FT_GetDeviceInfoList non-ASCII serial problem
« on: November 14, 2022, 01:47:51 PM »

we have encountered a problem with libftd2xx v1.4.27 on linux
FT_GetDeviceInfoList fills FT_DEVICE_LIST_INFO_NODE.SerialNumber with ASCII characters only
any non-ASCII character gets replaced with `?` == 0x3f
problem location best guess is: libusb_get_string_descriptor_ascii() at libusb included within driver package
same problem is with FT_GetDeviceInfo

while the same code works well on windows: serial number is returned correctly

can you please give a hint: how to retreive serial number value without any non-ASCII replacement?

Hello,

The solution would be to only use Serial Number or Description with ASCII characters.

You can use D2xx Programming functions in Linux to reprogram or you can use FT_PROG on Windows.

The alternative driver that you can try is LibFTDI which is an open source library/driver but is not created/supported by FTDI:

https://www.intra2net.com/en/developer/libftdi/

This third party solution includes the source so may suit you if you need to make changes to the source.

Best Regards,
