2021-01-06Allow disabling CDC with -DCDC_DISABLEDDaniel Gibson
Sometimes Arduino-based USB devices don't work because some hardware (like KVM switches) gets confused by the CDC sub-devices. This change makes it relatively easy to disable CDC at compiletime. Disabling it of course means that the serial console won't work anymore, so you need to use the reset button when flashing. CDC_DISABLED is also used in ArduinoCore-samd for the same purpose. based on https://github.com/gdsports/usb-metamorph/tree/master/USBSerPassThruLine See also https://github.com/NicoHood/HID/issues/225 and https://github.com/arduino/Arduino/issues/6387 and https://forum.arduino.cc/index.php?topic=545288.msg3717028#msg3717028
2019-02-17Define descriptor return var in pluggable blockDavid Madison
Avoids unused variable warning if USB is enabled but pluggable USB is not
2018-12-11Add USBDevice.isSuspended()Gergely Nagy
Based on code originally by Rob van der Veer <rob.c.veer@gmail.com>, this adds USBDevice.isSuspended(), so user sketches can run custom code in their `loop` methods after checking if the device is suspended or not. Signed-off-by: Gergely Nagy <algernon@keyboard.io>
2017-11-13Always read key to check for new LUFA bootloaderScott Allen
Instead of checking for the NEW_LUFA_SIGNATURE once in program memory and then setting a flag which is used for further checks, a function is used that always checks program memory directly. If a flag is used, there's a slight chance that its location in RAM could fall on MAGIC_KEY_POS. In this case, an aborted USB auto-reset sequence may fail.

2016-07-14Send an USB remote wakeup if data need to be writtenMartino Facchin
On Linux, setting autosuspend_delay_ms to N and control to auto allows the host pc to suspend the peripheral. Some Linux distro (Ubuntu, Mint) apply this behaviour by default. If the sketch's prints where less frequent than N milliseconds the sketch prints would never arrive. This patch allows sending a remote wakeup event to unsuspend the peripheral and allow the serial prints to be received.

2016-04-14Subtract one from USB_EP_SIZE in USB_SendSpaceSandeep Mistry
This avoids dealing with ZLP’s in USB_Send, because the max packet size will be EP size - 1.
2016-04-06[AVR] Discover newer bootloader at runtimeMartino Facchin
Replaces #4280, only checks for the bootloader once Tested with Hoodloader2, should work with every LUFA-derived bootloader released after 2014 (.apitable_signatures section must be placed at end of the flash) BootloaderAPITable.S : .global BootloaderAPI_Signatures BootloaderAPI_Signatures: .long BOOT_START_ADDR ; Start address of the bootloader .word 0xDF00 ; Signature for the CDC class bootloader .word 0xDCFB ; Signature for a LUFA class bootloader makefile: BOOT_API_LD_FLAGS += $(call BOOT_SECTION_LD_FLAG, .apitable_signatures, BootloaderAPI_Signatures, 8)

2015-10-07[PUSB] Made getDescriptor() and setup() more flexibleNicoHood
Alternatively we can only pass the wIndex to getDescriptor but I suggest to just pass the pointer aka reference of the whole setup. In guess (havent tested this) that this results in more or less the code size but its a) idential with the other functions and b) we late have more flexibility here. The Code got a quick SerialKeyboard.ino test

2014-05-24Fix race condition in USB CDC transmitPaul Brook
If the Start of Frame interrupt triggers just after the call to USB_SendSpace in USB_Send then we can get data loss. When the first bank is full and the second partially full, the SOF handler will release the second bank via USB_Flush. Data is then lost due to overflow as USB_Send continues writing data to the now-closed bank. Fix this by re-checking the FIFO status inside LockEP, immediately before doing the data write.
