Thanks! I've opened separate issues for the bugs. I will look into the truncated prd error later. Can you test the workaround for the suspend bug I've posted in https://github.com/quo/ithc-linux/issues/9?

@csdvrx Thanks! It sounds like the device uses standard HID (possibly with some nonstandard Wacom things?) instead of the MS Surface HID protocol. This means that you probably don't need...

@csdvrx As I suspected, according to the descriptor the data on the X1 Fold is just normal HID data. The reason iptsd gives the 'block' errors is because it can't...
