Hi All, I'm using the c++ wrapper of libftdi (git co of yesterday) to communicate with a FT2232HL on a Lattice XO2 Eval board (LCMXO2-7000HE-B-EVN) this board has no programmed in iSerial. A simple c++ program which just opens and closes the device fails with "libusb_get_string_descriptor_ascii() failed" this is also true for the find_all_pp example (find_all, works). This failure originates in the use of the get_strings() function inside all c++ open() functions. This function wants all three iManufractuer, iProduct and iSerial to be present. The C-API allows one to pass NULL to ignore these descriptors. This is currently not possible with the c++ api. To properly fix this I suspect an api break is needed. As temporary ugly workaround I use the appended patch. Are there other ideas to fix this? Cheerio, Matthias
