 Posted: Fri Jun 22, 2012 8:37 pm Post subject: [Solved] USB access |
 |
|
Well, I thought I was going to have to ask how to mount a usb device because neither my IOMEGA_HDD nor any flash drive would show up in Dolphin. Now they show up but I get this:
| Quote: | | An error occurred while accessing 'IOMEGA_HDD', the system responded: An unspecified error has occurred: Not Authorized. |
I tried "gpasswd -a mark usb", but that did not give me access.
Thoughts?
~Mark
Edit: I tried a mount command, but it says it can't be found in /etc/fstab or /etc/mtab. Is this going to require a kernel recompile?

First, is this a polkit 106 question ?
If not, (Dolphin is xfce, right ?), does 'udisks --mount' works on the drive ? |

mark2,
As root, try to mount a partition on the device manually.
dmesg will show the partitions available after you connect the device, then
| Code: | | mount -t vfat /dev/<partition> /mnt/someplace |
-t vfat works for FAT[12,16,32] use -t ntfs, or -t ntfs-3g if the filesystem is Windows ntfs and so on.
I'm not expecting it to work - the error messages will be informative.

@VoidMage: sorry, I am so new to this that I don't even know what polkit106 is. I'm running a KDE desktop, and udisks --mount did nothing.
NeddySeagoon: dmesg spewed out more text than I can copy, but the two devices (IOMEGA_HDD and Kingston) show up here:

I don't know how much help this will be. I am a real rookie here and didn't even get a gui until yesterday. But I don't mind doing the work. I just don't understand what to put in that mount command.
Thanks,
~Mark

mark2,
You are looking for a block like this at the point in dmesg when you connect your USB drive
| Code: | [22106.676110] usb 2-6: new high-speed USB device number 3 using ehci_hcd
[22106.814908] usb-storage 2-6:1.0: Quirks match for vid 13fe pid 3600: 4000
[22106.814969] scsi9 : usb-storage 2-6:1.0
[22107.857687] scsi 9:0:0:0: Direct-Access USB DISK 2.0 PMAP PQ: 0 ANSI: 0 CCS
[22107.858110] sd 9:0:0:0: Attached scsi generic sg10 type 0
[22109.154499] sd 9:0:0:0: [sdi] 7827456 512-byte logical blocks: (4.00 GB/3.73 GiB)
[22109.155114] sd 9:0:0:0: [sdi] Write Protect is off
[22109.155125] sd 9:0:0:0: [sdi] Mode Sense: 23 00 00 00
[22109.155740] sd 9:0:0:0: [sdi] No Caching mode page present
[22109.155749] sd 9:0:0:0: [sdi] Assuming drive cache: write through
[22109.160226] sd 9:0:0:0: [sdi] No Caching mode page present
[22109.160236] sd 9:0:0:0: [sdi] Assuming drive cache: write through
[22109.188039] sdi: sdi1
[22109.191462] sd 9:0:0:0: [sdi] No Caching mode page present
[22109.191471] sd 9:0:0:0: [sdi] Assuming drive cache: write through
[22109.191479] sd 9:0:0:0: [sdi] Attached SCSI removable disk |
The important line is | Code: | | [22109.188039] sdi: sdi1 |
which tells of /dev/sdi1 as the only partition on the drive, so thats what I should try to mount.
Its easier to see these blocks of data if you look at dmesg, note whats at the end, then connect the USB device and look at dmesg again.
The numbers at the start of each line are seconds since boot. Thats a kernel option.

Excellent, NeddySeagoon!
The IOMEGA_HDD was sdb1 and the KINGSTON was sdc1. Using the command you specified, I am now able to browse the files on each usb drive. Now my question becomes: How would I set things up so that I could access any usb drive that I connect automatically without having to manually mount these drives?

mark2,
I don't use automounting at all, so I'm no help.
Your testing has confirmed that the low level stuff all works.
You probably want to start a new thread asking about automounting in your GUI of choice and explain that it all works manually.
