Hello,

I'm having trouble with flashrom, i have a working ft2232 board and i correctly connected a spi flash on it on port A
I also correctly installed the libusb drivers for the board
So i found a compiled version of flashrom for windows v0.9.6.1-r1705
I run it with this command
flashrom -p ft2232_spi:type=2232H,port=A
And i get this:
flashrom v0.9.6.1-r1704 on Windows 6.1 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

I then decided to try port B, so i wired the flash chip on port B and used this command
flashrom -p ft2232_spi:type=2232H,port=B
And i get this:
flashrom v0.9.6.1-r1704 on Windows 6.1 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Unable to reset FTDI device (USB device unavailable).
Unable to set latency timer (USB device unavailable).
Unable to set bitmode to SPI (USB device unavailable).
ftdi_write_data: -666, USB device unavailable
Error: Programmer initialization failed.

The chip i'm trying to work with is a MACRONIX_MX25L25635F, specified in the flashchips.h line 478 of the source code v0.9.8
#define MACRONIX_MX25L25635F    0x2019    /* Same as MX25L25639F, but the latter seems to not support REMS */

So i decided to cross compile the new version 0.9.8 for windows thinking that maybe the v0.9.6.1 doesn't recognise my chip ?
Anyway i installed mingw and used msys64 to get all the packages and update everything correctly, i also put the libusb and libftdi in the bin, lib and include directory, i think everything is installed correctly but...
When i try to compile flashrom with make i get this error
$ make

to the PKG_CONFIG_PATH environment variable

Please install libusb-0.1 headers or libusb-compat headers.

make: *** [hwlibs] Error 1

Could you help me out to compile le latest version of flashrom please ?

Thanks a lot for reading me
Best regards
