"Unable to find device" on Linux, AMD #63
Description
blisp throws a "device not found" error while trying to flash a Pinecil V2. On the Pinecil docs, it's stated that the device will appear as a /dev/ttyACM* device, but this does not occur on my machine (AMD Ryzen 3600X, Arch Linux with current kernel).
The device is recognised, just not mapped to anything directly under /dev/. Here's part of the logs for udevadm monitor -p
