I have the minor number of usb devices in /dev/bus/usb trunkated. where do I look for debugging this problem? kernel? filesystem code? udev? glibc? something else?
foo:/dev/bus/usb/003# ls -l total 0 crw-rw-r-- 1 root root 189, 0 Sep 26 11:52 001 crw-rw-r-- 1 root root 189, 1 Sep 26 11:52 002 foo:/dev/bus/usb/003# cat /sys/class/usb_device/usbdev3.2/dev 189:257 foo:/dev/bus/usb/003#
no wonder my app fails talking to the device, it was created with the wrong minor device number.
debian package with backport to sarge: Version: 0.100-1~bpo.1
udev config: # usbfs-like devices SUBSYSTEM=="usb_device", PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", \ NAME="%c"
for now I can work around it with "rm -rf /dev/bus", but can someone help me finding the real solution?
