Show Serial Number and Firmware Version

First, find out the device and bus numbers like this:

lsusb | grep tickle
Bus 003 Device 046: ID 04b4:bef0 Cypress Semiconductor Corp. tickle

then use the numbers from above to show the serial number:

udevadm info -a -n bus/usb/003/046 | grep ATTR{serial}

and the firmware version:

udevadm info -a -n bus/usb/003/046 | grep ATTR{bcdDevice}

This is the firmware version in hexadecimal, so 00.60 in decimal.

Check if you have the newest firmware available
