Hi * I just migrate from 2.6.28.10 to 2.6.30 and have following issue: In 2.6.28.10 (and earlier kernels) listing of /sys/class/lirc/lirc0/device/ gives me following ouptput: ----------------------------------------------------- access user group date size name drwxr-xr-x root root Jun 13 08:14 .. drwxr-xr-x root root Jun 13 08:14 3-1:1.0 drwxr-xr-x root root Jun 13 08:14 driver drwxr-xr-x root root Jun 13 08:14 ep_00 drwxr-xr-x root root Jun 13 08:14 lirc drwxr-xr-x root root Jun 13 08:14 power drwxr-xr-x root root Jun 13 08:14 subsystem drwxr-xr-x root root Jun 13 08:14 usb_device drwxr-xr-x root root Jun 13 08:14 usb_endpoint -rw-r--r-- root root Jun 13 08:14 4096 B authorized -rw-r--r-- root root Jun 13 08:14 4096 B bConfigurationValue -r--r--r-- root root Jun 13 08:14 4096 B bDeviceClass -r--r--r-- root root Jun 13 08:14 4096 B bDeviceProtocol -r--r--r-- root root Jun 13 08:14 4096 B bDeviceSubClass -r--r--r-- root root Jun 13 08:14 4096 B bMaxPacketSize0 -r--r--r-- root root Jun 13 08:14 4096 B bMaxPower -r--r--r-- root root Jun 13 08:14 4096 B bNumConfigurations -r--r--r-- root root Jun 13 08:14 4096 B bNumInterfaces -r--r--r-- root root Jun 13 08:14 4096 B bcdDevice -r--r--r-- root root Jun 13 08:14 4096 B bmAttributes -r--r--r-- root root Jun 13 08:14 4096 B busnum -r--r--r-- root root Jun 13 08:14 4096 B configuration -r--r--r-- root root Jun 13 08:14 64 kB descriptors -r--r--r-- root root Jun 13 08:14 4096 B dev -r--r--r-- root root Jun 13 08:14 4096 B devnum -r--r--r-- root root Jun 13 08:14 4096 B idProduct -r--r--r-- root root Jun 13 08:14 4096 B idVendor -r--r--r-- root root Jun 13 08:14 4096 B manufacturer -r--r--r-- root root Jun 13 08:14 4096 B maxchild -r--r--r-- root root Jun 13 08:14 4096 B product -r--r--r-- root root Jun 13 08:14 4096 B quirks -r--r--r-- root root Jun 13 08:14 4096 B serial -r--r--r-- root root Jun 13 08:14 4096 B speed -rw-r--r-- root root Jun 13 08:14 4096 B uevent -r--r--r-- root root Jun 13 08:14 4096 B urbnum -r--r--r-- root root Jun 13 08:14 4096 B version -------------------------------------------------------- In 2.6.30 listing of /sys/class/lirc/lirc0/device/ gives me: -------------------------------------------------------- access user group date size name drwxr-xr-x root root Jun 13 08:18 .. drwxr-xr-x root root Jun 13 08:18 driver drwxr-xr-x root root Jun 13 08:18 ep_01 drwxr-xr-x root root Jun 13 08:18 ep_81 drwxr-xr-x root root Jun 13 08:18 input drwxr-xr-x root root Jun 13 08:18 lirc drwxr-xr-x root root Jun 13 08:18 power drwxr-xr-x root root Jun 13 08:18 subsystem drwxr-xr-x root root Jun 13 08:18 usb_endpoint -r--r--r-- root root Jun 13 08:18 4096 B bAlternateSetting -r--r--r-- root root Jun 13 08:18 4096 B bInterfaceClass -r--r--r-- root root Jun 13 08:18 4096 B bInterfaceNumber -r--r--r-- root root Jun 13 08:18 4096 B bInterfaceProtocol -r--r--r-- root root Jun 13 08:18 4096 B bInterfaceSubClass -r--r--r-- root root Jun 13 08:18 4096 B bNumEndpoints -r--r--r-- root root Jun 13 08:18 4096 B modalias -r--r--r-- root root Jun 13 08:18 4096 B supports_autosuspend -rw-r--r-- root root Jun 13 08:18 4096 B uevent ------------------------------------------------------------ As You see, in 2.6.30 there is no entry like busnum. As my initscripts relay on this entry - I have issue with my system initialization. Is above difference and intentional incomparability between 2.6.28 and 2.6.30 kernels or it is rather result of my environment (i.e. something in kernel config should be changed) . Thx in advance
