usb reset do not affect behaviour of firmware. At least after i remove

If adapter will got reset signal, FW will be notified about it. Then FW 
will remove reset flag and will just continue to work. After usb reset, 
lsusb show correct, update information - EP3 and EP4 was updated from 
INT to BULK.

I assume, no i need to add to the driver some kind of firmware check. 
What is the proper way to do it?

The simplest way is to put a new value for the device descriptor's 
bcdDevice value in the firmware.  Then all you have to do is check that 
value.
