While debugging a problem with pcscd from security/pcsc-lite
06361622 hotplug_libusb.c:514:HPAddHotPluggable() Adding USB device: 3:2:0
00000191 hotplug_libusb.c:558:HPAddHotPluggable() libusb_open failed: -4
We (Damien and me) quickly found that the cause was:
16097 pcscd GIO fd 1 wrote 75 bytes
"04421857 hotplug_libusb.c:514:HPAddHotPluggable() Adding USB device:

I think only two /dev/ugen* are too few, what about increasing the
number a bit?
