Re: group is not set properly for usb printer for older kernels

[Evangelos Foutras <foutrelis@gmail.com>]

I set udev's loglevel to "debug" and saw something interesting in my 
logs [1] after turning on the printer. Specifically, the following line 
appears to be of interest:

  Oct 12 19:38:26 foutboxd udevd-work[7541]: '/lib/udev/usb_id' (stderr) 
'error opening USB device 'descriptors' file'

Maybe the 'descriptors' file hasn't been created when the udev rules 
fire? I think this would explain why subsequent calls to udevadm 
test/trigger apply the correct group to the printer.

Random coincidence, my Canon PIXMA iP3000's print head died soon after I 
noticed the above error, more than three years after the printer was 
bought. Time to get a cheap laser printer (I'm considering the Samsung 
ML-1640) I guess, since getting a new print head for my old inkjet 
printer would cost more. :<

PS: Sorry for going a bit off-topic about my dead printer, I felt like 
talking about it a little. :(
