters to look out for. |
