hi all:
Is there any test program we can use to capture input data send from
usb keyboard/mouse?
I don't need to parsing the binary sent by keyboard/mouse. Just raw
data is fine.
I checked the Kernel sample, hid-example.c, but it seems only get
report and print it out.
appreciate your help in

Maybe one of the programs that reads the mbr partition table can
be persuaded to do a direct read

Create a dummy file on the disk and let cron touch it every 4 minutes.

To save the IO, kernel will keep the file in page cache as much as
he can and under this circumstances, the scsi command may disappear
for a while longer enough to cause the device suspend.
