UHS_HID_KB_MOUSE.ino producing unrecognizable character

HID RAW/KEYBOARD/MOUSE demo Begin.

After comparing with UHS_HID_RAW.ino, found:

Producing unrecognizable character:
void onStart(UHS_HID_base *d) { printf_P("HID driver type %d started, Subclass %02x, Protocol %02x ",

Producing normal character:
void onStart(UHS_HID_base *d) { printf_P(PSTR("HID driver type %d started, Subclass %02x, Protocol %02x\r\n"),

After the above modification, other characters started playing but also unrecognizable:

BOOT_KEYBOARD
BOOT_MOUSE
HID driver type 2 started, Subclass 01, Protocol 02

case UHS_HID_mouse:
          printf_P(PSTR("Mouse buttons left %s right %s mid %s fourth %s fifth %s motion (X,Y) %4d,%4d wheel %4d"), squeek->bmLeftButton == 1 ? "t" : "f", squeek->bmRightButton == 1 ? "t" : "f", squeek->bmMiddleButton == 1 ? "t" : "f", squeek->bmButton4 == 1 ? "t" : "f", squeek->bmButton5 == 1 ? "t" : "f", squeek->dX, squeek->dY, squeek->wheel1);

If line printf_P is commented out unrecognizable characters stop appearing, Something may be wrong in this line.

And yes, should be PSTR

I tried using the UHS_HID_RAW.ino example with Mega2560, and noticed that a message is displayed even when disabling debug mode, I may have to add some #ifdef entry there:

UHS_HID.h file:

Line 146:

From:
printf("Length %d ", length);
To:
//printf("Length %d ", length);

Nice find, I'll patch it when I get the chance.
