I hear the typical reset priorities for a Usb Mass device from least to greatest are:
suspend (means power cycle if bus-powered)
class-specific reset
vendor-specific forms of reset
port reset (means power cycle if bus-powered)
power cycle
That these resets are not equivalent is a fact of life, driven to more or less
prominence by anything that looks like a cache: head position, self-powered RAM,
speed-matching FIFOs, mode pages, defect management, user-level write-cacheing, you
name it.
That these resets are not equally effective is a mark of imperfection wherever that's
true. To my eye, the demos most likely to provoke action are demos of forms of reset
that can be demoed ineffective either in the latest idProduct for an idVendor or
across more than one idProduct of an idVendor ... I wonder if anybody has such demos
in place?
