Hello
I don't know if someone has already fix this, but in the 2.6.x kernels,
when using udev file system, you encouter some kind of delay (something
like 2 or 3 seconds) when you plug in a USB hotplug device (like CD
recorder, or whatever...).
I explain :
Normally, when you plug in such a device, the usb-storage module creates
a SCSI Generic device connected to your device for using it and adds it
to the /proc/scsi/scsi file.
With udev, it seems (I say it seems because I did not check the kernel
source yet) that the kernel is adding the SCSI Generic device in
the /proc file 2-3 seconds BEFORE this device gets useable (tested with
sg_scan).
Is it "normal" ?
Best Regards,
Mathieu
