the wMaxPacketSize is 64 for both EP1 IN and EP2 OUT. There is
no alternative setting to have zero bandwitdh (zero endpoint or
wMaxPacketSize=0, typically for ISOC device) in this case
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x81 EP 1 IN
bmAttributes 2
Transfer Type Bulk
Synch Type None
Usage Type Data
wMaxPacketSize 0x0000 1x 0 bytes
bInterval 0

So you should probably fix the problem in your system and not
to change the libftdi codes.
