USB
21 February 2005
Status
- Olympus
Stylus 400 Digital Camera, Archos Recorder 20GB, and Flash Drive are
all recognized automatically on Sigillo, Trevi, and likely others, and
can be mounted with "mount /flash" -- make sure /etc/fstab has
/dev/sda1 using vfat
- Back-up Q Penr-35u2f
mounts fine on Spello's USB2.0 with "mount /mnt/tv1" -- make sure
/etc/fstab has /dev/sda1 using ext2 -- unmounting and remounting is
unproblematic
Guides
Installation history
GPS
GPS Model Navius NSA-U3 is supported by gpsd, but I'm not seeing it actually recognized as a device.
Flash drive formating
I tried to format a 512MB flash drive with ext2 and failed --
the command to write the file system would time out and generate errors
in dmesg. It may be the fat16 file system is hardcoded -- at any rate I
decided to revert to it.
I then used parted as follows (I actually first created a partition on cfdisk, but I don't think it mattered):
parted /dev/sdc
print
rm 1
(removes the first and only
partition)
mkpart primary fat16 0 507MB (make a new partition -- fat16 because less than 2GB)
mkfs
1
fat16
(make a fat16 file system on the first and only partition)
toggle 1
boot
(make the stick bootable)
(parted) print
Disk /dev/sdc: 513MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 0.51kB 507MB
507MB primary
fat16 boot, lba
Nice and clean, and all instantaneous. However, when I gave the size as
513MB, which is what parted says it is, I got "Partition 1 has
different physical/logical endings". I then used fdisk -l /dev/sdc to
get a value of 507MB, and this resulted in a clean formating, and the
drive mounted. However, the hardware appears to be shot and kept
producing errors during copying.
Flash drive on non-powered hub
Starting with kernel 2.6.16, the kernel checks if enough power
is available to mount a USB drive on a non-powered hub, and doesn't
create the device node if there isn't (you'll get "no configuration
chosen"). Very annoying, as my flash drive does fine on the non-powered
hub in the keyboard, and the machine itself is in another room. It's a
good thing I didn't depend on this happening in the 30 seconds I often
have for this before class!
Anyway the workaround is simple:
echo -n 1 >/sys/bus/usb/devices/1-3.3/bConfigurationValue
Check dmesg to find the right value for 1-3.3. The value "1"
is correct for the current flash drive but could change for another
drive. The device node is now created as before -- except you get "usb
1-3.3: new config #1 exceeds power limit by 78mA".
I put this in a script called flash. It will shift to 1-2.3 if the quickcam driver is unloaded.

Works fine on Spello's USB2.0 card on boot:

Bus 001 Device 001: ID 0000:0000
So the drive shows up as ID 067b:3507 Prolific Technology, Inc. Mounts
on /mnt/tv1 with ext2. On trevi, do this, to avoid confusion with
cybers:/mnt/tv1:
mount spello:/mnt/tv1 /mnt/tv1
This works. Television footage flows without problems. Copying
speed seems to be comparable to firewire -- precise benchmarks not yet
done. Note also that spello's NIC is operating at Gbit/s and cybers for
some reason fell back to 100 Mbit/s, so spello should be faster. A real
comparison would be spello firewire to spello usb2; cf. todo.
Now unmounting and remounting: works flawlessly! To unattach and then reattach without rebooting, follow this procedure:
- trevi: umount /dev/tv1 (unmount the nfs-mounts)
- cybers: stop nfs-kernel-server (this frees the exported drives)
- cybers: umount /dev/tv1
- cybers: start nfs-kernel-server (make /vh available again)
- detach the USB cable (may not be needed)
- turn off the drive enclosure unit
- give the drive a rest to cool down
- turn on the drive enclosure unit
- wait until the drive is up to speed (a few seconds)
- reattach the USB cable if it was detached
- wait a few seconds for the drive to reattach
- mount /mnt/tv1
This seems robust and straightforward. You can't daisy-chain USB devices, but
they're easy to turn on and off, and you can presumably use extended hubs.
Olympus Stylus 400 Digital Camera
13 June 2004
I searched Linux USB devices and found the status is OK; the ID is 0x07b4:0x0102; see details.
You can mount it on /mnt/flash, like the USB flash card -- this is also
a scsi emulation (note that the battery has to be in for the camera to
be detected):

