The chip id 0x00 is currently not support in this program

[prosper00]

Linux (Ubuntu 20.10):

$ wchisptool 
Error while bulking in: LIBUSB_ERROR_OVERFLOW
Libre CH551 Flasher 2018
The chip id 0x00 is currently not support in this program

I did get a few compiler warnings when building:

$ make
cc -O2 main.c -o wchisptool `pkg-config --cflags --libs libusb-1.0`
main.c: In function ‘main’:
main.c:230:2: warning: ‘libusb_set_debug’ is deprecated: Use libusb_set_option instead [-Wdeprecated-declarations]

edit: the vnproch55 programmer used in ch55xduino works fine:

/home/bdroy/.arduino15/packages/CH55xDuino/tools/MCS51Tools/2020.12.01/linux/vnproch55x /tmp/arduino_build_302531/CMSIS_DAP.ino.hex

so does ch55xtool:

$ ./ch552tool.sh 
Found CH552.

So, I guess this is because new (since about a year ago) chips ship with bootloader version 2.40, which librech551 doesn't support.

For the benefit of anyone else stumbling onto this repo with this problem, the following flashers DO work with more recent chips:

VNPro (patched for more CH55x chips) (https://github.com/LoveMHz/vnproch55x) This is what's used in ch55xduino

ch55x-isptool (https://github.com/ElectronicCats/ch55x-isptool)
