My phone simply never detects the Digispark (anyone with a Digispark can test this
with the ArduinoDroid app, or with direct SDK programming). Digispark uses a
custom USB driver, not a catalog HID driver (for the record, USB HID keyboards do
work fine on my phone).
I'm told that the Digispark connects fine on other (non-EMUI non-Huawei) phones.
Can anyone confirm this, or better yet explain the problem? I suspect EMUI might
not open custom USB devices up for developer access...
Thanks for your help! I've been trying to debug this for weeks...and just giving up