Flash drive
17 May 2004
Software and guides
Inserted the USB drive in the powered USB hub and it started pulsing slowly. lsusb showed it as
Bus 003 Device 006: ID 08ec:0012 M-Systems Flash Disk Pioneers
This auto-loaded three kernel modules:
sd_mod
usb_storage
scsi_mod
In /var/log/messages I see it's assigned to /dev/sd1:

I created /mnt/flash and mounted with this command:
mount /dev/sda1 /mnt/flash -t vfat
Worked instantly. df shows capacity:
/dev/sda1
119684
0 119684 0% /mnt/flash
I copied over a file and unmounted -- this just works!
External drive
After installing the old /vs -- a 320GB drive -- on Gubbio, I
kept having I/O problems that made the drive non-functional. I removed
it and placed it in an external encloser, hooked it into Clitunno's USB
port, and issued (more or less a guess):
mount -t ext2 /dev/sdc1 /mnt/vsa
It just mounted. I deduced the others would mount on /dev/sdc2, 3, and
4, and ran e2fsck /dev/sdc4 to prove it; looks fine. Now of course one
consequence of moving to USB is that the copying will be slower, and
presumably easier on the drive, so maybe this is a good thing. So far
no errors. In /var/log/messages I see this:
clitunno kernel: hub.c: new USB device 03:00.1-2, assigned address 2
clitunno kernel: usb.c: USB device 2 (vend/prod 0x67b/0x3507) is not claimed by any active driver.

clitunno insmod: Using /lib/modules/2.4.21-193-smp/kernel/drivers/usb/storage/usb-storage.o
So the kernel module loads and the driver works. However, the I/O
problems persist, so the drive is likely shot. I umount and unhook it;
to reattach, remove the usb-storage module and then modprobe it. Run
lsusb to see it activated -- "Prolific Technology, Inc." I did the same
thing on Sigillo and got the same result with the 2.6.3 kernel -- SCSI
emulation. Mounted instantly with
mount -t ext2 /dev/sda1 /mnt/vsa
Scanner on vacation
In late October 2003, the scanner stopped working -- not sure what
triggered it. Same problem in 2.4.20 and 2.5.69, so unlikely to be
kernel-related. Don't recall what brought it back -- perhaps the new KDE scanner software?
USB and VMware
On 19 November 2002, I was unable to install a USB printer driver and
a USB driver for the PDA cradle on the guest Win98 OS because "The
specified device appears to be claimed by another driver (serial) on the
host operating system which means that the device may be in use. VMware
Workstation cannot safely take control of the device until the host driver
is unloaded." So I need to find a way to stop the USB bus temporarily
on Linux -- I've written VMware support for a more elegant and stable
solution.
Wrong USB driver
At some point, in upgrading from 2.4.16 to 2.4.19 on gubbio or cyberspace,
I realized that I had been running the wrong USB driver -- I had been
running the (I think) UHCI alternate instead of the regular, which I should
have been running. See also the FAQ
on UHCI and OHCI. Spello has "00:07.2 USB Controller: Intel Corp.
82371AB PIIX4 USB (rev 01)" and thus needs the inferior UHCI. Check
the details with "cat /proc/bus/usb/devices" -- at least on
Spello, usbfs is installed and running.
Lost mouse and keyboard on cyberspace
A shocking experience with a happy ending on cyberspace, 27 Sep 2002.
I tried to install a new USB mouse and ran SaX2. It froze and I had to
reboot (never run this beast within X-windows; it works fine if KDE is
not loaded). I then lost my normal mouse and didn't know how to get it
back. Finally I figured out that the mouse is defined in /etc/X11/XF86Config.
I found some help online, but then realized that gubbio's /etc/X11/XF86Config
would have all the info I needed, as indeed it did:
Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "ButtonNumber" "5"
Option "Device" "/dev/mouse"
Option "Name" "Autodetection"
Option "Protocol" "imps/2"
Option "Vendor" "Sysp"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "on"
EndSection
So this was a lesson in configuring X -- supremely simple in the configuration
file, and a nightmare with SaX2.

Now, could it be that the lid-core is messing up the usb drivers? This
is a new element in a system that I believe was actually working great
before. So you've introduced two new problems, usb and cdrw, while solving
the gigabus and firewire problems. It's funny how those latter two, which
sound hard, are working great and caused me little trouble, while what
was already working has been messed up. On the other hand, if this is
the problem, then SuSE's kernel should work fine, which it's not doing.
