It is better to use a USB MCU device which you have access to the firmware source code and can change the firmware. Many USB MCU boards will fit the bill, from ST, Microchip/AVR, NXP/Freescale, etc. Depending on which MCU you are familiar with, then you can choose from them. For example, I am mainly using an old USB PIC18F87J50 PIM since I can build the FW since Microchip provides the USB stack which provide quite some examples. I also have a few STM32 discovery kit which I use less since I am less familiar with the FW side. -- Xiaofan ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ pyusb-users mailing list pyusb-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pyusb-users
