#152 (comment)

The iocontrol module has been refactored:

• Moved some code from the get_usb_string_descriptor() to the get_descriptor_id();
• Changed the return of the get_usb_string_descriptor() to Result<String, Error>.

#152 (comment)

The iocontrol module has been refactored:

• The get_usb_string_descriptor() associated function has been renamed to get_string_descriptor();
• Removed unnecessary code from the get_string_descriptor() function related to language ID specification:
  • Now SetupPacket.wIndex is being set to 0 instead of GetSystemDefaultLangID's return;
  • I have not encountered any problems using lpinbuffer.SetupPacket.wIndex = 0. Let me know if anyone finds it necessary to specify the Language ID ¹.
