The power key doesn't wake my OptiPlex 755. I was just dropping one of the USB data lines and I'm assuming that these newer PCs require that the proper USB protocol be followed for this. I doubt I'll be fixing this as I don't know how to add multiple interfaces (if I did, I'd have added media key support).

Host gets USB errors when resuming, which can reset a custom xmodmap on Linux.

TXD line on USBASP has a 1K series resistor, so we could use this as an ADB data line pullup, eliminating the need for getting a 1K resistor to build this project.

After waking PC, first two keys are reported in sorted order rather than pressed order. Occurs even when waiting several seconds after waking PC before pressing them.

During heavy typing, LEDs sometimes don't update when host changes them (e.g. when pressing caps lock). usbFunctionSetup() in usb_keyboard.c receives USBRQ_HID_SET_REPORT, but occasionally our usbFunctionWrite() doesn't get called.

When rebooting machine, doesn't switch into boot protocol for BIOS properly and is unresponsive. Works when machine is powered up from being off, though.
