Sorry to waste your time I just realised my mistake..

When it was connected to Linux/MacOS a tool automatically ran which =
silently patched(!) the Cypress FX2 code (it reset the CPU but didn't =
cause a reconnection so I didn't notice).

After the code is patched the serial number command works (but xc3sprog =
blows up because it changes the protocol)
