Device is not listed in /proc/bus/usb/devices

Mark Hobley · External Since: Aug 31, 2004 Posts: 198

I have been given a USB dongle made by an unknown vendor, and I plugged it
into my laptop, expecting to somehow be able to identify it. I was expecting
an entry to appear in /proc/bus/usb/devices as the dongle is plugged in, but
the file does not change. All I have listed is the host controller:

T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0
D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=0000 ProdID=0000 Rev= 2.06
S: Manufacturer=Linux 2.6.18-4-686 uhci_hcd
S: Product=UHCI Host Controller
S: SerialNumber=0000:00:07.2
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 2 Ivl=255ms

Do I need to run something to update or refresh the list, or is the device
broken?

Thanks in advance to anyone who can help.

Mark.

Not all devices register. i.e. A DIY IrDA usb dongle. Some cameras don't
do much USB wise until you try gphoto2 --auto-detect --get-all-files.
Although card readers are probably a better choice these days since they
don't use battery life from the camera. Assuming the device isn't broken
to start with. In theory something should have shown up in dmesg.

Of course it would help to have more information, like Distro + Distro
Version, or Kernel + Kernel Version, or something about what the device
in question is supposed to be? For all we know, you're trying to plug a
Trojan Condom into your usb port, which under usual conditions is
expected to give the described behavior. If we had more information, we
could probably identify that it was a known problem with Distro, Kernel,
Product, and this is how you fix it (upgrade).

Not having additional information or very good psychic abilities, I'd
have to guess that your ham sandwich is too cold to register in the usb
port. Just a guess though.

I am using Debian Etch (Kernel 2.6.18-4-486).

The device is a USB bluetooth dongle, but it has no numbers or manufacturers
name on, so I don't know anything about it.

I wanted to see if I could somehow transfer files between my mobile phone (A
Samsung D500) and my computer via bluetooth. I am hoping I can somehow mount
the phones media directory so that it is visible via my computer.

dmesg reveals the following, but I think this relates to the "bluetooth"
package, rather than the dongle, because these message still appear with the
dongle removed:

Bluetooth: Core ver 2.10
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: L2CAP ver 2.8
Bluetooth: L2CAP socket layer initialized
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: RFCOMM ver 1.8
hub 1-0:1.0: over-current change on port 2
hub 1-0:1.0: over-current change on port 1

Regards,

Mark.

It is not installed by default and may not be supplied in the initial
install package. try apt-get, otherwise Sourceforge.
