[gentoo-user] Mounting USB Storage Devices

[Matthias Schweinoch]

Hi all,

I'm running Gentoo 2005.0 with an up-to-date portage tree, and I'm
having some trouble getting an external USB harddisk running. My kernel
is a 2.6.11-gentoo-r9. I have compiled USB support and SCSI
support into the kernel.

When I attach the harddisk via USB, the following output is produced in
/var/log/messages:

Jul 12 23:47:25 genbox usb 1-1.1: new full speed USB device using
ohci_hcd and address 6  
Jul 12 23:47:25 genbox scsi2 : SCSI emulation for USB Mass Storage
devices  
Jul 12 23:47:25 genbox usb-storage: device found at 6 
Jul 12 23:47:25 genbox usb-storage: waiting for device to settle before
scanning  
Jul 12 23:47:30 genbox Vendor: TOSHIBA   Model: MK4004GAHRev: 0811 
Jul 12 23:47:30 genbox Type:   Direct-Access  ANSI SCSI revision: 00 

Jul 12 23:47:30 genbox Attached scsi generic sg0
at scsi2, channel 0, id 0, lun 0,  type 0  
Jul 12 23:47:30 genbox usb-storage: device scan complete 
Jul 12 23:47:30 genbox scsi.agent[8603]: disk at
/devices/pci:00/:00:03.0/usb1/1-1/1-1.1/1-1.1:1.0/host2/target2
:0:0/2:0:0:0 

Running 'lsusb' gives me the following for device 6:

Bus 001 Device 006: ID 2735:1005

'sg_scan' produces the following ouput:

/dev/sg0: scsi2 channel=0 id=0 lun=0 [em]

I would think this all looks pretty good, i.e. I would expect to be able
to mount the drive by doing something like:

mount /dev/sg0 /mnt/usbstorage

However, if I try this, mount produces an output saying that the device
is not a block device. 

I'm pretty much out out ideas, and I'd welcome any suggestions.

Sincerely,

  Matthias

Hi Boyd,

  negative: NO SUPPORT FOR OGG!!!


 Well, doesn't help me (see above) but hopefully someone else reading the 
 thread can use your review / recommendation. 


I just bought myself an HD 300 from MPIO. You can check out the device at
www.mpio.com. It's recognized as an external usb harddisk under linux, so
/var/log/messages tells me. I haven't gotten around to actually mounting it
yet - I actually got this only 2 days or so ago, and my Kernel obviously
still has some SCSI issues, so right now I can't mount any USB drives... I
will try to get it running over the weekend.

As for the device itself, I think it's rather neat. It supports OGG, MP3,
ASF, WMA and WAV (though it doesn't play just ANY wav format: I couldn't
convince it to play a mono wav file...). Also, it can record via line-in or
an integrated microphone, and even from radio (which is also included, and
has a rather decent reception, AFAIK).

It does have 3 issues which I find annoying: 

1. The user interface, i.e. the touch pad/keypad is good enough for setting
the volume, but it's a rather awkward way to navigate the directories. Also,
the keypad has 2 trigger points (i.e. if you press it 'lightly' you get the
first trigger... if you press a little harder, you get a second trigger...
but there's no difference between the two actions), which makes for some
confusion. 

2. The drive/response time is somewhat slow. When you want to navigate the
directory, you may click on a file, and it will take 3-6 seconds to actually
change the directory or start playing the file. However, if you run through
a playlist or play all files in a directory, this is not an issue.

3. It needs a separate charging unit and doesn't get charged via USB. Not a
real problem, but an annoyance.

So, summing up: Loads of features (radio, recording, integrated equalizer
with many presets and configurable, media formats) which outperform the
iPod, AFAIK, but a slightly awkward user interface (where the iPod shines). 

Ah yes, one other thing: Sound is superb!


Matthias
