I just purchased 5 of the above from Digikey here in the USA. I wanted to setup 5 of them using the olimex-arm-usb-tiny-h*.cfg  with unique serial numbers in the entry. Turns out that one of them has a duplicate serial number. Is this expected?
Can I change the serial number?



Sure you can change it. This information is stored in the FTDI chip. Use MPROG to change it.

Refer to chapter "3.5.2 Changing the VID and PID of the debugger" on page 22 of the manual:

Important!!! Do not change the VID and PID or you will brick the device and will need to make custom drivers for the new VID and PID that you assigned, MAKE SURE TO CHANGE JUST THE SERIAL NUMBER!!!
