Problems Mounting USB Drives

[Majwell]

I am having problems mounting any type of USB drive, be that external hard drive or thumb stick, with my USB2 PCI card. USB1 seems to be working relatively well.

There are no sd* devices in /dev after plugging in the devices. However, running dmesg, we see thiis for the external harddrive:

[18127019.472000] usb 5-2: new high speed USB device using ehci_hcd and address 2

and this for the thumbstick:

[18127552.452000] usb 5-2: new high speed USB device using ehci_hcd and address 4
[18127553.048000] SCSI subsystem initialized
[18127553.128000] Initializing USB Mass Storage driver...
[18127553.128000] scsi0 : SCSI emulation for USB Mass Storage devices
[18127553.128000] usb-storage: device found at 4
[18127553.128000] usb-storage: waiting for device to settle before scanning
[18127553.128000] usbcore: registered new driver usb-storage
[18127553.128000] USB Mass Storage support registered.

After having the thumbstick plugged in we are seeing some "resets" of the USB device in dmesg, but still no sd* devices in /dev

[18127600.720000] usb 5-2: reset high speed USB device using ehci_hcd and address 4
[18127600.852000] 0:0:0:0: scsi: Device offlined - not ready after error recovery
[18127600.852000] usb-storage: device scan complete

Both of these devices work on other machines (OSX and WinXP Pro) and on this USB2 card in this machine when it had WinXP on it a couple of weeks ago.

Any ideas of what I can do to get USB2 working? USB1 is unacceptably slow for use with external harddrives.

After you plug in the device, do you see an entry fo it in /dev/disk/by-id?

This is what is in mine. I can't mount mine either. I have just upgraded to KDE 3.5.5.

Edit your /etc/fstab file as root, for example, start a konsole, and enter "sudo nano /etc/fstab". Enter your password when asked. Nano is a console editor so you navigate with the arrow keys not with the mouse (gets me every time). Enter the following lline:

/dev/disk/by-id/usb-Seagate_External_Drive_SG060800320-part1<tab>/media/seagate<tab>vfat<tab>rw,user,noauto<tab>0<tab>0

where <tab> means press the tab key. I have made the assumption that your removable is formatted with a vfat (also known as Fat32) file system. If this is not the case, you will have to enter the correct file system. Press Alt-B, so the old file will be backed up, then Ctl-O to save the new /etc/fstab file, and Ctl-X to exit nano.

Now navigate to the media directory in Konqueror. Create a new folder under media called "seagate". With the Seagate attached, reboot, so that the new fstab file is read. This is not strictly necessary, but it's easy to do. Then from a konsole, enter the command "mount /media/seagate". And there you have it.
