UsbHostHub_KM example fails to compile about ch554_sdcc HOT 5 CLOSED

SDCC 4.0.7 ...
Compiles with printf_small instead of printf (#define printf printf_small in usbhost.c and UsbHostHub_KM.c) - I have not checked if code was working on real hardware yet.

from ch554_sdcc.

Great! I'll try it on real chips as soon as they arrive. I bought a bunch to play with, and am excited to try them out

from ch554_sdcc.

Code compiles and 'works', but debug information on the Uart output is not the expected one...

Start @chipid=T2X (should be : printf( "Start @chipid=%02X\n", (uint16_t)CHIP_ID ); )
Wait Device In
Query Mouse @␀4X
Query Mouse @␀4X

I think it would be better to remove all printf and replace by some custom putstring/printhex to reduce footprint.

I have made some tests on my github repository : the ch554_sdcc debug code as library (the linker will not include getchar for example), and 4 functions to print str/hex2/hex4/linefeed (also as library). Not very clean regarding the Makefile. It fits with full debug in usbhost and Usb_Host_KM.
Result looks like this on TX pin P3.1 (9600bps)

I got my 554's in the mail today! Can confirm that these tweaks work.

Thank you! I'm totally going to poach your library too :)
