Severity: normal

usbmount doesn't find the vendor and model for my
Kingston DataTraveler usb keychain. For some reason,
the files it looks for:
/sys/block/uba/uba1/[../]device/{vendor,model}
don't exist on my machine. There is no symlink
/sys/block/uba/uba1/device
There is a symlink from /sys/block/uba/device to
../../devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1:1.0/
But that directory only contains
bAlternateSetting bInterfaceProtocol block@ driver@
bInterfaceClass bInterfaceSubClass detach_state power/
bInterfaceNumber bNumEndpoints diag
However, one directory up, i.e.
../../devices/pci0000:00/0000:00:1d.0/usb1/1-1
contains
1-1:1.0/ bMaxPower configuration idVendor serial
bConfigurationValue bNumConfigurations detach_state manufacturer speed
bDeviceClass bNumInterfaces devnum maxchild version
bDeviceProtocol bcdDevice driver@ power/
bDeviceSubClass bmAttributes idProduct product
and the files manufacturer and product contain
Kingston
and
DataTraveler 2.0
The patch below makes usbmount find these files. But it's a bit of a
hack. Maybe this is a bug in udev, or a bug in my device? If you do
add something like this patch, maybe it should instead be more
systematic, e.g. something like (untested):
for pth1 in "" "../"; do
for pth2 in "" "../"; do
for fn in vendor manufacturer; do
if test -r "/sys$DEVPATH/${pth1}device/${pth2}$fn"
vendor=...
break
and similarly for model/product.
I should also point out that udevinfo finds this info:
# udevinfo -a -p /sys/block/uba/uba1 | grep Kings\\\|DataT
SYSFS{manufacturer}="Kingston"
SYSFS{product}="DataTraveler 2.0"
I wonder if usbmount should just use udevinfo instead of
searching through /sys?
Thanks for any help,
Dan
