I've updated to Digispark/Arduino version 1.5.8B and have been having some trouble getting sketches using the DigiJoystick library to compile.
I've received the following compilation errors:
Arduino: 1.5.8 (Windows XP), Board: "Digispark (Default - 16.5mhz)"
Build options changed, rebuilding all

Error compiling.
The compilation errors seem to be related to statements with PROGMEM.
I tried to resolve the issue by creating a backup of the DigiJoystick library (the folder C:\Program Files\Digistump_Arduino\hardware\digistump\avr\libraries\DigiJoystick\) and modifying the header file DigiJoystick.h to the file attached (search for mybook4 to see changes).
After making the changes above, I compiled again and noticed the following errors reported for usbdrv.c:

Error compiling.
I tried resolving these issues by making the changes to usbdrv.c (see attached file) (again, search for mybook4 to see the changes):
After these changes, the sketch compiled successfully, and the digispark was flashed. However, after flash and reset, the Digispark did not report itself to the host PC as a USB HID joystick. I did not troubleshoot deeper (yet), as I'm new to Digispark debugging.
