* USB-CDC: accepting the next data packet only if we process previous data * USB-CDC: use USB FS packet size * HAL-console: puts method * Check: print assertion data * FuriHal: rx stream free space aware CDC confirmation. * Bootloader: pull down USB lines, leave the rest to the firmware or bootloader * F6: cleanup and move USB code to usb-glue folder, add USB suspend/resume events to VCP, cleanup target.mk, fix missing motd message in cli when using minicom. * F5: cleanup the rest of USB glue code, adjust LPM and Power info data in descriptor.
