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.

Since adding fw check will need fw version update. I would like to do quick fix for current kernel and firmware version. I will revert EP3 and EP4 from bulk back to interrupt. But, before sending patch to the list i would like to know, how to reproduce the bug which was fixed by converting this endpoints from interrupt to bulk.
