How do you think this answer will working. OK i can do it because i now
there is some thing wrong and i will decrees timeout to about 2 min but
it still not the proper way usb_supend handle this device. So may be it
will work instead of half a year - one year.

The problem is it will be not correctly disabled. Instead of laptop way
, park heads and spin down the rotor; it will be just power off. Some
thing like this i had on poweroffing of my laptop with broken libata or
acpi. It sounded like some airplane crash. Now it is fixed but the same
issue appear with this adapter. It is the kernel problem but the
question is: is it usb_mass_storage, libata or usb_suspend issue?
